Stem Cells from Testicles – Another Non-Controversial Breakthrough

Stem cell taken from men’s testicles could be transformed into a wide range of tissue types to help fight disease. United States researchers have come up with a new use for the rich source of stem cells.

The cells were reprogrammed to be heart cells, blood vessels, and other tissues after scientists isolated and extracted them form the testes of male mice.

Cancer, heart disease, strokes, Parkinson’s disease and other conditions could all be treated if the results can be duplicated using in humans. The ethical concerns surrounding embryonic stem cells would also be negated by this breakthrough.

Shahin Rafii continued to work long and hard on the project since the testes provide such a potentially rich source of stem cells. He spent years working and now the payoff is evident. Rafii is a doctor at Weill Cornell Medical College in New York.

“Testes are designed to generate a lot of sperm and they have these germ cells,” he said.

“So germ cells are designed also in a way to give us two different tissues as well so we were able to get a germ cell from testes and instruct them to become other tissues.”

Humans will also benefit because the results are transferable to humans said Dr. Rafii.

“It can easily be applied to a human in near future,” he said.

Subjects should not be difficult to find Rafii added.

“If I had end stage heart disease, I would think, take all my testes, all right? So it is a no-brainer,” he said.

The journal Nature has published Dr. Rafii’s research.

While the work is promising it will be some time before the results could be reproduced in humans said Peter Schofield, who is the executive director of the Prince of Wales Medical Research Institute in Sydney.

“I think there’s still quite a bit of experimental work to be done,” he said.

“The mouse experiments used a number of techniques which are possible in mouse embryology but would not in any way be translatable to potential human treatment today.”

“But the important thing is that the experiments showed was that it was possible.”

Creating non-embryonic stem cells carries a high level of interest says Professor Schofield.

“Certainly the comments that came out from the researchers’ labs in the United States perhaps are a little bit over-selling around the potential benefits of adult versus embryonic stem cells,” he said.

“I guess the situation here in Australia is that both of them are now permitted under various strong licensing regimes and the technology that delivers the clinical benefits will obviously be the one that works.”

“This is really important research because it shows that there is another possible way of reprogramming adult stem cells. In the mouse it shows that those cells were able to form important other organs.”

“There’s still a lot of steps before that could be done in a human situation, but the fact that it has been done is both very exciting and offers a lot of promise.”

For men, it is a possible breakthrough that will manifest itself in the future. But women should not be disappointed either says Dr. Rafii. They will also benefit.

“In women also this stem cell exists but the number is very, very low and we hope that eventually we can be able to get these stem cells from their ovaries as well,” he said.

“Also another point – some men can give stem cells to compatible, genetically compatible females so it still can be applied for women as well.”

Thalassemia and Sickle Cell Disease can be Cured with Cord Blood Stem Cells

Umbilical cord blood taken from a compatible sibling can cure children with Thalassemia and Sickle Cell Disease. The report was made by the Children’s Hospital & Research Center Oakland and ViaCell, Inc.

Cord blood from a relative may have advantages over bone marrow transplantation and can be an effective source of stem cells for transplantation in children affected with Sickle Cell Disease and Thalassemia. The research was presented by Dr. Mark Walters, Director of the Blood and Marrow transplant program at Children’s Hospital & Research Center Oakland. Dr. Walters made the presentation at the Sickle Cell Disease Association of America and National Institutes of Health (NIH) 35th Annual Convention.

“Patients with Sickle Cell and Thalassemia often lead debilitating lives,” said Dr. Walters. “Through continued research and transplant success, sibling umbilical cord blood has proven to be effective in curing children of these blood disorders. I expect the use of umbilical cord blood will continue to increase and as we gain more experience using cord blood stem cells in transplant medicine, I believe it could outpace the use of bone marrow in transplant medicine.”

The data presented at the Sickle Cell Disease Association of America and NIH meeting showed outcomes from children treated under The Sibling Connection Program, a directed sibling transplant program implemented by ViaCord and Children’s Hospital Oakland Research Institute (CHORI), the research arm of Children’s Hospital & Research Center Oakland.

More than 100 children have been treated with cord blood thanks to the program. 23 children were transplanted for Thalassemia and 17 were transplanted for Sickle Cell Disease under the Sibling Connection Program. The median age of patients treated for Sickle Cell Disease was 8 years and 5 years for patients treated for Thalassemia.

Clinical advantages over bone marrow have been demonstrated in regards to sibling umbilical cord blood transplantation in young children. A reduction in the common side effect and leading cause of death in transplant medicine, graft-versus-host (GvHD), was also observed. GvHD was observed in six of the Sickle Cell Disease patients, but none of them developed chronic GvHD. As for Thalassemia, none of the patients were observed to have acute or chronic GvHD.

For patients treated for Sickle Cell Disease, the median time to platelet recovery (greater than 20,000 per microliter) and neutrophil recovery (ANC greater than 500 cells per microliter) was 36 days and 18 days respectively.

82% of the patients treated for Sickle Cell Disease survived and is disease-free. For patients treated for Thalassemia, the median time to platelet recovery (greater than 20,000 per microliter) and neutrophil recovery (ANC greater than 500 cells per microliter) was 47 days and 25 days respectively. 91% of the patients treated for Thalassemia are now disease free and 96% of the patients survived.

The Sibling Connection Program in the area of directed transplants for sibling donor umbilical cord blood was formed in 2006 by the combined efforts of CHORI and ViaCell. Units of cord blood that has been collected and processed through the program have treated over 100 children to date. This includes transplants through cord blood stored through CHORI’s Sibling Donor Cord Blood Program and cord blood collected, preserved and stored with ViaCord. If a family has a child diagnosed with a condition that can be treated with a cord blood stem cell transplant and they meet the other requirements of the program, the Sibling Connection Program provides ViaCord’s comprehensive cord blood collection, processing and five years of storage at no cost.

Resulting in the red blood cells being a sickle or crescent shape, Sickle Cell Disease is an inherited blood disorder. Tissue damage is caused when the abnormally shaped cells prevent normal flow of oxygen to tissues by becoming rigid. Anemia, jaundice, frequent infections, and chest pain are among the common symptoms. No universal cure for Sickle Cell Disease currently exists.

Blood transfusions, antibiotics, intravenous fluids, pain management, and even surgery are currently used to treat complications associated with Sickle Cell Disease. Over 80,000 people in the United States have sickle cell anemia and over 2.5 million carry the trait. People of Mediterranean descent and African Americans are the two demographics that Sickle Cell Disease predominantly effects. National Sickle Cell Awareness Month is September.

Umbilical cord blood is an emerging therapeutic treatment option for patients with Thalassemia and Sickle Cell Disease. In 2000, the first cord blood unit was released by ViaCord to treat Sickle Cell Disease. Families who have children affected with Sickle Cell Disease make up 30% of all enrollments in the ViaCord/CHORI Sibling Connection Program.

Hemoglobin is a critical oxygen-carrying protein in red blood cells. The decreased production of hemoglobin is what characterizes Thalassemia which is another hereditary blood disorder. A shortage of red blood cells occurs along with anemia. Lifelong red blood cell transfusions and the resulting complications come with a diagnosis that usually occurs in early childhood. Poor growth, enlarged spleen and liver, anemia, jaundice, and abnormal facial bones are some of the symptoms of the condition. However, the symptoms of Thalassemia due vary depending on the type and severity of the disease. There are approximately 1,000 people are living with Thalassemia in the U.S. and an estimated 2 million people in the United States carry the genetic trait for Thalassemia.

With proven therapeutic effect in treating over 40 diseases, umbilical cord blood is a valuable, non-controversial source of stem cells. Certain blood disorders such as sickle cell anemia, thalassemia and other genetic disorders, bone marrow failure syndromes such as Diamond Blackfan anemia and severe aplastic anemia, and cancers such as Non-Hodgkin’s lymphoma and Acute Lymphoblastic Leukemia (ALL) can be treated. To date, nearly 8,000 cord blood transplants have been performed world wide. A significantly higher survival rate has been observed when umbilical cord blood transplants from a family member, rather than from a non-relative are used.

Stem Cell Clinic to Open in Bermuda

Bermuda Sun

Because our laws have failed to keep pace with medical advances, a stem cell clinic will be opening without obtaining permission from a regulatory body. The clinic will be run by Dr. Ewart Brown and his wife Wanda.

However, Canada, the U.S., and the U.K. don’t normally cater to this manner of doing business.

Authoritative bodies such as the Human Fertilization and Embryology Authority and the Medicine and Healthcare Products Regulatory Agency in the U.K., the Food and Drug Administration in the U.S., and the Stem Cell Oversight Committee in Canada regulate and oversee all the treatment centers and research institutes that do experimental procedures in those respective countries. The system closely monitors all aspects of stem cell research and treatment.

It was the response to developments and ethical issues that have arisen in the field of stem cell research that prompted the establishment of Canada’s Stem Cell Oversight Committee and the Human Fertilization Authority in the U.K.

In partnership with San-Diego based firm Stemedica Cell Technologies, the stem cell clinic will open at Winterhaven in Smith’s. Dr. Brown, a physician, and his wife Wanda went public in July with their plans.

The soon to be established Brown-Darrell clinic will only use adult stem cells and avoid the controversial embryonic cells.

The Bermuda Health Council began overseeing all health care after the government passed a law in 2004.

By law, all health care service providers must have a license if they are seeking to go into business.

But it is not known when the regulations will be ready to be reviewed by Cabinet since the Bermuda Health Council is still in the process of writing them.

Health Council CEO Anthony Richardson told the Bermuda Sun, in a written statement: “The Bermuda Health Council is governed by the Bermuda Health Council Act 2004. One of the functions of the Council is to regulate health service providers. At this time, we are in the process of preparing recommended regulations for the Minister of Health. Consequently, the Council does not currently issue licenses.”

The National Institutes for Health in the U.S. and the U.K. Stem Cell Initiative make it clear on their websites that significant hurdles need to be overcome before treatment becomes a reality. They also say that the use of stem cells to treat diseases such as Parkinson’s and Alzheimer’s holds great promise. But other than for bone marrow transplants and skin grafts, treatment using stem cells is still in the experimental stage.

Before they are allowed to carry out trials on humans, scientists have to get the green light from the FDA or its U.K. counterpart. This is the case even if the scientist has achieved promising results in animal models.

Dr. Ben Goldacre, who writes a science column for The Guardian and is familiar with the issues raised in our stories today, told the Bermuda Sun: “A stem cell laboratory doing meaningful research is a major scientific undertaking.”

The Ministry of Health currently issues licenses to health care providers, but contacting them for comment has been nearly impossible. The rest of the medical community has been equally difficult to reach.

the Brown-Darrell clinic will need a license to operate said Chief Medical Officer Dr. John Cann , through a Government spokeswoman. But no details were given.

Rather than assessing what procedures are carried out, the license that the Brown-Darrell clinic would require would be the same as for any medical practice and would address health and safety issues as they relate to the physical set-up of the premises according to a health professional familiar with current legislation.

In the absence of oversight from an independent committee, doctors have privately stated that they are sceptical about procedures that would be carried out at the Brown-Darrell clinic. However, no public statements on this matter were made.

One doctor told the Bermuda Sun: “You just can’t open up shop and say: ‘I’m going to cure diseases with stem cells’. If we do, then we’re a third world country.”

The ramifications of the venture as a group has not been discussed by physicians.

The silence from the medical community is “appalling” according to a second doctor the Bermuda Sun spoke with.

Neither wanted their names attached to their comments.

The Bermuda Sun was told that the council would have no jurisdiction over the procedures that would be done at the clinic if only research is carried out stated Dr. Delmont Simmons, chairman of the Bermuda Medical Council, which issues licenses to doctors that allows them to practice. A license will need to be obtained from the council if doctors plan on treating patients he added.

Efforts to get a response from the Browns were unsuccessful.

Kendaree Burgess-Fairn, spokeswoman for the Brown-Darrell Clinic, said the Browns have said all they want to say about the clinic at this stage when the Bermuda Sun sought comment several weeks ago and last Friday.

The clinic should be opening this fall and the Browns plan to operate it as a private venture.

While research would be the initial priority, eventually the clinic would treat one or two patients with diseases such as Alzheimer’s and Parkinson’s per week said Mrs. Brown in July, who is to be the clinic’s consulting CEO.

She said the clinic will host “advanced research in the use of adult stem cells for human treatment.”

She was also quoted as saying: “It is our hope and intention that what we do at Brown-Darrell will help lay the groundwork for the treatment of patients around the world who, without stem cell treatment, have no hope for a normal life.”

“We believe that we will significantly improve the quality of life of those patients we treat, and that we will contribute to the research being conducted in this field that will some day make stem cell treatment available to all those who need it.”

Stemedica says on its website that its physicians have “conducted stem cell transplantation with over 1,500 human subjects.”

Stemedica has a ‘clinical trials’ heading on its website, but it merely lists website addresses such as the National Institutes for Health and the one set up by Parkinson’s sufferer, actor Michael J. Fox.

Russian-trained scientists, most of whom are now based in the U.S., and physicians and American businessmen have teamed up to form Stemedica. They have been involved with past lucrative ventures in the industries of nutritional products, a top-selling laser that’s used in cosmetic procedures, and bottled water.

Having worked primarily as an inventor in the U.S., Stemedica’s president and chief medical officer Dr. Nicholai Tankovich is a Russian trained physician and physicist.

He made $35.3 million for the first six months of this year and $57.5 million in 2006 after inventing the Fraxel laser product.

The Stemedica website describes a “world-class team” when pointing out their 12 members in lower management.

Dr. Tankovich is among the group, whose members, again according to the website, are located in Centers of Excellence in San Diego and Palo Alto, in California, and Eastern Europe and “are directed towards treating diseases that have no cure.”

Nine of the 12 are physicians. California Medical Board spokeswomen Candis Cohen and Debbie Nelson confirmed that none of the nine – Dr. Tankovich, Nikolay Mironov, Illiya Mironov, Sergey Ivanov, Narik Markchyan, Katherine Chentsova, Rosa Gundorova, Natalie Gavrilova and Vadim Repin – have a license to practice medicine in the state of California. Neither does Dr. Kharazi, Stemedica’s vice president of medical research. We should make it clear that there is no suggestion that any of the physicians are practicing medicine in California without a license, or that their professional credentials are in doubt.

Stem Cell Therapy Market to Explode by 2017

A recent report conducted by the Millennium Research Group (MRG) has determined that the industry is set to explode. Their detailed analysis, US Markets for Stem Cell Therapies 2007, determined that as products are approved in the U.S., the market will grow rapidly despite its current state of infancy. By 2017, almost 90 products are expected to be available, despite the fact that only two are on the market today.

Stem cells have the potential to cure diseases that are currently incurable and can provide lasting treatments for chronic disorders. This is due to their regenerative capabilities. Blackstone Medical’s Trinity and US-Osiris Therapeutics’ Osteocel were the only two products available in the U.S. in 2007. Both are orthopedic products and over $25 million in revenues were earned by these therapies alone in 2007.

Public acceptance, regulatory approval, and the success of clinical trials will determine how the rest of the U.S. market for stem cell therapies develops. Between 2009 and 2013, the first tissue and organ, neurological, diabetes, and cardiovascular stem cell therapies are expected to enter the market. These products will have vast market potential and offer hope to patients by opening up a new realm of treatable disorders.

“This market has almost everything going its way”, says Chris Schutz, senior analyst at MRG. “The big question mark however is the political and public support. The prevalence of potentially treatable disorders, unmet medical needs, rising health care costs, growth in the aging population, and the success of the first stem cell therapy products are all factors that will drive this market upward through 2017.”

Osiris Therapeutics, Blackstone Medical, Geron, Harvest Technologies, Advanced Cell Technologies, Aastrom Biosciences, Cytori Therapeutics, International Stem Cell Corporation, and Arteriocyte, are the names mentioned in the US Markets for Stem Cell Therapies 2007 report as companies offering or developing products for the stem cell therapy market.

Derived from highly proliferative tissues, stem cells are primal cells. In the human body, every organ, cell, and tissue is created by these stem cells. Cancer, diabetes, neurological disease, orthopedic degenerative disease, retinal disease, cardiovascular disease, and other chronic and autoimmune disorders can potentially be cured by stem cells because of their universality and ability to repair or replace damaged tissue.

T-reg Cells Derived from Cord Blood Used in First Clinical Trial for Leukemia

In order to decrease the risk of immune reactions common in patients undergoing blood and marrow transplantation researchers have taken steps to determine the safety and optimal dose of T regulatory cells (T-regs) at the University of Minnesota.

The groundbreaking clinical trial is being conducted with the hope that it will offer a potential new paradigm for treating autoimmune diseases as well as improve overall survival rates for blood cancer patients.

“Toward our quest of making transplants even safer for adults and children with leukemia, lymphoma, multiple myeloma, and other blood and marrow disorders, we are exploring the possibility of using T-regs to enhance the rate of blood and marrow recovery and reduce the risks of graft-versus-host disease, a complication that affects more than 60 percent of patients,” said Claudio Brunstein, M.D., principal investigator of the study.

Normally responsible for regulating the body’s immune responses, T-regs are a type of lymphocyte or white blood cell. Helping to ward off life-threatening graft-versus-host-disease (GVHD), donor T-regs may suppress the recipient’s immune system so that the healthy donor’s blood-forming stem cells and immune cells can grow in transplant cases. When donated cells attack the body of the transplant recipient it is referred to as GVHD. Following transplant, GVHD is responsible for one-third of the deaths.

The risk of GVHD decreases and the chance of blood and marrow recovery increases when T-regs are infused after transplant. This has been proven by researchers using animal models.

“Once we identified that T-regs were highly effective in mouse models, we then spent three years finding ways to make this therapy valuable for transplant patients and potentially useful for patients with autoimmune diseases,” said Bruce Blazar, M.D., director of the Center for Translational Medicine at the University.

Since they are easier to expand in culture prior to treatment and occur in higher frequency than what is typically found in most adults, the T-regs in this study are isolated from umbilical cord blood (blood collected from the placenta or afterbirth after the birth of a child). This unique use of umbilical cord blood derived T-regs marks a world first for human clinical trials.

Using patients who are undergoing a double umbilical cord blood transplant for bone marrow failure, leukemia, or other blood cancer; this trial is designed to find the highest possible safe dose of T-regs in these immune suppressed patients. There should be no acute side effects with the T-regs according to researchers who have observed similar results already in animal models.

T-regs will be a powerful therapy to enhance engraftment in transplant patients and prevent GVHD if the data in humans mimics animal models. Conditions such as multiple sclerosis, type I diabetes, and other autoimmune diseases will be treated with the T-regs to test for effectiveness once initial efficacy and safety data is known. The cell may help prevent disease progression if T-regs are transplanted early in the life of the disease hypothesized university researchers.

“This is an exciting time. In the near future, I anticipate being able to combine immune cell populations, like T-regs, that stop immune reactions responsible for autoimmune diseases like diabetes, and immune responses to stem cell infusion given to repair already damaged tissues. This brings great hope not only for adults and children with cancer but many other diseases as well. At the close of this clinical trial, we hope to go right to our first clinical trial with T-regulatory cells in the treatment of newly diagnosed diabetes,” said John E. Wagner, M.D., director of the pediatric hematology-oncology and blood and marrow transplantation program at the University of Minnesota.

The Children’s Cancer Research Fund, the National Marrow Donor Program, the Leukemia and Lymphoma Society, the National Institute of Allergy and Infectious Diseases, the National Heart Lung and Blood Institute, the National Cancer Institute, and the National Institutes of Health are funding the study.
