Dr Changfa Guo, Professor Chunsheng Wang and their co-investigators from Zhongshan hospital Fudan University, Shanghai, China have established a novel hyperbranched poly(amidoamine) (hPAMAM) nanoparticle based hypoxia regulated vascular endothelial growth factor (HRE-VEGF) gene therapy strategy which is an excellent substitute for the current expensive and uncontrollable VEGF gene delivery system. This discovery, reported in the June 2012 issue of Experimental Biology and Medicine, provides an economical, feasible and biocompatible gene therapy strategy for cardiac repair.

Transplantation of VEGF gene manipulated mesenchymal stem cells (MSCs) has been proposed as a promising therapeutic method for cardiac repair after myocardium infarction. However, the gene delivery system, including the VEGF gene and delivery vehicle, needs to be optimized. On one hand, long-term and uncontrollable VEGF over-expression in vivo has been observed to lead to hemangioma formation instead of functional vessels in animal models. On the other hand, though non-viral gene vector can circumvent the limitations of virus, drawbacks of the current non-viral vectors, such as complex synthesis procedure, limited transfection efficiency and high cytotoxicity, still needs to be overcome.

Co-investigators, Drs. Kai Zhu and Hao Lai, said "Hypoxia response elements were inserted into the promoter region of VEGF gene to form HRE-VEGF, which provided a safer alternative to the conventionally available VEGF gene". "The HRE-VEGF up-regulates gene expression under hypoxic conditions caused by ischemic myocardium and turns it off under normoxia condition when the regional oxygen supply is adequate."

The hPAMAM nanoparticles, which exhibit high gene transfection efficiency and low cytotoxicity during the gene delivery process, can be synthesized by a simpler and more economical one-step/pot polymerization technique. Drs. Zhu and Lai, said "Using the hPAMAM based gene delivery approach, our published and unpublished results explicitly demonstrated that it was an economical, effective and biocompatible gene delivery vehicle".

Dr Guo concluded that "Treatment with hPAMAM-HRE-VEGF transfected MSCs after myocardium infarction improved the myocardial VEGF level, which improved graft MSC survival, increased neovascularization and ultimately improved heart function. And this novel VEGF gene delivery system may have clinical relevance for tissue repair in other ischemic diseases".

Dr. Steve Goodman, Editor-in-Chief of Experimental Biology and Medicine said "Guo and colleagues have provided an exciting new nanoparticle based gene therapy for cardiac repair. This novel approach has great promise for repair of the heart after myocardial infarction."

An economical, effective and biocompatible gene therapy strategy promotes cardiac repair

SACRAMENTO, CA. - A drug used to treat diabetes encourages the brain to grow and repair itself, afinding with far-reaching implications for the treatment of Alzheimers and brain injury, a new study published in Cell: Stem Cell reports.

The widely used diabetes drug metformin comes with the unexpected side effect of causing the growth of new neurons in the brain and makes mice smarter, the July 6th issue of Cell Stem Cell, a Cell Press publication, said. The study has potentially wide-reaching implications for the treatment of Alzheimers in humans and brain related injury.

The discovery has important implications for brain repair because it works not by introducing new stem cells but rather by spurring those that are already present into action, said the study's lead author Freda Miller of the University of Toronto-affiliated Hospital for Sick Children. And since the drug is already so widely used and so safe it means doctors could quickly begin using the drug for brain therapy treatment.

Earlier work by Miller's team highlighted a pathway known as aPKC-CBP for its essential role in telling neural stem cells where and when to differentiate into mature neurons, the report said. Other researchers had found before them that the same pathway is important for the metabolic effects of the drug metformin, but in liver cells.

"We put two and two together," Miller says. If metformin activates the CBP pathway in the liver, they thought, maybe it could also do that in neural stem cells of the brain to encourage brain repairm, he said.

Mice taking metformin not only showed an increase in the birth of new neurons, but they proved to become smarter by being better able to learn the location of a hidden platform in a standard maze test of spatial learning. The new evidence lends support to that promising idea in both mouse brains and human cells.

While it remains to be seen whether the very popular diabetes drug might already be serving as a brain booster for those who are now taking it, there are early hints the drug may have cognitive benefits for people with Alzheimer's disease. Scientists had speculated those improvements were the result of better diabetes control, Miller says, but it now appears that metformin may improve Alzheimer's symptoms by enhancing brain repair.

Miller says they now hope to test whether metformin might help repair the brains of those who have suffered brain injury due to trauma or radiation therapies for cancer.

Diabetes drug helps brain growth, makes mice smarter

ScienceDaily (July 5, 2012) The widely used diabetes drug metformin comes with a rather unexpected and alluring side effect: it encourages the growth of new neurons in the brain. The study reported in the July 6th issue of Cell Stem Cell, a Cell Press publication, also finds that those neural effects of the drug also make mice smarter.

The discovery is an important step toward therapies that aim to repair the brain not by introducing new stem cells but rather by spurring those that are already present into action, says the study's lead author Freda Miller of the University of Toronto-affiliated Hospital for Sick Children. The fact that it's a drug that is so widely used and so safe makes the news all that much better.

Earlier work by Miller's team highlighted a pathway known as aPKC-CBP for its essential role in telling neural stem cells where and when to differentiate into mature neurons. As it happened, others had found before them that the same pathway is important for the metabolic effects of the drug metformin, but in liver cells.

"We put two and two together," Miller says. If metformin activates the CBP pathway in the liver, they thought, maybe it could also do that in neural stem cells of the brain to encourage brain repair.

Diabetes drug makes brain cells grow

(PRWEB) July 05, 2012

Researchers at Adelaide University have developed a potential therapy for stroke victims utilizing dental stem cells to regenerate damaged brain cells.

The study involved the use of human dental pulp stem cells in rats suffering from post- stroke symptoms. The stem cells were transplanted into the damaged brains of the rats with the rats showing significant improvement in brain function, motor skills and cognitive abilities within several weeks. The therapy poses a new possibility for patients who have suffered a stroke. Patients will be able to use stem cells extracted from their own teeth to regenerate damaged brain tissue. The use of autologous stem cells eliminates the risk of rejection and the need for immune-suppression drugs and results in a more positive outcome. The research is so promising that the researchers hope to begin clinical trials within three to four years.

The research is another example of the inherent plasticity of dental stem cells, i.e. their ability to differentiate into a wide range of tissue types that may be utilized to treat a broad array of disease, trauma and injury. Banking your own valuable dental stem cells for use in emerging regenerative therapies is both convenient and affordable and as easy as a trip to the dentists.

Stem cell research is gaining headway, but is still controversial. Scientists hope that a new discovery regarding stem cells from amniotic fluid will pave the way to an alternative option. A collaborative group of researchers recently discovered that stem cells in amniotic fluid can be changed into a more flexible state, which could possibly open another option to embryonic stem cells.

The study was recently published in the journal Molecular Therapy and it described how a team of investigators from Imperial College London and the UCL Institute of Child Health were successful in reprogramming amniotic fluids without introducing extra genes. Based on the findings, the researchers believe that stem cells from amniotic fluid could be held in banks for therapy or research purposes. Amniotic fluid, which surrounds and feeds the fetus, can be taken from the mothers abdomen with a needle during amniocentesis and has stem cells from the fetus. These stem cells have more limitations in developing into other cells as compared to embryonic stem cells.

These cells have a wide range of potential applications in treatments and in research. We are particularly interested in exploring their use in genetic diseases diagnosed early in life or other diseases such as cerebral palsy, noted Dr. Pascale Guillot, a representative of the Department of Surgery and Cancer at Imperial College London, in a prepared statement.

In the project, the scientists utilized stem cells that were donated from mothers who were undergoing amniocentesis; amniocentesis has been used in the past in testing for genetic diseases. The cells were then grown on a gelatinous protein mixture in a lab and reprogrammed into a lower state by adding the drug valproic acid to the culture medium. The results showed that the reprogrammed cells had traits like those found in embryonic stem cells; embryonic stem cells have pluripotency, which means they have the ability to develop into any cell type found in the body. In particular, the reprogrammed cells from the amniotic fluid were able to develop into functioning cells like bone, liver, and nerve cells. The cells were also able to stay pluripotent after they were frozen and rethawed.

Amniotic fluid stem cells are intermediate between embryonic stem cells and adult stem cells. They have some potential to develop into different cell types but they are not pluripotent. Weve shown that they can revert to being pluripotent just by adding a chemical reagent that modifies the configuration of the DNA so that genes that are expressed in the embryo get switched back on, explained Guillot in the statement.

The findings from the project showed that stem cells from amniotic fluid can possibly be used in treatments for a number of diseases, disease research, and drug screenings. Researchers are positive about the alternative to embryonic stem cells, as it there is a limited number of donor embryos available. The study by Guillot and his colleagues shows that it is possible to have pluripotency in human cells without introducing foreign genetic material into the cells.

This study confirms that amniotic fluid is a good source of stem cells. The advantages of generating pluripotent cells without any genetic manipulation make them more likely to be used for therapy, remarked Dr. Paolo De Coppi, a member of the UCL Institute of Child Health who led the research with Guillot, in the statement. At GOSH we have focused on building organs and tissues for the repair of congenital malformations, which are usually diagnosed during pregnancy. Finding the way of generating pluripotent cells from the fluid that surround the fetus in the womb move us one step further in the this direction.

The study is funded by the Genesis Research Trust, the Henry Smith Charity, and the Action Medical Research.

Stem Cells Extracted From Amniotic Fluid

REDWOOD CITY, Calif.--(BUSINESS WIRE)--

OncoMed Pharmaceuticals, Inc., a clinical-stage company developing novel therapeutics that target cancer stem cells (CSCs), or tumor-initiating cells, today announced that Proceedings of the National Academy of Sciences of the United States of America (PNAS) July 2, 2012 PNAS Early Edition has published online OncoMed data demonstrating the potent anti-cancer activity of OMP-18R5, the companys first Wnt pathway product candidate, in multiple preclinical human tumor models. OMP-18R5 is currently in Phase 1 clinical testing.

OMP-18R5 is, we believe, the first therapeutic antibody to enter clinical trials that specifically inhibits the Wnt pathway, an important pathway in cancer. Our research published in PNAS suggests that inhibiting the Wnt pathway within tumors has the potential to improve treatment for multiple cancers, said Austin Gurney, Ph.D., Senior Vice President, Molecular and Cellular Biology of OncoMed Pharmaceuticals and a co-author of the paper. OMP-18R5 has demonstrated the remarkable ability to drive the differentiation of tumor cells in preclinical models. Tumors become less tumorigenic.

The Wnt/beta-catenin pathway, which signals through the Frizzled (Fzd) receptor family and several co-receptors, has long been implicated in cancer. OncoMed researchers identified a novel therapeutic approach to targeting the Wnt pathway with a monoclonal antibody. OMP-18R5, initially identified by binding to Frizzled 7, interacts with key Fzd receptors through a conserved epitope within the extracellular domain and thereby inhibits canonical Wnt signaling induced by multiple Wnt family members. In xenograft studies with minimally passaged human tumors, OMP-18R5 inhibits the growth of a range of tumor types and exhibits synergistic activity with standard-of-care chemotherapeutic agents. These data are published in current edition of PNAS in an article titled Wnt Pathway Inhibition via the Targeting of Frizzled Receptors Results in Decreased Growth and Tumorigenicity of Human Tumors.

Paul Hastings, President and Chief Executive Officer of OncoMed Pharmaceuticals, said, OMP-18R5 is among a rich pipeline of therapeutic candidates discovered by OncoMed that are now in clinical trials. We look forward to reporting results from our initial trials as this product advances through the clinic.

About OMP-18R5

OMP-18R5 is a monoclonal antibody optimized to block a key signaling pathway in cancer. Specifically, OMP-18R5 selectively targets Frizzled receptors, activators of Wnt signaling. OMP-18R5 treatment exhibits broad anti-tumor activity in preclinical models. OMP-18R5 is currently in a Phase 1 clinical trial in patients with advanced solid tumors. This trial will assess safety, pharmacokinetics, and provide initial indications of anti-tumor efficacy and the effects of OMP-18R5 on Wnt pathway biomarkers. OMP-18R5 is part of OncoMeds collaboration with Bayer Pharma AG.

PNAS Publishes OncoMed Data Demonstrating Potent Anti-Cancer Activity for Novel Wnt Pathway Antibody OMP-18R5

ScienceDaily (July 3, 2012) Stem cells found in amniotic fluid can be transformed into a more versatile state similar to embryonic stem cells, according to a study published July 3 in the journal Molecular Therapy. Scientists from Imperial College London and the UCL Institute of Child Health succeeded in reprogramming amniotic fluid cells without having to introduce extra genes. The findings raise the possibility that stem cells derived from donated amniotic fluid could be stored in banks and used for therapies and in research, providing a viable alternative to the limited embryonic stem cells currently available.

Amniotic fluid surrounds and nourishes the fetus in the womb. It can be extracted through the mother's abdomen using a needle in a process called amniocentesis, which is sometimes used to test for genetic diseases. The fluid contains stem cells that come from the fetus. These cells have a more limited capacity to develop into different cell types than stem cells in the embryo.

The researchers used stem cells from amniotic fluid donated by mothers undergoing amniocentesis for other purposes during the first trimester of pregnancy. The cells were grown on a gelatinous protein mixture in the lab and reprogrammed into a more primitive state by adding a drug called valproic acid to the culture medium. An extensive set of tests found that these reprogrammed cells have characteristics very similar to embryonic stem cells, which are capable of developing into any cell type in the body -- a property known as pluripotency.

Even after growing in culture for some time, the reprogrammed cells were able to develop into functioning cells of many different types, including liver, bone and nerve cells. They also maintained their pluripotency even after being frozen and rethawed.

The results suggest that stem cells derived from amniotic fluid could be used in treatments for a wide range of diseases. Donated cells could be stored in banks and used in treatments, as well as in disease research and drug screening. A previous study estimated that cells from 150 donors would provide a match for 38% of the population.

Alternatives to embryonic stem cells are keenly sought because of ethical concerns and limited availability of donor embryos. Previous research has shown that it is possible to make adult cells become pluripotent by introducing extra genes into the cells, often using viruses. However, the efficiency of the reprogramming is very low and there is a risk of problems such as tumours caused by disrupting the DNA. The new study is the first to induce pluripotency in human cells without using foreign genetic material. The pluripotent cells derived from amniotic fluid also showed some traits associated with embryonic stem cells that have not been found in induced pluripotent stem cells from other sources.

Amniocentesis is associated with a small risk of causing a miscarriage, estimated to be about one in 100.

Dr Pascale Guillot, from the Department of Surgery and Cancer at Imperial, said: "Amniotic fluid stem cells are intermediate between embryonic stem cells and adult stem cells. They have some potential to develop into different cell types but they are not pluripotent. We've shown that they can revert to being pluripotent just by adding a chemical reagent that modifies the configuration of the DNA so that genes that are expressed in the embryo get switched back on.

Amniotic fluid yields alternatives to embryonic stem cells

ScienceDaily (July 3, 2012) searchers from the University of Maryland School of Maryland report promising results from using adult stem cells from bone marrow in mice to help create tissue cells of other organs, such as the heart, brain and pancreas -- a scientific step they hope may lead to potential new ways to replace cells lost in diseases such as diabetes, Parkinson's or Alzheimer's.

The research in collaboration with the University of Paris Descartes is published online in the June 29, 2012 edition of Comptes Rendus Biologies, a publication of the French Academy of Sciences.

"Finding stem cells capable of restoring function to different damaged organs would be the Holy Grail of tissue engineering," says lead author David Trisler, PhD, assistant professor of neurology at the University of Maryland School of Medicine.

He adds, "This research takes us another step in that process by identifying the potential of these adult bone marrow cells, or a subset of them known as CD34+ bone marrow cells, to be 'multipotent,' meaning they could transform and function as the normal cells in several different organs."

University of Maryland researchers previously developed a special culturing system to collect a select sample of these adult stem cells in bone marrow, which normally makes red and white blood cells and immune cells. In this project, the team followed a widely recognized study model, used to prove the multipotency of embryonic stem cells, to prove that these bone marrow stem cells could make more than just blood cells. The investigators also found that the CD34+ cells had a limited lifespan and did not produce teratomas, tumors that sometimes form with the use of embryonic stem cells and adult stem cells cultivated from other methods that require some genetic manipulation.

"When taken at an early stage, we found that the CD34+ cells exhibited similar multipotent capabilities as embryonic stem cells, which have been shown to be the most flexible and versatile. Because these CD34+ cells already exist in normal bone marrow, they offer a vast source for potential cell replacement therapy, particularly because they come from a person's own body, eliminating the need to suppress the immune system, which is sometimes required when using adults stem cells derived from other sources," explains Paul Fishman, MD, PhD, professor of neurology at the University of Maryland School of Medicine.

The researchers say that proving the potential of these adult bone marrow stem cells opens new possibilities for scientific exploration, but that more research will be needed to see how this science can be translated to humans.

Bacterin Receives Letter From NYSE MKT LLC Regarding Timely Notice of Record Date for 2012 Annual Meeting of ...

Tuesday, July 03 16:25:12

Ireland has the capacity to be an international centre for commercialisation in the field of regenerative medicine, delegates at an international stem cell conference in NUI Galway heard today.

Reflecting this potential, new Irish company Orbsen Therapeutics is developing proprietary technologies designed to isolate stem cells. The NUI Galway spin-out is targeting the rapidly maturing and expanding regenerative medicine market, which is expected to grow to $118 billion next year.

Frank Barry is Professor of Cellular Therapy at NUI Galway, Director of Orbsen Therapeutics, and organiser of the Mesenchymal Stem Cell Conference, which opened yesterday.

Mesenchymal stem cells (MSCs) are a type of adult stem cell, and this event brings together the world's leading scientists in the field to discuss their latest ideas and findings. This is the first major stem cell conference to take place in Ireland, and is looking at all aspects of adult stem cells, from basic biology to manufacturing to clinical trials and therapeutics.

Stem cells hold great promise as an alternative to drugs and surgical procedures for treating a wide range of medical conditions including heart disease, arterial disease of the limbs, diabetes complications, arthritis and other inflammatory conditions. The treatment potential of stem cells is linked to their natural capacity to dampen inflammation and promote healing, repair and regeneration of damaged tissues.

According to Professor Barry: "Ireland has a strong research base in adult stem cell therapy and has the capcacity for advanced stem cell bioprocessing. There is huge potential in this market and we anticipate that there will be extraordinary growth over the next 5-10 years. There are currently over 400 regenerative medicine products on the market with many more in development." Orbsen Therapeutics has developed a clear pipeline of clinical indications which they hope, using their proprietary technologies, to bring through to clinical trial over the coming years. These include osteoarthritis, acute lung injury syndrome, diabetic foot ulcer, critical limb ischemia and others."

"Combining the utility, novelty and the value of its technologies, Orbsen is well placed to take advantage of the many opportunities in this fast moving and important emerging market", said Brian Molloy, CEO of Orbsen Theraepeutics."

Orbsen Therapeutics Limited was formed as a spin out company to develop and commercialise new intellectual property built up by researchers at the SFI-funded Regenerative Medicine Institute (REMEDI) at NUI Galway.

Scientists at NUI Galway are investigating how adult stems cells might be used to develop new treatments for vascular disease, osteoarthritis and lung injury. The University has become a leading centre of translational research in adult stem cells involving its National Centre for Biomedical Engineering Science (NCBES) and REMEDI.

SHENZHEN, China, July 3, 2012 /PRNewswire-Asia/-- A study conducted by Beike Biotechnology Company (http://www.beikebiotech.com) in conjunction with physicians and researchers at two Chinese hospitals, documents the effectiveness of cord blood-derived stem cells in treating primary biliary cirrhosis (PBC). The study, which was published in the April 2012 issue of the Stem Cell Discovery, was the first of its kind. Researchers noted that additional clinical trials would be required before stem cells can become an accepted therapy for liver cirrhosis.

Prof. Jin-hui Yang, Director of the Department of Hepatology in the 2nd Affiliated Hospital of Kunming Medical College stated, "Given the severity of liver cirrhosis and its related conditions, and the limited number of options available to treat those who suffer from it, this finding represents an important, potentially significant breakthrough."

PBC is a chronic, progressive liver disease that leads eventually to fibrosis and cirrhosis of the liver. It affects 1 in 1,000 women over the age of 40.Approximately one-third of those who suffer from PBC and its related conditions do not respond well to Ursodeoxycholic acid (UDCA) treatment, which is the only currently FDA-approved standard medical treatment for the condition. Many of those patients ultimately require liver transplantation.

Beike Chairman, Dr. Sean Hu, commented, "With a growing body of research that demonstrates the effectiveness of cord blood-derived stem cell therapies in treating a broad range of chronic conditions, this latest study is a milestone in the continuing effort to gain broad acceptance and recognition of regenerative medicine as a mainstream treatment option.We look forward to conducting more comprehensive clinical trials to attempt to validate the positive outcomes we have already observed."

The case study reported in the Stem Cell Discovery involved a 58 year old woman suffering from PBC who developed an incarcerated hernia and uncontrolled hydrothorax after undergoing UDCA treatment.One week after completing two stem cell transplantations with no observed adverse effects, the patient showed improvement in both liver function and in her general condition. She was released from the hospital but continued to receive twice-daily UDCA treatments. Six months after her discharge, doctors observed continued improvements in her liver function and overall condition.

Ireland has the capacity to be an international centre for commercialisation in the field of regenerative medicine, delegates at an international stem cell conference in NUI Galway heard today.

Reflecting this potential, new Irish company Orbsen Therapeutics is developing proprietary technologies designed to isolate stem cells. The NUI Galway spin-out is targeting the rapidly maturing and expanding regenerative medicine market, which is expected to grow to $118 billion next year.

Frank Barry is Professor of Cellular Therapy at NUI Galway, Director of Orbsen Therapeutics, and organiser of the Mesenchymal Stem Cell Conference, which opened yesterday.

Mesenchymal stem cells (MSCs) are a type of adult stem cell, and this event brings together the world's leading scientists in the field to discuss their latest ideas and findings. This is the first major stem cell conference to take place in Ireland, and is looking at all aspects of adult stem cells, from basic biology to manufacturing to clinical trials and therapeutics.

Stem cells hold great promise as an alternative to drugs and surgical procedures for treating a wide range of medical conditions including heart disease, arterial disease of the limbs, diabetes complications, arthritis and other inflammatory conditions. The treatment potential of stem cells is linked to their natural capacity to dampen inflammation and promote healing, repair and regeneration of damaged tissues.

According to Professor Barry: "Ireland has a strong research base in adult stem cell therapy and has the capcacity for advanced stem cell bioprocessing. There is huge potential in this market and we anticipate that there will be extraordinary growth over the next 5-10 years. There are currently over 400 regenerative medicine products on the market with many more in development." Orbsen Therapeutics has developed a clear pipeline of clinical indications which they hope, using their proprietary technologies, to bring through to clinical trial over the coming years. These include osteoarthritis, acute lung injury syndrome, diabetic foot ulcer, critical limb ischemia and others."

"Combining the utility, novelty and the value of its technologies, Orbsen is well placed to take advantage of the many opportunities in this fast moving and important emerging market", said Brian Molloy, CEO of Orbsen Theraepeutics."

Orbsen Therapeutics Limited was formed as a spin out company to develop and commercialise new intellectual property built up by researchers at the SFI-funded Regenerative Medicine Institute (REMEDI) at NUI Galway.

Scientists at NUI Galway are investigating how adult stems cells might be used to develop new treatments for vascular disease, osteoarthritis and lung injury. The University has become a leading centre of translational research in adult stem cells involving its National Centre for Biomedical Engineering Science (NCBES) and REMEDI.

SHENZHEN, China, July 3, 2012 /PRNewswire-Asia/-- A study conducted by Beike Biotechnology Company (http://www.beikebiotech.com) in conjunction with physicians and researchers at two Chinese hospitals, documents the effectiveness of cord blood-derived stem cells in treating primary biliary cirrhosis (PBC). The study, which was published in the April 2012 issue of the Stem Cell Discovery, was the first of its kind. Researchers noted that additional clinical trials would be required before stem cells can become an accepted therapy for liver cirrhosis.

Prof. Jin-hui Yang, Director of the Department of Hepatology in the 2nd Affiliated Hospital of Kunming Medical College stated, "Given the severity of liver cirrhosis and its related conditions, and the limited number of options available to treat those who suffer from it, this finding represents an important, potentially significant breakthrough."

PBC is a chronic, progressive liver disease that leads eventually to fibrosis and cirrhosis of the liver. It affects 1 in 1,000 women over the age of 40.Approximately one-third of those who suffer from PBC and its related conditions do not respond well to Ursodeoxycholic acid (UDCA) treatment, which is the only currently FDA-approved standard medical treatment for the condition. Many of those patients ultimately require liver transplantation.

Beike Chairman, Dr. Sean Hu, commented, "With a growing body of research that demonstrates the effectiveness of cord blood-derived stem cell therapies in treating a broad range of chronic conditions, this latest study is a milestone in the continuing effort to gain broad acceptance and recognition of regenerative medicine as a mainstream treatment option.We look forward to conducting more comprehensive clinical trials to attempt to validate the positive outcomes we have already observed."

The case study reported in the Stem Cell Discovery involved a 58 year old woman suffering from PBC who developed an incarcerated hernia and uncontrolled hydrothorax after undergoing UDCA treatment.One week after completing two stem cell transplantations with no observed adverse effects, the patient showed improvement in both liver function and in her general condition. She was released from the hospital but continued to receive twice-daily UDCA treatments. Six months after her discharge, doctors observed continued improvements in her liver function and overall condition.

To review the full text of the published study, please visit: http://www.scirp.org/journal/PaperInformation.aspx?paperID=18710. Study authors included physicians and researchers from the 2nd Affiliated Hospital of Kunming Medical College, Beike Biotechnology Company, and the Yunnan Provincial 1st People's Hospital in Kunming, China.

07/03/2012 . (TMZ) Mel Gibson THREATENED his own 78-year-old step-mom ... SPIT IN HER FACE ... and sabotaged her marriage ... this according to legal docs filed by the woman and obtained by TMZ.

Teddy Joye Hicks Gibson -- who married Mel's father Hutton Gibson in 2001 -- has filed for a restraining order against Mel ... claiming he exploded on her several times and now she fears for her safety.

In the docs, Joye claims Mel and his sister Maura hate her guts ... because she doesn't approve of the controversial medical treatments they've been pressuring Hutton to undergo to treat his various ailments.

In the docs, filed by attorney Brian J. Kramer, Joye describes several outbursts in detail:

October 2011 -- Mel screams at Joye because Joye does not approve of "experimental Ozone treatments" Hutton was undergoing for an undisclosed illness.

"Mel began yelling and saying, 'f*ck this and f*ck that' while leveling other extremely offensive language at me."

Joye claims Mel warned her "not to f*ck with [Hutton's] treatments in any way."

January 2012 -- While visiting Hutton in the hospital, Joye claims she said something that set Mel off ... and "Mel got up, looking wild and began yelling at me in a very loud and terrifying voice."

"Mel was so upset and screaming so fiercely that I could see his face turn red."

March 2012 -- Joye, along with Mel and his sister Maura, accompanied Hutton to Panama for stem cell treatment for his hip.

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, today announced treatment of the second patient in its Phase 1/2 clinical trial for Stargardts macular dystrophy (SMD) using retinal pigment epithelial (RPE) cells derived from human embryonic stem cells (hESCs). The surgery was performed on Friday, June 29 at Moorfields Eye Hospital in London, the same site as the first patient treatment in January, by a team of surgeons led by Professor James Bainbridge, consultant surgeon at Moorfields and Chair of Retinal Studies at University College London. The procedure was successfully performed without any complications. ACT and Moorfields Eye Hospital recently received clearance from the Data and Safety Monitoring Board (DSMB) to treat the final two patients in the first cohort of this clinical trial.

We are very pleased to continue our forward momentum with both our U.S. trials and our European trial, commented Gary Rabin, chairman and CEO. It was less than a month ago that we received DSMB approval to treat the second and third patients in our E.U. trial, and it is very gratifying to have already completed dosing of the second. It is a pleasure to be working with Professor Bainbridge and the rest of his team at Moorfields Eye Hospital, and we continue to be encouraged by the steady progress of the trial thus far.

The Phase 1/2 trial is designed to determine the safety and tolerability of hESC-derived RPE cells following sub-retinal transplantation in patients with SMD at 12 months, the studys primary endpoint. It will involve a total of 12 patients, with cohorts of three patients each in an ascending dosage format. It is similar in design to the U.S. trial for SMD that was initiated in July 2011.

The European Medicines Agency's (EMA) Committee for Orphan Medicinal Products (COMP) has officially designated ACT's human embryonic stem cell (hESC)-derived retinal pigment epithelial (RPE) cells as an orphan medicinal product for the treatment of Stargardt's Macular Dystrophy (SMD).

More information on the status of the companys clinical trials will be posted today on Mr. Rabins Chairmans blog.

About Stargardts Disease Stargardts disease or Stargardts Macular Dystrophy is a genetic disease that causes progressive vision loss, usually starting in children between 10 to 20 years of age. Eventually, blindness results from photoreceptor loss associated with degeneration in the pigmented layer of the retina, called the retinal pigment epithelium, which is the site of damage that the company believes the hESC-derived RPE may be able to target for repair after administration.
