Osiris Receives $5 Million Milestone Payment

Osiris Therapeutics announced today that it has received $5 million in payment for having reached the first production threshold of the Osteocel supply agreement with NuVasive. In a business deal that was valued at $85 million, Osiris sold Osteocel, its bone matrix product, to the San Diego-based spine specialization company NuVasive Inc. in July of 2008 for an initial payment of $35 million which is to be followed by further payments totalling an additional $50 million when milestones are reached.

According to NuVasive chairman and CEO Alex Lukianov, “Osteocel provides what we believe to be one of the more powerful biologic platforms on the market today.” Osiris CFO Richard Hunt adds, “It is through the hard work and dedication of our Osteocel team that we have achieved the first product supply milestone under the agreement and are solidly on track to hit the remaining milestones. With more than 15 years of rigorous stem cell research and development behind it, today Osteocel stands alone in orthopedics. Along with our excellent partners at NuVasive, we look forward to the product’s continued success.”

A leader in adult stem cell therapies, Osiris Therapeutics is focused on the development of products for the treatment of inflammatory, orthopedic and cardiovascular diseases. One of its proprietary adult stem cell products, Prochymal, is currently in Phase III clinical trials for the treatment of Graft-versus-host disease and Crohn’s disease, and is also being evaluated for the repair of heart attack damage, the protection of pancreatic beta islet cells in patients with type 1 diabetes, and for the treatment of chronic obstructive pulmonary disease. Another product, Chondrogen, is currently undergoing evaluation for the treatment of arthritis in the knee. With an extensive intellectual property portfolio containing 47 patents, Osiris has formed a partnership with Genzyme Corp. for the development and commercialization of Prochymal and Chondrogen in countries outside of the U.S. and Canada.

Genzyme on Track to Meet 2011 Financial Goal

With 2009 earnings that are estimated at $4.70 a share, and despite the current dismal global economic conditions, Genzyme has announced that it is on track to meet its goal of 20% compound earnings growth, or $7.00 growth per share, by 2011.

Unlike many companies whose stock has evaporated in recent months, Genzyme enjoyed a 13% growth in revenue which rose to $1.17 billion in the final 3 months of 2008. The company bases its projections of continued sustainable growth through 2011 upon strong sales of its proprietary drugs for rare and chronic diseases, for which Genzyme currently has more than a dozen novel therapies in its pipeline, several of which are expected to receive FDA approval in the coming year alone.

Speaking in Boston at the Goldman Sachs conference on healthcare, Genzyme’s CEO, Henri Termeer, expressed confidence that the company will continue to expand internationally, especially into the so-called “BRIC” countries, namely, Brazil, Russia, India and China. According to Termeer, “The key here is to bring other programs in to create growth drivers when we get there. I would suggest that any company that does not become competent in how to do business in those countries in a way that is sustainable will be missing an opportunity over the next 10 to 20 years.”

Genzyme’s stock closed today at $65.41 per share, up $1.29 from its previous close yesterday.

Cord Blood America Begins a Media Campaign via Social Networking Websites

One of the leaders in the growing field of the cryopreservation and banking of umbilical cord blood stem cells, Cord Blood America, is now poised to become a leader in the use of social networking websites. Realizing that the recent explosion in the popularity of such sites heralds the dawn of a new era of change and opportunity, not only in technology but also in business, Cord Blood America has announced its plans to seize such an opportunity. From now on, clients, shareholders and investors, both current and prospective, will be actively engaged with all the latest developments at Cord Blood America through social networking sites such as Twitter, Facebook and FriendFeed, among others. Cord Blood America intends to use the social networking sites to develop relationships and to build networks as well as to answer questions regarding their business and the basic science of stem cells.

In a statement issued by Cord Blood America, founding CEO Matthew Schissler offered the following invitation: “It’s time to start the conversation. The word ‘stem cells’ invokes many thoughts, yet we have found that the vast majority of the population still does not know what they are, where they come from or how they dramatically impact almost all aspects of life as we know it. To most, ‘stem cells’ is a scientific term that has no direct impact on the individual. It’s our belief that most people want to understand in a practical fashion how stem cells affect their family directly. This is the purpose of the social media, to deliver in a user-friendly fashion practical information about stem cells. We intend to look at the issue from multiple angles, including medically from the eyes of the patients and health care practitioners, fundamentally from the scientists, economically from the investor and business perspective, and socially from a public policy perspective. Social media is growing explosively and this trend, according to all authorities, is going to continue. We believe that building a network of clients and investors in two-way communication via social media will establish ourselves and our business as market leaders of the future. We invite you to join us in the conversation at the outlets previously mentioned. Additionally we have set up a social media newsroom at Intelligendo.com. We will leverage this newsroom and Intelligendo to further our relationship and network building efforts.”

Cord Blood America is the parent company of CorCell, an umbilical cord blood adult stem cell preservation company that services expectant parents and their children.

International Stem Cell Corporation Receives First Round of Funding

International Stem Cell Corporation (ISCO) announces the receipt of the first $1 million tranche of an anticipated $5 million in private equity financing that is to be spread out over the following months.

According to CEO Kenneth Aldrich, “This is a first major step toward the company’s goal of becoming financially self-sufficient.” Jeffry Janus, president and COO of ISCO, adds, “Although additional financing will be needed in 2009 to reach our goal, we believe our Lifeline subsidiary has the ability to bring the company to profitability within two years and support the clinical research of the company thereafter.” The company’s “Lifeline” subsidiary produces the particular stem cell lines in which the company specializes and from which the bulk of revenue is expected to be generated.

ISCO is the creator and developer of a new class of stem cells that are produced from its proprietary “parthenogenesis” technology, by which “parthenote cell lines” are obtained from unfertilized eggs that contain only the DNA of the donor and which therefore involve neither fertilized ova nor embryos. Parthenote cell lines are diploid and contain a full complement of genes and can be differentiated into all major cell types. As described on ISCO’s website, parthenote cell lines “display typical hESC (human embryonic stem cell) morphology, differentiate into all three embryonic germ layers and are immune matched (Major Histocompatability Complex matched) to the donors.”

ISCO’s parthenote cell lines have already been differentited into retinal cells, human corneal tissue, liver cells and heart cells, and work is currently in progress to differentiate the the cells into pancreatic beta islet cells.

Anthrogenesis Receives Another Patent for Placental Stem Cell Innovation

In a patent application that Anthrogenesis filed on June 22, 2004, materials and methods are detailed at length for the extraction, recovery, isolation, propagation, collection and utilization of “embryonic-like stem cells, including but not limited to pluripotent or multipotent stem cells from an exsanguinated human placenta”. Further described within the application is “an isolated human placental stem cell” with the ability to differentiate into cells of neural, osteogenic, and chondrogenic phenotypes, among others.

Although it is certainly not the first and will probably not be the last, this is the most recent patent to be awarded to Anthrogenesis Corporation for its placental stem cell technology.

Anthrogenesis was acquired by Celgene in 2003, and operates as a wholly owned subsidiary of Celgene. Founded in 1986, Celgene has grown to a multinational biopharmaceutical company that employs approximately 1,600 people around the world.

Located in New Jersey, Anthrogenesis Corporation is a recognized leader in pioneering the technological means and methods for the derivation and commercialization of large quantities of adult stem cells that are found in human placental tissue. According to John Jackson, chairman and CEO of Celgene, “Placental stem cells have the potential to transform the way physicians treat serious diseases and the way novel therapies are developed.”

Apparently, however, the news of this latest patent has not yet reached Wall Street, as Celgene’s stock closed at $53.48 today, down 24 cents from its close yesterday.

U.S. Doctor Plans Stem Cell Fact-Finding Mission to China

Ophthalmologist David Klein has accepted an invitation to travel to the People’s Republic of China in the hopes of learning first-hand about human stem cell therapies that are currently being conducted outside of U.S. borders. In particular, Dr. Klein will focus specifically on medical advances that have been made with adult stem cells that are derived from umbilical cord blood.

As Dr. Klein explains, “A lot of Americans assume that if it’s being done overseas, they’re experimenting on human beings. I’m going into it with an open mind.”

Dr. Klein first became interested in learning about stem cell therapies when several of his patients returned to the U.S. after having traveled overseas to receive stem cell treatments that have not yet received FDA approval to be conducted within the United States. Dr. Klein became especially interested after observing the progress of a 2-year-old patient who had suffered from optic nerve hypoplasia, which is a leading cause of blindness in children, and for which American doctors told the parents that no treatment exists. The family researched other options, however, and in 2007 they traveled to China where they visited a clinic that uses adult stem cells derived from umbilical cord blood. The therapy consisted of 4 infusions of the stem cells into the child’s arm and lumbar region of the spine, and by the third treatment the child was able to see well enough to stand on his own and crawl toward objects, which he had previously been unable to do. By the fourth treatment, the child could see objects at a distance of ten feet away and began attending school. According to his grandmother, the boy “has made huge improvements. There was nothing for him before this treatment. Now, his world is limitless.”

Stem cell “tourism” is a thriving industry, in which increasing numbers of people are flocking to foreign clinics overseas in search of therapies that are not yet legal within the United States. Precisely for this reason, one of the main criticisms against the U.S. FDA (Food and Drug Administration) is that its laws are outdated and no longer apply to new medical technologies such as those that require approval for the use of stem cell therapies. Before any new therapy can become legal within the U.S., it must undergo rigorous scientific and clinical scrutinization that can take a decade or longer and cost the company that is developing the therapy hundreds of millions of dollars. While no one questions the importance and necessity of such testing for safety and efficacy, many scientists do question the lethargic pace at which such testing is often conducted. Increasingly, there are many patients with life-threatening illnesses and injuries who cannot afford to wait a decade or longer to receive a treatment that could literally make the difference between life or death. When such people are forced to travel outside of their home countries in search of any therapy that offers any hope at all, even false hope, the dangers to which these patients are exposed are potentially greater than those that they would face without any treatment whatsoever. Although there do exist a number of scientifically reputable and legitimate stem cell clinics outside of the U.S., these clinics are often competing against the many disreputable and illigitimate “clinics” that offer only bogus, illicit “therapies”, and it is not always easy for the average person to distinguish between these two types of clinics. What is urgently needed now more than ever is an updated overhaul of the U.S. FDA regulatory system, so that those therapeutic stem cell methods which are safe and effective can be made legally available within the U.S. in as timely a manner as possible, while at the same time the laws must also be updated to protect patients from medical treatments that are not verifiable as safe and effective. If such a revision of the FDA approval process were to occur, the direction of stem cell “tourism” might be reversed, with many patients throughout the world traveling to the U.S. in order to benefit from sound medical treatment, rather than so many U.S. citizens having no other option but to travel outside of the U.S. in search of any glimmer of hope.

Meanwhile, Dr. Klein is looking forward to his fact-finding mission to China. Although he has described himself as “cautiously optimistic” about stem cell therapy, he wisely adds that “I want to make sure there’s good science behind it.”

His trip is planned for 2009.

Neuralstem Files FDA Application for ALS Adult Stem Cell Trial

Neuralstem Inc. announced this morning that it has filed an IND (investigational new drug) application with the U.S. FDA (Food and Drug Administration) to begin the first ever human clinical trials for the treatment of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, with adult stem cells.

According to Richard Garr, J.D., president and CEO of Neuralstem, “Like all first human trials, this proposed trial is primarily designed to test the safety and feasibility of both our stem cells and our method of delivering the cells to the spinal cord in ALS patients. We are also proposing secondary endpoints which we hope will be able to measure a slowing down of the degenerative process.”

The treatment will consist of spinal injections of the adult stem cells using the company’s patented and proprietary technology. The clinical trials will take place at Emory University under the direction of Dr. Johnathan Glass, Director of the Emory Neuromuscular Laboratory and Director of the Emory ALS Center, pending offical FDA authorization.

Approximately 30,000 people in the U.S. alone are afflicted with ALS, which is a progressive neurodegenerative disease in which the deterioration of nerve cells and motor neurons progresses from a loss of muscular control to paralysis and ultimately death. Conventional medical modalities have thus far been unsuccessful in halting or reversing the course of the disease, which until now has been considered incurable. Adult stem cell therapies, however, constitute the first type of treatment that is actually capable of offering realistically achievable improvement.

According to Richard Garr, “The filing of this IND is an important event for Neuralstem, but it marks only the beginning of a process which includes working together with the FDA to approve the first human ALS stem cell trial, refining our understanding of how to optimize delivery of our cells into patients, and ultimately delivering a new treatment for patients with this currently incurable disease.”

As described on their website, “Neuralstem, Inc. is a publicly traded biotherapeutics company whose mission is to apply stem cell research and its patented human neural stem cell technology to treat diseases of the central nervous system including ischemic paraplegia, traumatic spinal cord injury, ALS and Parkinson’s disease. Our stem cell research has resulted in patent-protected technology that allows us to produce mature, commercial quantities of neural stem cells with the ability to control the differentiation of the cells into physiologically relevant human neurons and glia.”

Genzyme Receives FDA Approval for Mozobil

The biotech company Genzyme has received approval from the FDA for the marketing of its proprietary adult stem cell stimulating product, Mozobil, which is a novel, proprietary small-molecule CXCR4 chemokine receptor agonist. When used in combination with G-CSF (granulocyte-colony stimulating factor), Mozobil has been shown to increase the number of stem cells circulating in the peripheral blood by mobilizing hematopoietic stem cells in the bone marrow and stimulating the cells to migrate into the bloodstream for easier collection and subsequent autologous transplantation.

According to John DiPersio, M.D., Ph.D., a professor at Washington University in St. Louis, “Mozobil is an important advancement in the treatment of patients with certain types of cancer who require a stem cell transplant. This product should become an integral part of the treatment regimen for transplantation because of the benefits it offers to patients, physicians and transplant centers.”

In order to receive an autologous (in which the donor and recipient are the same person) adult stem cell transplant, each patient must be able to donate a minimum of 2 million stem cells per kilogram of body weight. After being collected, isolated and expanded, the adult stem cells are then administered to the patient as part of the therapy. For some patients, the collection process alone can take hours, spread out over multiple days, and for those patients who are not able to mobilize enough stem cells for the collection, the transplant is not possible. By mobilizing a patient’s endogenous stem cells and by stimulating the stem cells to migrate from the bone marrow into the bloodstream, Mozobil facilitates the therapeutic adult stem cell process, especially for patients who might not otherwise be able to receive such a therapy at all.

According to Joseph Lobacki, senior vice president and general manager of Genzyme’s transplant and oncology division, “Mozobil is an exciting and innovative new treatment that expands Genzyme’s contribution to the field of hematology and oncology. We look forward to strengthening our partnership with the blood and marrow transplant community to make this product broadly available to patients who are facing transplantation procedures for non-Hodgkin’s lymphoma or multiple myeloma.”

Approximately 55,000 hematopoietic stem cell transplants are performed each year globally for multiple myeloma, Hodgkin’s and non-Hodgkin’s lymphoma, for which Mozobil is expected to be used in the majority of such cases. Peak annual sales of Mozobil are projected to reach $400 million. Genzyme has also submitted applications to the respective regulatory agencies in Europe, Australia and Brazil for marketing approval of Mozobil, and additional applications in up to 60 countries are planned.

Founded in 1981, Genzyme now has more than 10,000 employees around the world with revenues in 2007 of $3.8 billion. With products and services available in nearly 90 countries worldwide, Genzyme focuses on the treatment of rare inherited disorders, kidney disease, orthopedics, cancer, transplantation, and diagnostic testing. In 2007, Genzyme was awarded the National Medal of Technology, the highest honor awarded by the President of the United States for technological innovation.

Adult Bone Marrow Stem Cells Treat Heart Failure in an Infant

Doctors in Germany have reported improvement in the cardiac function of a 2-year-old child who was critically ill with severe heart failure caused by dilated cardiomyopathy (DCM), and who improved after receiving autologous adult stem cell therapy.

Led by Dr. Stefan Rupp of the Pediatric Heart Center at Justus-Liebig University in Giessen, Germany, the team of physicians conducted an intercoronary administration of autologous adult progenitor cells derived from the infant’s own bone marrow. As described in their article, “DCM is the most common cardiomyopathy in childhood. Effectiveness of anticongestive therapy is limited in most cases and about one-third of children diagnosed with DCM die or receive heart transplantation within the first year after diagnosis.”

This case documents the first instance of an autologous adult stem cell treatment administered to a patient this young, whose condition was progressively worsening despite maximal anticongestive therapy prior to receiving the autologous adult stem cells, and who has consequently shown measurable improvement as a result of the autologous adult stem cells.

As the authors conclude, “Cardiac stem cell therapy proved to be technically feasible, was associated with improvement in cardiac function, and might represent an option before heart transplantation in children with severe heart failure.”

New Vatican Document Offers Strong Support for Adult Stem Cells

In what can hardly be considered a surprising document, the Roman Catholic Church has released a new publication addressing matters of bioethics. Referred to simply as “Dignitas Personae” (“The Dignity of the Person”), a shortened version of the full title which is “Dignitas Personae – Instruction on Certain Bioethical Questions”, the 23-page-long document takes a serious look at recent advancements in biomedical science and the resulting ethical dilemmas. The purpose of the document is to offer guidance not merely to Roman Catholics, but “to all who seek the truth”, as is stated on page 2 of the Introduction.

Although this document itself is new, its intrinsic message is not. The stance reiterated throughout all 23 pages is the same thesis that is always promoted by the Catholic Church, namely, that “the Magisterium of the Church has constantly proclaimed the sacred and inviolable character of every human life from its conception until its natural end.” (p. 10) It should therefore come as no surprise to anyone, whether or not one agrees with such a stance, that this is the basic premise of the document. According to the website of the United States Conference of Catholic Bishops, the new Vatican document offers instruction “on ethical issues arising from biomedical research” and “provides guidance on how to respect human life and human procreation in our heavily scientific age.” In fact, the paper is in may ways an updated, modernized version of another Vatican “instruction” document, “Donum Vitae” (“The Gift of Life”), which was issued in 1987 under the pontificate of John Paul II, and to which “Dignitas Personae” makes repeated reference. “Instruction” documents, which are not authored directly by a Pope but are approved by a Pope, are not to be confused with papal encyclicals, which are authored directly by a Pope, such as “Veritatis Splendor” (1993) and “Evangelium Vitae” (1995), both of which were personally written by Pope John Paul II, and the more controversial “Humanae Vitae” which was written in 1968 by Pope Paul VI, all of which reinforce the same themes as “Donum Vitae” and “Dignitas Personae”.

Critics of the Vatican and of Roman Catholic Church policy often point out, and justifiably so, previously erroneous stances taken by the Church in the past, most notably in the field of science. One of the most egregious examples involved the trial of Galileo in 1633 by Pope Urban VIII, during which Galileo was found guilty of promoting the “heretical” view of a heliocentric solar system (in which the sun, not the earth, is located at the center), for which Galileo was imprisoned and then sentenced to house arrest for the remainder of his life. Only in 1992 did the Church finally and officially exonerate Galileo, when Pope John Paul II expressed public regret for the incident that had occurred over 3-and-a-half centuries earlier. As Church critics will also point out, the legal body which interrogated and imprisoned Galileo, for the “heresy” of defending what is now known to be a scientific fact, was none other than the ecclesiastical tribunal infamously known as the “Inquisition” and which today is known by the name of “The Congregation for the Doctrine of the Faith” – the very same Church institution which issued “Dignitas Personae”. Such facts, coupled with the highly publicized priest scandals in recent years, have not given the Roman Catholic Church a very admirable public-relations image. Nevertheless, there do exist modern bioethical dilemmas, which are the result of recent breakthroughs in medical science, and there are people throughout the world who do seek guidance and moral direction on such topics. Since very few other organizations are issuing formal “doctrinal instruction” in such matters, documents such as “Dignitas Personae” are received with widespread and genuine interest. Whether or not the instruction offered by such a document will ever actually be followed, however, is yet to be seen.

It has commonly been observed that the Vatican does not update its official doctrine casually nor hastily. Nevertheless, although it took nearly 4 centuries for the Church to apologize for the Galileo incident, it has taken only 21 years for “Donum Vitae” to be updated with “Dignitas Personae”. Indeed, the relatively swift and timely release of “Dignitas Personae” at this particular moment in history is seen by many as an indication of the urgency and the importance with which the Church views the bioethical problems that are the focus of the document.

Contrary to popular opinion, the Roman Catholic Church is not against stem cell research in general, but, more specifically, is only against embryonic stem cell research. Such objections are not random nor without basis, since the derivation of embryonic stem cells requires the destruction of an embryo, which is an act that most theologians, Christian and otherwise, believe to be morally and ethically wrong. By sharp contrast, however, as is clearly stated in “Dignitas Personae”, the Roman Catholic Church is strongly in favor of research and therapies that involve adult stem cells. As stated on page 19 of the document, “Research initiatives involving the use of adult stem cells, since they do not present ethical problems, should be encouraged and supported.” Even with research and therapies that fall exclusively within the adult stem cell realm, however, the authors of the document are clear in their emphasis that, “Such use should be characterized by scientific rigor and prudence, by reducing to the bare minimum any risks to the patient and by facilitating the interchange of information among clinicians and full disclosure to the public at large.” The central argument of the document, in effect, is one that calls for serious ethical consideration of all aspects of biomedical science, not only in those fields that involve the use of stem cells.

Of the 23 pages that constitute “Dignitas Personae”, the topic of stem cells is only specifically addressed on pages 18 and 19. The rest of the document examines other issues, such as in vitro fertilization, the cryopreservation of embryos and oocytes, “embryo reduction”, intracytoplasmic sperm injection (ICSI), forms of interception and contragestation, the manipulation of embryos and of “the human genetic patrimony”, reproductive and therapeutic cloning, gene therapy and germ line cell therapy, transgenic experimentation and hybrid cloning with human somatic cellular nuclei that are reprogrammed within nonhuman mammalian oocytes, among other topics – all within the context of “anthropological, theological and ethical aspects of human life and procreation.” Following the Introduction, the paper is divided into 3 sections which progress systematically through successive logical developments that build upon what the authors describe on the first page as “principles of Christian anthropology”. In authoring this document, the Congregation for the Doctrine of the Faith assures its readers that it has “consulted numerous experts with regard to the scientific aspects of these questions”.

The paper is not meant to be an exhaustive scientific treatise on all aspects of modern medicine, and some topics are conspicuous by their absence, such as, most notably, iPS (induced pluripotent stem) cells. Teratomas are also never explicitly mentioned, per se, although there are many scientists throughout the world who seriously question whether embryonic stem cells can ever be usable as a safe and viable medical therapy due to the innate tendency of embryonic stem cells to form the specific type of tumor known as a teratoma. Since adult stem cells do not carry any risk of forming teratomas, and since adult stem cells are already being used as clinical therapies throughout the world, there are many scientists who do not advocate embryonic stem cell research but who do advocate adult stem cell therapies, for reasons that have nothing to do with religion, theology or ethics, but which have everything to do with principles of sound science and with the practical realities of medicine. Nevertheless, “Dignitas Personae” boldly addresses all of the uncomfortable, most emotionally charged and sensitive ethical issues that are unavoidably entangled in stem cell research, and which most scientists and researchers diplomatically go out of their way to try to avoid.

Theologians are not the only people who believe that many aspects of modern science “call for attentive moral discernment”, as the authors of “Dignitas Personae” assert. To borrow another phrase from the Vatican document, for many people there still remains the nagging, seemingly unresolved question of whether embryonic stem cells might possibly be something more than just “biological material”. Indeed, classes and entire departments in “bioethics” are springing up in law schools throughout the U.S. with increasing popularity, a prime example of which was the founding in 2005 by Harvard Law School of an entire center, “The Petrie-Flom Center for Health Law Policy, Biotechnology and Bioethics”, precisely to provide a forum in which legal experts can debate and address, and formulate legislative policy on, such issues. With an increase in the number and types of new therapeutic modalities that are developed within the various medical specializations, the number and types of litigation are also expected to increase, and a new generation of lawyers who specialize in bioethics is currently being groomed to meet the future legal needs of a world that will be dramatically unlike the world for which current laws were designed. Even though doctors and scientists may not be formally addressing matters of medical bioethics, the lawyers are. If not for an interest in ethical reasons per se, then perhaps for an interest in legal ramifications, the scientific and medical communities might wish to join the conversation.

Outside of medicine, in many other branches of science, such as with the growing concern over ecological consequences of combustible fuel, a strong sense of ethics is encouraged and applauded. Even outside the realm of science, such as with the recent global economic crisis, there is a loud outcry for serious legal reform requiring transparency, responsibility, accountability and oversight, both at the corporate and at the individual levels. Similarly, “Dignitas Personae” calls for nothing more nor less than the same type of objective ethical standards to be applied to medical science. Without “an ethical point of reference”, that is, without some sense of prudence, without concern for the safety and dignity of others, and without a high degree of personal responsibility and accountability built into the system, the authors of the document warn that it is all too easy for people to “surrender to the logic of purely subjective desires and to economic pressures which are so strong in this area” (p. 9), especially in the potentially lucrative field of regenerative medicine.

As stated on page 2 of the Introduction of “Dignitas Personae”, the authors seek “to offer a word of support and encouragement for the perspective on culture which considers science an invaluable service to the integral good of the life and dignity of every human being.” As such, the authors make a compelling argument for “the ethical use of science”. In clear and direct language, “Dignitas Personae” specifically “calls everyone to ethical and social responsibility for their actions.” (p. 6) Although many people will not agree with the particular details of the stance that is promulgated by this particular document, most people will still agree that at least an open and healthy debate on such topics might be more productive than a systematic attempt to ignore the topics categorically. The authors also recall the words of Pope John Paul II, who made an “appeal to the conscience of the world’s scientific authorities and in particular to doctors”, but in “Dignitas Personae” it is everyone – patients and doctors alike – who are summoned to an honest and critical examination of conscience.

Regardless of one’s religious affiliation, and whether or not one has any religious affiliation at all, most if not all people, especially scientists, would probably agree to an ethical and responsible use of the modern powers of science and technology. The precise definitions of “ethical” and “responsible”, however, are currently the subject of widespread disagreement. One topic over which there is no disagreement nor debate at all, however, is the fact that embryonic stem cells cause teratomas, since this is, by definition, the gold standard by which pluripotency is identified in laboratories throughout the world. For anyone who may seek “guidance” in the field of stem cells but who prefers to avoid theological inquiry altogether, such people need look no further than the topic of teratoma formation for one of the many exclusively scientific reasons to be extremely cautious when considering embryonic stem cells as a medical therapy. Since adult stem cells are already in use in clinics around the world, as real therapies in the treatment of real human beings with a wide range of real diseases and injuries, and since adult stem cells do not pose any of the numerous medical risks that embryonic stem cells pose – such as biological contamination and genetic mutation in addition to teratoma formation, among other problems – the use of adult stem cells has already been proven as both legitimate and responsible science. Religion and politics aside, in the use of adult stem cells, there is no discrepancy between science and ethics.
