BioTime Announces Agreement With Millipore

BioTime has announced that its wholly owned subsidiary, Embryome Sciences, has entered into a marketing collaboration with Millipore. According to the terms of the agreement, Millipore will become the worldwide distributor of ACTCellerate(TM) human progenitor cell lines, which are derived from human embryonic stem cells (hESCs) but are not yet fully differentiated. Although researchers hope that the cells may ultimately have therapeutic applications, currently the cells can only be used for drug screening and for further experimental research.

According to Donald O’Neil, director of marketing for stem cells and cell biology at Millipore, "The Millipore team is committed to supplying high quality products to transport the emerging field of regenerative medicine to an increasing level of sophistication. We believe that Embryome Sciences’ novel, highly-purified and scalable progenitor lines have potential to be a significant breakthrough for the industry, and we’re excited to feature them in our rapidly growing family of novel stem cell lines, media, antibodies, cultureware, and characterization kits."

As BioTime and Embryome Sciences CEO, Michael West, Ph.D., adds, "Many researchers prefer to work with well-characterized progenitor cells rather than starting from scratch with embryonic stem cells. The ACTCellerate(TM) product line gives scientists a jump-start on their research by providing a reliable, highly purified source of characterized human progenitor cells from a variety of lineages. We look forward to working with Millipore’s outstanding marketing team to make these cell lines widely available to scientists worldwide, allowing them to more quickly perform the research and development work that may lead to life-saving therapies."

As described on Millipore’s website, "Millipore’s initial offering of Embryome Sciences’ products will include six novel progenitor cell lines and optimized ESpan growth media for the in vitro propagation of each progenitor cell line. Additional cell lines will be introduced frequently, as Embryome Sciences has already isolated over 140 distinct progenitor cell types. The companies anticipate jointly launching 35 cell lines and associated ESpan growth media within the coming 12 months." Unlike traditional methods, the ACTCellerate lines are generated via a two-step multiplex process that isolates and purifies progenitor cells from different lineages in a rapid manner by which the cells are also selected for scalability, robustness and then characterized for gene marker expression as well as phenotype.

Headquarterd in Alameda, California, BioTime is focused on the development and commercialization of technology and products related to blood plasma volume expanders for use in emergency trauma treatment, surgery and related applications. Its wholly owned subsidiary Embryome Sciences is "focused on developing an array of research and therapeutic products using human embryonic stem cell technology", as described on the personal website of Michael West, Ph.D., molecular gerontologist and BioTime’s CEO. Prior to his work with BioTime, Dr. West founded the Geron Corporation, which received FDA approval earlier this year to commence the first human clinical trials ever to be conducted with hESCs.

Millipore Corporation is an S&P 500 company with nearly 6,000 employees worldwide.

New Director of NIH Chosen

President Obama has nominated the acclaimed geneticist and former head of The Human Genome Project, Francis S. Collins, M.D., Ph.D., as the new director of NIH. Dr. Collins will assume the new leadership of NIH pending his Congressional confirmation hearings, which are expected to proceed smoothly.

The announcement comes just one day after NIH released its guidelines governing human embryonic stem cell research.

As President Obama stated, "My administration is committed to promoting scientific integrity and pioneering scientific research and I am confident that Dr. Francis Collins will lead the NIH to achieve these goals."

Dr. Collins has been described as an "evangelical Christian who has defended the inherent compatibility of science and religious beliefs", and although Dr. Collins has a sterling reputation among scientists, reactions from the media are mixed, as critics point out that the religious views which Dr. Collins espouses may interfere with an impartial and objective scientific approach to directing NIH. In an article entitled "Obama Names an Evangelical to Lead the NIH", a U.S. News & World Report article states that "Obama this week picked a Bible-believing, loud, and proud evangelical Christian to head the National Institutes of Health." Any personal religious views to which Dr. Collins might ascribe have certainly not interfered with his scientific objectivity in the past however, as a number of media sources point out, among which is the Wall Street Journal which reported the news in an article the title of which simply read, "Obama Plans to Name Renowned Geneticist to Head NIH."

Dr. Collins earned a B.S. in Chemistry from the University of Virginia in 1970, a Ph.D. in physical chemistry from Yale in 1974, and an M.D. from the University of North Carolina at Chapel Hill in 1977. He first distinguished himself at the University of Michigan where he gained recognition for his pioneering work in positional cloning, a type of genetic screening and gene identification technique. In 1993 he accepted an invitation to succeed Dr. James Watson (Nobel laureate and co-discoverer with Dr. Francis Crick of the helical structure of DNA) as director of the National Human Genome Research Institute (NHGRI), one of 27 institutes within NIH, which he directed from 1993 to 2008. During this time Dr. Collins also became director of the Human Genome Project, an international research project which resulted in 2003 in the successful mapping of the genetic sequences of 3.1 billion chemical base pairs in the human DNA. Along with Craig Venter, founder and former president of Celera Genomics as well as the founder of The Institute for Genomic Research, Dr. Collins was awarded the "Biography of the Year" award in 2000 by the A&E Network, and U.S. News & World Report together with the Harvard Center for Public Leadership named both Collins and Venter "America’s Best Leaders" in 2005.

In 2006 Dr. Collins authored the book, "The Language of God: A Scientist Presents Evidence for Belief", in which he describes scientific discoveries as an "opportunity to worship". Dr. Collins awknowledges that he has been highly influenced by C.S. Lewis, especially by the book "Mere Christianity" to which Collins attributes his conversion to Christianity at the age of 27. Currently Dr. Collins serves as president of The BioLogos Foundation, which he founded in 2009, the mission of which is to "contribute to the public voice that represents the harmony of science and faith."

Dr. Collins has received numerous awards and honors throughout his career, including election into the National Academy of Sciences, the Institute of Medicine, and the Presidential Medal of Freedom.

This year the NIH will have $40 billion at its disposal for funding medical research, including that which is to be conducted on human embryonic stem cells.

Bangor Family Heads to Central America for Adult Stem Cell Therapy

Kenneth Kelley, an eight-year old child from the Bangor area will be the first person from Maine to receive adult stem cell therapy for autism. Stem cell therapy for the treatment of autism has been performed in many North American children who have traveled to the ICM clinic in Central America, with several news reports of patient improvements, and one scientific publication from the group supporting the rationale for this therapy (Ichim et al. Stem Cell Therapy for Autism. 2007 Jun 27;5:30).

Autism is a disorder of the brain that occurs as a child is growing up, and is associated with repetitive behavior, lack of ability to interact socially, and impaired communication skills. To date there is no cure for autism, although a variety of experimental interventions are being performed with varying degrees of success.
Adult stem cell therapy for autism is based on the idea that a chronic inflammatory condition in the gut of autistic children may resolve or at least diminished from the healing effects of the mesenchymal stem cells. The other stem cell type that is used for treatment of autism comes from the cord blood. Cord blood stem cells have been demonstrated by numerous American and international scientific groups to secrete factors that promote healing of nerves and enhance oxygenation of the brain.

Marty Kelly, mother of Kenneth, like many parents of autistic children, initially could not believe the diagnosis of autism. Kenneth was 2 years old when his doctors made the diagnosis, which is believed to be made in as many as 1 in 144 children. Marty Kelly, determined to do something about it, arranged for Kenneth to start receiving hyperbaric oxygen treatments for her son, which caused an improvement in his condition. According to her:

"One of the first things we did was buy a hyperbaric oxygen chamber and within a couple of days, he actually sat down and traced the alphabet from A to Z by himself which was huge. First time he’d ever done that."

Hyperbaric oxygen increases growth factor production in the brain, as well as, by providing oxygen theoretically overcomes some of the problems reported in autistic children such as poor oxygenation of certain parts of the brain. In the case of Kenneth, while there were improvements, these were not cures and the underlying condition still caused significant suffering in the Kelley household:

"It’s really hard because he just we can’t go anywhere and we can’t have anyone over. He just screams all day."

Marty is confident adult stem cell therapy will cause benefits in Kenneth based on knowledge of previous children who have been treated with varying degrees of success.

To discuss and learn more about adult stem cell therapy for autism, an Autism Biomedical support group is being created. The first meeting is july 18th at 10 am. To learn more, call 942-2459.

Boston’s biotech community leads wave of stem cell consolidation, deal making

Today at the ISSCR Meeting in Barcelona, the merger of two stem cell companies, IZumi Bio and Pierian Inc was announced, with the new company being named IPierian. According to the new company’s website iPierian is

"…a pioneering biopharmaceutical company that is taking the cutting-edge technologies of cellular reprogramming and directed differentiation to an entirely new level to harness the power of induced pluripotent stem cells to advance the understanding of human diseases and accelerate the discovery of more effective therapeutics for patients"

The two precursor companies, iZumi and Pierian, both had synergistic skills in the area of inducible pluripotent stem cells (iPS), a type of "artificial stem cell" that is created from skin or other tissues. The use of iPS cells for therapeutics development is more attractive to scientists than embryonic stem cells for several reasons. Firstly, iPS cells can be generated to be patient-specific, thus overcoming problems with need for taking of immune suppressants. Currently embryonic stem cells can not be used in patients for several reasons, and the few times that their use is contemplated, the patient is sentenced to taking life-long immune suppression so that they do not undergo rejection. Secondly, iPS cells can be generated under highly defined conditions. Embryonic stem cells that are currently used have been developed years ago and face various problems such as the fact that many of them have previously been grown on mouse cells or using animal products. In contrast, iPS cells can be generated with relatively little effort.

iZumi was supported by the venture capital groups Kleiner Perkins Caufield & Byers and LExington, Mass.-based Highland Capital Partners with a $20 million investment, whereas Pierian was founded by MPM Capital managing directors Ashley Dombkowski and Robert Millman as well as Harvard University scientists. The new company, which will be led by John Walker as CEO and Corey Goodman, as Chairman, raised an additional $10 million from Boston-based MPM Capital and $1.5 million from FinTech Capital Partners.

Initial goals of the company will be use of the iPS cells to address disease affecting the central nervous system that have no effective treatment such as spinal muscular atrophy, Parkinson’s Disease, and ALS. In the long-run the company plans to investigate conditions such as heart failure, liver failure, and diabetes. As part of the new company’s strategy, it will seek synergistic collaborations with established market players.

Despite the aggressive goals the company has set for itself, there are several drawbacks that one must consider. Firstly, pluripotent stem cells, regardless of whether they are iPS or embryonic stem cells, all cause cancer when administered into animals. iPS may be especially dangerous since oncogenes (genes that cause cancer) are needed for the creation of these cells. In order for iPS to be used safely, it will be necessary to make sure that the cells being made for injection are completely the cells that one wants, and no contamination with the original iPS cells. In other words, if one is treating Parkinson’s Disease, one can not simply inject iPS cells into the area of the brain that is damaged, since this conceptually will form a tumor. In contrast, one would have to "teach" the iPS cells to become the specific cell that is damaged in Parkinson’s Disease, called the "dopaminergic neuron", one will have to concentrate these cells outside of the body, and then inject them directly where they are needed. Once the cells are injected, they will have to form connections with the existing cells and subsequently integrate and take over their function. This is in contrast to the present-day clinically available adult stem cell therapies, where in many cases adult stem cells are injected either intraviously or intrathecally, and the natural signals of the body instruct them to differentiate into the needed tissue. Although differentiation efficacy of adult stem cells may be lower on a per cell basis, of the thousands of people that have been treated with adult stem cells no reports of tumor formation exist.

iPierian’s scientific leadership comes from the respected embryonic stem cell experts Dr. George Daley, Douglas Melton and Lee Rubin who are faculty at Harvard. The scientific advisory board (SAB) of the company will be chaired by Dr. George Daley, and will include Amy Wagers, Kevin Eggan, Benoit Bruneau, and Matthias Hebrok.

Cellular Dynamics Creates iPS Cells From Human Blood

Today on their website, Cellular Dynamics International (CDI) announces the successful reprogramming of an ordinary human blood cell into an iPS (induced pluripotent stem) cell. The findings will be officially presented two days from now, on July 10, at the annual conference of the International Society for Stem Cell Research (ISSCR) which is being held this week in Barcelona, Spain, from July 8 – 11.

As reported on CDI’s website, "This significant breakthrough provides a readily obtainable source of pluripotent stem cells from the millions of samples in storage at blood repositories and healthcare institutions worldwide." As further stated on CDI’s website, these findings "demonstrate that any stored blood sample is a candidate for iPS cell reprogramming."

According to Chris Kendrick-Parker, chief commercial officer of CDI, "Industry’s challenge was to reliably create iPS cells from a commonly available and easily accessible tissue source and we focused on stored human peripheral blood samples. Generating pluripotent stem cells from small volumes of blood – either freshly collected from a patient or accessed from blood storage repositories, provides a convenient source for generating patient-specific stem cells that are valuable research tools and may one day be used as a cellular therapy to treat disease."

As Emile Nuwaysir, chief operations officer of CDI, adds, "The ability to use common tissue repositories to create iPS cells from donors with known medical history enables us to provide the pharmaceutical industry with a cell portfolio representing individual biology, disease models, retrospective analysis and ethnic diversity. This is the first step in paving the way for large-scale processing and industrialization of iPS cells."

As further described on CDI’s website, "To generate the induced pluripotent stem (iPS) cells, CDI scientists isolated T-cells, a type of white blood cell, from a 3 ml donor blood sample. The cells were stimulated, expanded and exposed to documented reprogramming factors. iPS cell colonies were observed after three weeks. Analysis revealed that the iPS cells are functionally identical to embryonic stem cells and iPS cells generated from other human tissue sources, that they carry the same genetic background as the source blood sample, and that they have the pluripotent ability to differentiate into any cell type."

Previously, iPS cells had first been created from the skin cells of mice and then from the skin cells of humans. The successful creation of iPS cells from human blood cells demonstrates, at least conceptually, that iPS cells could possibly be created from any type of somatic (non-stem cell) cell. Not only does such a breakthrough eliminate the ethical dilemmas associated with embryonic stem cell research, but it also allows for the creation of patient-specific stem cell therapies.

Of course, patient-specific stem cell therapies are already available with autologous (in which the donor and recipient are the same person) adult stem cells, and experts such as Dr. James Thomson point out that even iPS cells still have another decade to go before they are safe enough to be considered viable for clinical applications. Furthermore, there is really no need for the development of patient-specific stem cell therapies since there already exist certain types of allogeneic (in which the donor and recipient are not the same person) adult stem cells which are known as "universal donor", "immune privileged" cells, meaning that they do not pose any risk of immune rejection, and which are also already clinically available. Nevertheless, this recent breakthrough in the creation of iPS cells from ordinary somatic blood cells represents further proof of the obsolescence of embryonic stem cells as a candidate for clinical therapies.

This week at the ISSCR annual conference, CDI will officially announce and describe their latest iPS cell breakthrough during a poster session that begins at 4:45 p.m. on July 10. (Please see the related news article on this website, entitled, "New Technology Breakthroughs Showcased at Annual Stem Cell Conference", dated July 10, 2009).

High School Coach Heads to Central America for Adult Stem Cell Therapy

Diagnosed in 2005 with multiple sclerosis, Sam Herrell had few options available to him in the U.S., his home country. Now, however, he is traveling to Central America in order to receive an adult stem cell therapy that was pioneered by American doctors but which is not yet available within the United States.

A proud native of Texas, the Ennis Lions football coach has decided to travel to ICM – the Institute for Cellular Medicine – in Central America for treatment with his own adult stem cells. The ICM has an 80% success rate with its patients, but don’t expect the treatment to be available any time soon within the U.S., since the U.S. FDA (Food and Drug Administration) has made such a procedure legally impossible for doctors to conduct within the United States. Specifically, the FDA has decreed that autologous (in which the donor and recipient are the same person) adult stem cells must be classified and regulated as a "drug", and therefore cannot be used as a clinical therapy until first being subjected to the ordinary FDA laws that govern pharmaceutically manufactured drugs, which is a process that typically requires a decade or more of testing before approval can be obtained. Most patients, with multiple sclerosis as well as other diseases or injuries, cannot wait a decade or longer for treatment, so they are following the U.S. doctors who have set up their clinics outside of U.S. borders. If the FDA would only change their stance on this critically important issue, then the U.S. doctors who pioneered this adult stem cell treatment would be able to administer the therapy within the U.S., and then perhaps there wouldn’t be such an endless debate over embryonic stem cells, which still have years if not decades left before they could be considered for use in clinical therapies. Unlike embryonic stem cells, adult stem cells are already being used in clinics around the world to treat real people with real diseases – but not within the U.S., except for the very limited number of FDA-approved clinical trials that are being conducted.

As Sam Herrell explains, "The thing that’s kind of disappointing is that the neurologists here have nothing that really gives you much hope. All they can do is say keep on this medication and hope it slows down, hope it doesn’t overtake your whole nervous sytsem before they find a cure. Outside the U.S., some things are being done that people have had phenomenal results with, and that’s been encouraging. I really think there’s going to be a cure for it – that’s what I’m hoping for. It’s been encouraging to hear those stories and talk with people."

A number of scientific studies in the medical literature support such claims, not the least of which is an article that was published in the Journal of Translational Medicine in April of 2009, entitled, "Non-expanded adipose stromal vascular fraction cell therapy for multiple sclerosis", by N.H. Riordan et al., in which scientists and doctors elucidate the various cellular and molecular mechanisms that are at work when this type of autologous adult stem cell therapy is implemented as a treatment for multiple sclerosis. Additionally, 3 case studies are described in the paper in which patients with multiple sclerosis showed significant improvement after receiving such a treatment. Of particular significance are the unique immunomodulatory properties of this therapy, which play an especially vital role in a disorder of autoimmune origin such as multiple sclerosis.

In specific reference to ICM, Mr. Herrell adds, "I’ve heard of two different procedures I really think I’ll try. It’s very expensive, but that’s a hurdle I can try to tackle for hope of a cure. I get excited when I talk to those people who have gone outside the country, because they’ve come back with a story of hope. I’m still hopeful for a cure. I’m serious about that. These people who have tried some of these things, they don’t feel better, they feel cured. That’s what I’m hoping for. Then I can still live in Texas."

However, the U.S. FDA still insists that the cells within a person’s own body are "drugs" and therefore cannot be administered, not even to that very same person, for therapeutic purposes until first being subjected to the exact same multi-year, multi-million dollar approval process by which the pharmaceutical industry is regulated. Unless the FDA ever changes its position on this issue, people such as Sam Herrell will be forced to travel outside of the U.S. in order to be treated with their own, autologous adult stem cells.

Fortunately, at least such therapy does exist somewhere in the world, even though not in the United States.

Can Stem Cells Become Sperm Cells?

Scientists at the Institute of Human Genetics in the Northeast England Stem Cell Institute at Newcastle University in England have announced the creation of human spermatozoa from embryonic stem cells. Their study, published in the medical journal Stem Cell and Development, addresses an issue that influences the lives of approximately 7.3 million Americans: infertility.

In an article entitled, “In Vitro Derivation of Human Sperm from Embryonic Stem Cells”, Dr. Karim Nayernia and his colleagues describe a procedure by which human male gametogenesis is modeled in vitro. From human embryonic stem cells (hESCs), the scientists established male germline stem cells (GSCs) which were then stimulated to enter meiosis, thereby generating haploid motile “sperm-like” cells in vitro. Most strikingly, these “sperm-like” cells were able to mimic many of the properties of functional human sperm. While the current study used embryonic stem cells, which thus would not be viable for practical use in the treatment of infertility, the scientists are now trying to generate sperm from iPS (induced pluripotent stem) cells, a type of stem cell derived from somatic (non-stem cell) cells which mimic embryonic stem cells in its pluripotency. (More information about iPS cells may be seen on the video available at this link: iPS cells video). However, a full elucidation has not yet been provided for the precise ways in which these “sperm-like” cells – which the researchers have named in vitro derived (IVD) sperm – may or may not be identical to naturally occurring sperm.

As Dr. Nayernia explains, “We have a system which enables us for the first time to produce human sperm from stem cells. Studying sperm maturation is not accessible in vivo. You cannot follow the system. Now we have a system to monitor the stages of male infertility. This is very amazing and very exciting. They have heads, they have tails and they move. The shape is not quite normal nor the movement, but they contain the proteins for egg activation.”

The abnormal motility and morphology of the IVD sperm are of serious concern to a number of other scientists, however, for whom such a procedure raises a number of questions. According to Dr. Edmund Sabanegh Jr., director of the Center for Male Infertility at the Cleveland Clinic, “Some groups have raised questions about the research. There are huge ethical and safety implications of this. In theory, it’s exciting for couples that are struggling with this problem.” As Dr. Byron Petersen, associate professor in the Department of Pathology at the University of Florida, adds, “I would be very skeptical at this point and really look at what they define as sperm. An actual moving sperm cell or just a haploid cell that can be used to implant into an egg cell? The devil is in the details and it will be how they define their cell phenotype and what-not.”

This recent publication is an extension of previous studies that Dr. Nayernia and his colleagues conducted three years ago, at which time they developed a similar in vitro process for mouse sperm. When the IVD mouse sperm were used to inseminate mice in order to produce offspring, however, the newborn mice that were created from the artificial sperm died shortly after birth. A number of scientists therefore question the genetic viability of the IVD sperm as well as the viability of the technique by which each spermatozoon is artificially derived.

Although it is currently illegal in the U.K. as well as in the U.S., among other countries, to try to use the artificially derived human IVD sperm to fertilize human ova in order to create human offspring for reproductive purposes, it is still legal under U.K. law to use the IVD sperm to fertilize human ova in order to create human offspring for research purposes, as long as any embryos created by this method are destroyed by 14 days of age. Even if it were legal to allow such embryos to continue developing for reproductive purposes, the consequences could be disastrous if the IVD sperm were genetically unstable or flawed.

Although embryonic stem cells (ESCs) are so highly coveted because of their alleged pluripotency, in actuality the single celled human zygote – from which all ESCs develop – is totipotent. While totipotency (from the Latin “totus”, meaning “total” or “complete”) describes cells that are capable of differentiating into embryonic as well as extra-embryonic cell types, by contrast, pluripotency describes cells that are only capable of differentiating into embryonic cell types – namely, all cell and tissue types of the body, from all 3 germ layers – but not extra-embryonic cells and tissue, such as the placenta. Both male and female haploid gametes – spermatozoa and ova – are derivable from a population of “primordial germ cells” (PGCs) and “germline stem cells” (GSCs) which arise in early embryogenesis and later develop into the gonocytes that are responsible for gametogenesis, namely, spermatogenesis in males and oogenesis in females. In males it is not until long after birth that the gonocytes begin differentiating into adult male germline stem cells, known as spermatogonial stem cells (SSCs), which are both self-renewing and capable of producing spermatozoa. As the authors describe, SSCs “are unique stem cells in that they are solely dedicated to transmit genetic information from generation to generation.” While somatic (mature, non-stem cell) cells throughout the body are diploid (containing 46 chromosomes), gametes (ova and spermatozoa) are haploid cells (containing 23 chromosomes). The ability to generate such a highly specialized cell as a haploid spermatozoon from a diploid ESC is therefore significant not only because of the possible therapeutic medical applications but also because of the particular pathway by which primordial and germline cells are used for the in vitro acceleration of gametogenesis. As Dr. Nayernia further points out, “Other cell types don’t generate the next generation. This makes a very big difference between our study and the study of other cell types from embryonic stem cells.”

While the particular focus of this study was male gametogenesis, some scientists have begun to extrapolate similar procedures that may be applicable to female gametogenesis. Although Dr. Nayernia and his team were unsuccessful in trying to differentiate IVD sperm from female embryonic stem cells – as one would logically expect, since the Y chromosome must be present for sperm maturation – nevertheless other researchers are hypothesizing ways in which it might be possible to differentiate IVD ova from female embryonic stem cells, which contain only the X chromosomes.

As more and more people are waiting until later in life to have children, infertility is a growing problem around the world, especially in developed nations. According to a 2002 National Survey of Family Growth conducted by the Centers for Disease Control and Prevention in Atlanta, Georgia, it has been estimated that approximately 7.3 million people in the U.S. alone suffer from infertility, more than one third of whom are male.

If it could be possible to create safe and viable human spermatozoa from an alternate source, such as from embryonic stem cells, the procedure could have widespread therapeutic applications in reproductive medicine. In the wrong hands, however, there is also the risk of commercial exploitation.

Dr. Robert Lanza is adjunct professor at the Institute of Regenerative Medicine at Wake Forest University School of Medicine and chief scientific officer of Advanced Cell Technology Corporation (ACTC) – the company previously directed by the pioneering molecular gerontologist Michael D. West, Ph.D., who served as chairman of the board, chief scientific officer, CEO and President of ACTC from 1998 until 2007. ACTC specializes in the cloning of animals, including transgenic animals (hybrid species containing the genes of different species, usually human genes in combination with nonhuman genes), as well as in the controversial technique known as “therapeutic cloning”. Nevertheless, according to Dr. Lanza, and in specific reference to the possibility of creating artificial sperm, “What’s most concerning about this potential technology is that anyone, young or old, fertile or infertile, straight or gay, could potentially pass on their genes to a child from just a few cells. For instance, if you had a few skin cells from Albert Einstein – or perhaps even a hair follicle from the Pope or Queen Elizabeth – you could generate pluripotent stem cells. Any couple could go to an IVF clinic and have a child that is half, say, Albert Einstein, or perhaps Brad Pitt or Elizabeth Taylor.” It seems as though a number of technical hurdles remain to be overcome, however, before such concerns could materialize. Nevertheless, no doubt it is just a matter of time before such technological glitches are resolved, and many people wonder how the national laws and scientific guidelines of regulatory and oversight agencies will be able to address such changes. As CBS reporter Peter Allen cautions, “What these and other researchers are doing is ripping up the codes of law and morality by which we conduct our lives. The pace of discovery has left our legislators floundering.”

Indeed, while Dr. Lanza’s concerns may sound like science fiction, the generation of iPS cells has previously been performed from many types of tissues that can easily be stored across decades if not also centuries. Although it is somewhat of a barrier that iPS cells have not yet been made into sperm cells, thus far every cell type that has been generated from embryonic stem cells has also been generated from iPS cells. Accordingly, the ethical questions of using such technology should be addressed as soon as possible, since scholars believe it will be within the next decade that frozen somatic cells such as skin cells will be successfully used for the generation of new sperm.

Dr. Nayernia and his colleagues used a special “cocktail” of growth factors, nutrients and retinoic acid (a derivative of vitamin A), among other chemicals, to create the IVD sperm from embryos that were discarded from IVF clinics. As previously mentioned, Dr. Nayernia and his colleagues are now working on developing a similar method for the creation of IVD sperm from mature somatic skin cells derived from infertile men.

As the authors conclude in their publication, “Understanding the mechanisms of germ cell specification, development and its differentiation to sperm is important for elucidating the causes of male infertility. … While the full potential of the human ES-derived germ cells and sperm remains to be demonstrated, this in vitro modeling of human gametogenesis provides a new approach for studying the biology of human germ cells and for the establishment of therapeutic approaches in reproductive medicine.”

On the other hand, the findings of Dr. Nayernia and his colleagues, although exciting, still have several drawbacks. For example, these cells have not been able to successfully fertilize a human egg and generate offspring. This is actually the vital test, although it has not yet been successfully performed – and given the problems that were encountered when Dr. Nayernia and his colleagues attempted the procedure three years ago in mice, it might be quite awhile before such a procedure is successfully accomplished in humans – with or without the laws that forbid such experimentation.

Perhaps an even more significant and relevant study for male infertility, which did not receive as much media exposure as Dr. Nayernia’s, was that reported by Swerdloff’s group from Los Angeles. (Lue et al., ‘Fate of bone marrow stem cells transplanted into the testis: potential implication for men with testicular failure’, Am J Pathol 2007 Mar;170(3):899-908). In this study the scientists found that the administration of bone-marrow-derived adult stem cells into the testicles of mice could generate new cells that look and act like sperm. Implications of such a study might include new procedures for the treatment of infertile males that involve the therapeutic use of the patient’s own bone marrow. Additionally, an independent German group (Dursenheirmer et al., ‘Putative human male germ cells from bone marrow stem cells’, Soc Reprod Fertil Suppl. 2007;63:69-76) has also reported that bone-marrow-derived adult stem cells can be induced to become the cells that give rise to sperm cells based on the expression of specific proteins on the surface of the cells. From studies such as these, one can only conclude that the prospects for developing infertility treatments with stem cells are encouraging, with advances being made both from bone-marrow-derived adult stem cells and from embryonic stem cells, despite the many technological hurdles that still remain.

Certainly no one is more aware of such technological hurdles than Dr. Nayernia, who adds, “We think, for normal structural development, sperm needs the testes environment. In the human, sperm development is a very long process. It takes more than 15 years and is not an accessible system. With this system, we can now watch that development in three months.”

But in regard to the ethical and legal dilemmas that are engendered by such procedures, we are only just beginning to see the tip of the iceberg. As Dr. Insoo Hyun, a bioethicist at Case Western Reserve University, explains, “We have the potential therapeutic use of a technology that pushes the boundaries of what people feel comfortable with ethically. This area has potential powerful clinical applications mixed with people’s concerns over embryo research. All the ingredients are there for a really, really lively ethical debate.”

NIH Issues New Guidelines

Attempting to establish a new direction for national policy, today the National Institutes of Health released the final copy of its Guidelines on stem cell research.

The Guidelines are in response to President Obama’s Executive Order 13505, issued on March 9, 2009. According to NIH, "These Guidelines implement Executive Order 13505, as it pertains to establish policy and procedures under which the NIH will fund such research, and helps ensure that NIH-funded research in this area is ethically responsible, scientifically worthy, and conducted in accordance with applicable law. Internal NIH policies and procedures, consistent with Executive Order 13505 and these Guidelines, will govern the conduct of intramural NIH stem cell research."

On April 23 of this year, NIH published a draft of the Guidelines for research involving human embryonic stem cells (hESCs), after which a "comment period" lasted for approximately the next month, until May 26, during which time NIH accepted comments from the general public.

Under the new Guidelines, NIH has established a review process by which scientists will be able to use many of the hESC lines that already exist and which were created by private funding. Newly established hESC lines will qualify for research provided certain criteria are met, such as rules pertaining to "voluntary and informed consent" from the donors. In other words, the donors must be informed in writing of other options for their surplus embryos, as well as of the fact that any embryo donated for scientific research will be destroyed in the process. Financial as well as nonfinancial compensation of any kind is forbidden in return for the donated embryos. Additionally, embryo donors must be allowed to change their minds within a specified time frame, and they must not expect medical nor financial benefits from their donated embryos. Additionally, NIH funding will only apply to hESCs that are obtained from the surplus embryos of IVF clinics and which were created specifically for reproductive purposes, not for scientific research.

Issues relating to informed consent were among the most hotly debated points of the earlier draft version of the Guidelines, which would render most of the already existing hESC lines ineligible for funding. In order to address such concerns, NIH has agreed to establish a review panel to determine if some of the already existing cell lines might still qualify for federal funding.

In the new Guidelines, NIH has still banned the federal funding of any hESC lines that might be created from so-called "therapeutic cloning" methods, more correctly known as somatic cell nuclear transfer (SCNT), which is also the same procedure used in reproductive cloning. Despite the fact that no one has ever actually succeeded in deriving a hESC line from SCNT, nevertheless there are many ESC scientists who had hoped that NIH would allow funding of hESCs that might someday be created by this highly controversial procedure.

By some accounts, as many as 60% of the comments that NIH received in regard to their earlier draft of the Guidelines had come from people who expressed disapproval of the use of taxpayer money for research that will destroy human embryos. According to the Catholic News Service, at least 30,000 of the 48,955 comments which NIH received were from individuals and organizations who voiced opposition to hESC research but who strongly favored adult stem cell research instead. However, NIH dismissed such comments as being "not responsive to the question put forth." In a July 6 telephone briefing to the media, Dr. Raynard S. Kington, acting director of NIH, reacted to this fact by stating, "We did not ask them whether to fund such funding, but how it should be funded."

According to Cardinal Justin Rigali, Chairman of the U.S. Catholic Bishops’ Committee on Pro-Life Activities, "The comments of tens of thousands of Americans opposing the destruction of innocent human life for stem cell research were simply ignored in this process. Even comments filed by the Catholic bishops’ conference and others against specific abuses in the draft guidelines were not addressed."

According to Cardinal Rigali, NIH failed to address specific abuses of hESCs which might potentially occur after the cell lines have been obtained. Even though Section IV of the Guidelines specifically prohibits the introduction of hESCs into "primates," as well as the "breeding" of human cells with the cells of primates, nevertheless the laboratory creation of other types of "chimeras" and human-nonhuman mixed species is still allowed. As Cardinal Rigali adds, "For example, federally funded researchers will be allowed to insert human embryonic stem cells into the embryos of animal species other than primates. Federal grants will be available even to researchers who themselves destroyed human embryos to obtain the stem cells for their research. Existing federal law against funding research in which human embryos are harmed or destroyed is not given due respect here."

Both conservative and liberal critics of the new NIH Guidelines point out that the final version differs minimally in substance from the earlier draft proposed in April. Those who are in favor of hESC research criticize the new Guidelines for complications that may result from the "voluntary and conformed consent" rules, as well as for not allowing funding of future hESC lines that might be obtained from SCNT. Pro-life supporters, on the other hand, criticize the new Guidelines for having ignored nearly two-thirds of all comments received from people who advocated adult stem cell research over embryonic stem cell research.

Even though the new Guidelines forbid the federal funding of any research conducted on human embryos that are deliberately created only for research purposes, the Legislative Director of the National Right to Life Committee, Douglas Johnson, echoes the concern of many scientists as well as non-scientists when he states that, "This seeming restraint is part of an incremental strategy intended to desensitize the public to the concept of killing human embryos for research purposes. The Obama Administration today slides further down the slippery slope of exploiting non-consenting members of the human species – human embryos."

Geron and GE Form Partnership

The embryonic stem cell company Geron, and the multinational conglomerate General Electric, have announced the signing of a global licensing agreement in which Geron will provide human embryonic stem cells (hESCs) to GE’s Healthcare division for the toxicity testing of drugs. The hESCs will not be used for the development of cell-based therapies.

According to a statement that GE made in 2005, "GE will not be associated with the primary harvest of human embyro-derived cells or tissues. We acknowledge the considerable debate and take very seriously the ethical and societal issues associated with research using stem cells derived from embryonic or fetal tissue. We conduct our research in an ethically and scientifically responsible manner."

Therefore, according to Geron, the hESCs that are to be provided to GE were derived from human embryonic stem cell lines that were approved under policies established by the Bush administration in 2001. Contrary to popular misconception, hESC research was not forbidden under the Bush administration but in fact was conducted in laboratories and corporations across the entire United States during the entire Bush presidency. As long as the research met specific guidelines, it even received federal funding, and if it did not meet those guidelines then the research was usually conducted anyway, but with private funding instead of federal funding.

Under the new agreement between GE and Geron, Geron will provide the hESCs to GE who will develop and commercialize lab equipment that facilitates the use of the hESCs in drug development and toxicity screening. The lab equipment will then be marketed to pharmaceutical companies and research labs. According to Konstantin Fiedler, general manager of cell technologies at GE’s Healthcare division, the market for toxicity testing is expected to be in the hundreds of millions of dollars by 2020, from which Geron will begin receiving royalties by 2010.

Scientists from both companies will collaborate in the venture, with GE Healthcare providing all R&D funding. According to David Earp, senior vice president for business development and chief patents counsel at Geron, "We had an asset that we were not able to exploit fully." According to Konstantin Fiedler, general manager of cell technologies at GE Healthcare, "This agreement marks a further step in GE Healthcare’s cell technology strategy aimed at addressing the potential of stem cell applications in the drug discovery and therapy markets."

In 2008, GE earned over $17 billion in revenue, of which approximately $1.5 billion was through its life-sciences related business, which GE began expanding in 2003 with a number of acquisitions and parnerships that included the $9.5 billion acquisition of Amersham PLC, a biotech firm based in the UK which had developed specialized technology in nucleic acid blotting, radiochemical labeling and detection. Other acquisitions and partnerships in the biotech sector have included an agreement between GE and the StemSource technology division of Cytori Therapeutics, a stem cell banking company whose products GE will commercialize in ten European countries. (Please see the related news article on this website, entitled, "Cytori and General Electric Agree Upon Collaboration", dated May 8, 2009). In the past, most of the revenue generated from GE’s Healthcare division has come from diagnostic and imaging equipment, sales of which are declining in response to the efforts by public and private insurers to reduce costs. GE is now in the process of plans to reposition its business strategies.

In January of this year, Geron received FDA clearance to commence the first hESC clinical trials ever to be performed, which were to begin in the summer. Results of the trials will not be obtained for years, however. (Please see the related news article on this website, entitled, "FDA Approves First Human Embryonic Stem Cell Trial", dated January 23, 2009).

Contrary to popular misconception, actual cell-based therapies are still years away for hESCs, and even decades away by some accounts – which is precisely why this new licensing agreement between Geron and GE involves the use of hESCs not for the development of cell-based therapies, per se, but for the use of the hESCs in the development and toxicity testing of drugs. Even Dr. James Thomson, "the father of embryonic stem cell science", who was the first person ever to isolate a hESC in the laboratory, has emphasized this point on a number of occasions. His own company, Cellular Dynamics International (CDI), which he cofounded in 2004, also specializes not in the development of clinical therapies from hESCs, but instead in the use of hESCs for drug development and toxicity testing. (Please see the related news article on this website, entitled, "Cellular Dynamics and Mount Sinai Sign Licensing Agreement", dated May 29, 2009).

Financial details of the agreement between Geron and GE were not disclosed.

Geron’s shares rose 15% after the announcement, to $7.67, while GE’s stock fell to $11.72.
