Surgeons Urge Caution: Stem Cell Treatments Untested in Aesthetic Surgery

Doctors Haeck, Eaves, and Rohrich write joint ASAPS/ASPS statement calling for more research into stem cell facelift and stem cell breast augmentation.

Dallas, TX (PRWEB) February 22, 2012

There is little evidence to support the safety and effectiveness of procedures, equipment and treatments that have been advertised using adult stem cells for aesthetic reconstruction, including plastic surgery and facial rejuvenation, according to physicians writing in Plastic and Reconstructive Surgery.

Dr. Rod J. Rohrich, chairman of the Department of Plastic Surgery at UT Southwestern Medical Center and editor-in-chief of the journal, published a position statement on “stem cell facelifts” and “stem cell breast augmentation,” also known as “natural breast augmentation.” Dr. Felmont F. Eaves III of Chapel Hill, N.C., and Dr. Phillip C. Haeck of Seattle, Wash.,collaborated on the statement on behalf of the American Society for Aesthetic Plastic Surgery (ASAPS) and the American Society of Plastic Surgeons (ASPS).

“There are encouraging data from studies in laboratories to suggest that the use of adult stem cells is a very promising field and may produce beneficial medical therapies to treat a variety of diseases,” the doctors said in the statement. They emphasized that there is a lack of consistency in the way stem cell facelift procedures are performed, and pointed out that many procedures are being advertised by physicians who are not board-certified for this type of treatment, and devices being sold for aesthetic stem cell treatments have not been approved for human use in the U.S.

In the report, the doctors encourage their peers to continue reporting clinic results and experimental research to peer-reviewed plastic surgery journals to both promote good science and to foster safety and best practices for stem cell use in aesthetic procedures. “Much more research needs to be conducted before any definitive statements can be made,” the report said. “[Until then,] stem cell based procedures should be performed in compliance with FDA regulatory guidelines.”

Dr. Rohrich said many of the advertisements claiming stem cells can aid in restoring facial and body youthfulness come from outside the U.S. “Further direct, approved clinical research is needed to validate those claims,” he said, “but the future is potentially bright for the use of adult stem cells in both plastic surgery and facial rejuvenation, as well as in medical procedures, such as restoring nerve and brain damage resulting from trauma or cancer, as well as reversing the severe effects of auto immune disease.”

MediVet-America Partners With Butler Schein Animal Health to Distribute World's Leading Animal Stem Cell Technology to …

Global leader in animal stem cell technology is poised for significant expansion through new partnership with top U.S. companion animal health distribution company.

Las Vegas, Nevada (PRWEB) February 22, 2012

MediVet-America, the global leader in veterinary stem cell technology and regenerative medicine, has entered into a distribution partnership with Butler Schein Animal Health, a division of Henry Schein, the leading companion animal health distribution company in the U.S., to sell and distribute stem cell kits and equipment to veterinarians serving the nation’s fast-growing $50 billion pet industry.

The announcement was made today at the Western Veterinary Conference in Las Vegas by Jeremy Delk, CEO of MediVet-America.

The two companies will partner to sell and distribute MediVet-America’s advanced stem cell technology to more than 26,000 veterinary clinics nationwide. Adult animal stem cell technology uses the body’s own regenerative healing power to help treat dogs, cats, horses and other animals suffering from painful arthritis, hip dysplasia and tendon, ligament and cartilage injuries and other ailments.

The Adipose-Derived Stem Cell Procedure Kit and state of the art equipment, co-developed with Medical Australia, enable veterinarians to remove a small sample of fat, separate the stem cells, then activate and inject them into affected areas.

“We are pleased to be teaming up with Butler Schein, the largest companion animal health distribution company in the nation,” said Delk. “Their strong track record in sales and distribution will further fuel our rapid growth and bring this breakthrough technology to more leading veterinary practices across the country.”

To introduce the distribution partnership, Delk said MediVet-America has developed an exclusive program of product and service offers that will be made available only to Butler Schein customers.

Veterinary practitioners in more than 200 markets throughout 42 states now perform the drug-free procedure entirely in their own clinics more quickly, effectively and economically than earlier generation animal stem cell therapy. MediVet-America’s new treatment, developed in Australia, is available in 26 countries worldwide.

“This exciting partnership will allow even more of our colleagues unparalleled access to MediVet-America’s superior technology, providing the most affordable and efficacious stem cell therapy in the industry,” said Mike Hutchinson, D.V.M., the world’s leading animal stem cell practitioner. Dr. Hutchinson, who has spoken around the world about stem cell therapy, most recently in Tokyo, has performed more than 300 procedures over the last 18 months in his practice near Pittsburgh, PA.

Partnering with the leading animal health manufacturers in the world, Butler Schein maintains an order-fill ratio greater than 98 percent, and is positioned to bring the broadest selection of veterinary products and strategic business solutions to veterinarians, including:

    A comprehensive product offering for companion animal, equine and large animal practices including biologicals, diagnostics, nutritionals, parasiticides and pharmaceuticals

    Technology hardware and software solutions     Capital equipment, supply products and repair services     Practice design and remodeling, client marketing and financial solutions

Stem cells are basic biological cells with the ability to differentiate into specialized tissue cells and regenerate new cells to replace or repair damaged tissue. The stem cells used in veterinary medicine are not embryonic, which have attracted controversy over the years, but are taken from adipose (fat) tissue of the adult animal.

Americans spent an estimated $50.8 billion in 2011 on their companion animals, according to the American Pet Products Association, up from $28.5 billion in 2001. MediVet-America’s stem cell treatment costs about $1,800 for small animals, $2,400 for horses. Stem cells also can be frozen and banked for future use through MediVet Lab Services.

MEDIVET-AMERICA

A research and development company and global leader in veterinary stem cell technology, MediVet-America provides innovative cell applications for the therapeutic care of animals. Headquartered in Nicholasville, Kentucky, MediVet-America develops advanced cellular designed kits and services for the treatment of arthritis and degenerative joint disease.

Carrboro man to get stem cell transplant
Treatment a first at UNC

BY ELIZABETH SWARINGEN, Special to The Chapel Hill News

CHAPEL HILL - Three infusions of your own stem cells - each infusion over a 21-day hospitalization - can seem daunting. But, when it's your best chance for beating a recurrence of testicular cancer, you look forward to it."It doesn't seem intimidating to me at all," said David Alston, 42, of Carrboro. "You don't normally think of stem cell bone marrow transplants as treatment for testicular cancer, but it has been done in New York with success. I'm pleased it's available to me here at UNC Hospitals."This month Alston is having the first triple-tandem transplant done in an adult at UNC Hospitals.The process involves harvesting and freezing his own stem cells, receiving high-dose chemotherapy to attack the cancer, then having the stem cells infused over three back-to-back hospitalizations."He's young and otherwise healthy, and we think this is the right thing for him," said Dr. Paul M. Armistead, assistant professor of medicine in the Division of Hematology/Oncology, a member of the UNC Lineberger Comprehensive Cancer Center and leader of Alston's transplant team. "This is his best chance for being cured."Alston, a Charlotte native, was diagnosed with aggressive testicular cancer in March 2011 after experiencing an "avalanche of symptoms.""I didn't have a lump, but I had some weird back pain and loss of feeling in one leg," David said. "By the time I had some scans, we found lymph node involvement in a lot of places. Essentially, the cancer had gone on vacation all over my body."Testicular cancer is one of the more curable cancers, often cured in the first round of chemotherapy, said Dr. Kim Rathmell, associate professor of medicine, a member of UNC Lineberger Comprehensive Cancer Center and Alston's medical oncologist.Aggressive chemotherapy sent the cancer into remission, and by August Alston returned to his long-time job at Weaver Street Market in Chapel Hill's Southern Village.Routine blood test results in December surprised everyone: the cancer was back."Because of the way David's cancer came back, a more aggressive approach than chemotherapy alone was needed," said Rathmell, adding how hard it was knowing Alston faced treatment again. "I shop that store, and I had seen him back at work."Dr. Matthew Milowsky, who participated in the development of the triple-tandem transplant for testicular cancer at Memorial Sloan Kettering in New York City, joined UNC Lineberger Comprehensive Cancer Center last fall as co-director of UNC's urologic oncology program. Rathmell quickly recruited him to Alston's team."We have everything we need here at UNC to treat David," Rathmell said. "Had David come to us five years ago, when this recommended treatment was newer and we didn't have local expertise, I would likely have referred him elsewhere. Today, we are very comfortable doing this transplant here. And it's a total team approach."In January, Alston began receiving two types of chemotherapy to mobilize his stem cells in preparation for collection.This chemotherapy featured one less drug than what he endured after initial diagnosis and yielded fewer side effects."It was night and day difference," he said, remembering the physical and mental side effects that sent him into the ICU last spring. "By comparison, what I'm doing in preparation for the transplant has been rather effortless."But the process is complicated and has many moving parts."David will have five chemotherapy infusions administered by two separate medical teams that have to work together through a lot of logistics about what happens when," said Armistead. "That David is organized and intelligent and sends a lot of questions to Dr. Rathmell and me via email, he's helping himself stay on top of things. Having a patient who is fully aware of what's going on has kept us on our toes and helped us develop and coordinate a more fool-proof system."Still, as a single, stubbornly independent man, Alston needed help and support. Luckily, his mother, Barbara Alston, a retired medical professional from Concord, is by his side.Both are staying at SECU Family House, the 40-bedroom hospital hospitality house minutes from UNC Hospitals for seriously ill adult patients and their family member caregivers.The Alstons will stay at Family House during the nine weeks total that David is expected to be hospitalized. He will join her between transplants and for post-transplant monitoring."It's a comfort being here at Family House," Barbara Alston said. "If we need something, it's taken care of, both here and at the hospital. I'm assured David's getting the care he needs. I'm helping him whenever and wherever I can."SECU Family House will play an even larger role in Alston's recovery post-transplant, both Rathmell and Armistead agreed."This treatment is intense, and David will be more in the hospital than out," Rathmell said. "He will need a solid support system, and he has that with his mother. It's a fragile time, and she has his best interest at heart.""Post-transplant David will need to be monitored closely because his immune system will be very weak," Armistead said. "His mother's medical background is a bonus. The Family House folks are used to immune-suppressed patients and can get them to the hospital quickly if needed."Alston has kept himself swimming in information to minimize the fear and mystery. Barbara has been the great translator when his own efforts didn't yield the level of detail he needed."The constant learning gives it all a degree of routine that took some of the scariness away," Alston said. "But you can't be too independent or too brainy when you have cancer."Cancer blows you out of the water, but it leaves you with valuable insight," he said. "How you deal with cancer is self-guided and you learn things about yourself and your personality that you never knew. It's the ultimate in snatching the silver lining from a cloud."

Cancer Stem Cell Research Drives Growth in RBCC’s Target Market

NOKOMIS, Fla.--(BUSINESS WIRE)--

Research into Cancer Stem Cells (CSC) is on the rise, fueling industry growth that Rainbow Coral Corp. (OTCBB: RBCC.OB - News) expects to translate into demand for n3D cell growth technologies.

RBCC is finalizing an equity funding agreement with n3D Biosciences, the maker of a revolutionary new system that allows scientists to grow three-dimensional cell cultures more easily than ever before. The device, called the Bio-Assembler, could have an extraordinary impact on cell research worldwide, and RBCC expects to find a strong market for the device once its funding agreement with n3D is finalized.

Many cancers, including breast, prostate, pancreatic, colon, brain, and lung cancers, contain a subset of stem-like cells understood to play a critical role in the development and progression of the disease. Research suggests that these cells, called Cancer Stem Cells, are able to “seed” new tumor formation and drive metastasis.

Because these cells are believed to be at the root of the development and spread of cancer, they’re quickly becoming the center of cancer diagnostics and biomarkers. CSCs are resistant to a number of chemotherapy drugs and radiotherapy, and approximately 20 different strategies are currently being pursued in the hope of selectively targeting CSCs. This creates a huge opening for new companies and technologies dedicated to streamlining cellular research.

RBCC believes that the Bio-Assembler could allow researchers to dramatically shorten the development timeline for new CSC drugs and treatments, potentially proving very lucrative to the company.

Stem cell implants boost monkeys with Parkinson's

Monkeys suffering from Parkinson's disease show a marked improvement when human embryonic stem cells are implanted in their brains, in what a Japanese researcher said Wednesday was a world first.

A team of scientists transplanted the stem cells into four primates that were suffering from the debilitating disease.

The monkeys all had violent shaking in their limbs -- a classic symptom of Parkinson's disease -- and were unable to control their bodies, but began to show improvements in their motor control after about three months, Kyoto University associate professor Jun Takahashi told AFP.

About six months after the transplant, the creatures were able to walk around their cages, he said.

"Clear improvements were confirmed in their movement," he said.

Parkinson's disease is a progressive neurological illness linked to a decrease in dopamine production in the brain. There is currently no medical solution to this drop off in a key neurotransmitter.

The condition, which generally affects older people, gained wider public recognition when Hollywood actor Michael J. Fox revealed he was a sufferer.

Takahashi said at the time of the implant about 35 percent of the stem cells had already grown into dopamine neuron cells, with around 10 percent still alive after a year.

He said he wants to improve the effectiveness of the treatment by increasing the survival rate of dopamine neuron cells to 70 percent.

"The challenge before applying it to a clinical study is to raise the number of dopamine neuron cells and to prevent the development of tumours," he said.

"I would like to make this operation more effective and safe" before clinical trials, Takahashi said.

Takahashi said so far he had used embryonic stem cells, which are harvested from foetuses, but would likely switch to so-called Induced Pluripotent Stem (iPS) cells, which are created from human skin, for the clinical trial.

His team, which has also transplanted iPS cells into monkeys, are now looking to see if the primates with Parkinson's disease show similar improvements in their motor control.

Scientists say the use of human embryonic stem cells as a treatment for cancer and other diseases holds great promise, but the process has drawn fire from religious conservatives, among others.

Opponents say harvesting the cells, which have the potential to become any cell in the human body, is unethical because it involves the destruction of an embryo.

The Japanese government currently has no guidelines on the use of human stem cells in clinical research.

In October last year, the Court of Justice of the European Union banned the patenting of stem cells when their extraction causes the destruction of a human embryo, a ruling that could have repercussions on medical research.

Scientists warned that the ruling would damage stem cell research in Europe, while the Catholic church hailed it as a victory for the protection of human life.

Editor’s move sparks backlash

Bioethicist Glenn McGee’s new job raised questions of conflict of interest at the journal he founded.

J. WILSON/KRT/NEWSCOM

The field of bioethics is embroiled in a period of soul-searching, sparked by a startling career move by one of its biggest names.

Glenn McGee is the editor-in-chief of the American Journal of Bioethics (AJOB), the most cited bioethics journal, which he founded in 1999. Since December 2011, he has also been president for ethics and strategic initiatives at CellTex Therapeutics in Houston, Texas, a controversial company involved in providing customers with unproven stem-cell therapies. A CellTex press release says that “Dr McGee’s responsibilities will include ensuring that all of the firm’s work, centered on adult stem cells, will meet the highest ethical standards of the medical and scientific communities.”

Although McGee has said he will leave the journal on 1 March, many bioethicists have criticized him, the journal’s editorial board and its publisher, London-based Taylor and Francis. They argue that in holding both posts, McGee has a conflict of interest between his responsibilities to the journal and his new employer’s desire to promote the clinical application of stem-cell treatments that are not approved by the US Food and Drug Administration.

“Imagine if the Editor of the New England Journal of Medicine took a job as Vice President at Merck, and the Mass Medical Society asked him to stay on as Editor, opining that the conflicts of interest would be manageable. One might rightly wonder, ‘What are these people smoking?’,” says John Lantos, director of the Children’s Mercy Bioethics Center in Kansas City, Missouri, and a past president of the American Society for Bioethics and Humanities.

More broadly, bioethicists are questioning whether it can ever be acceptable to work for companies, which, they argue, may be using the appointment to present a veneer of ethical probity. The episode brings to a head concerns that have emerged among bioethicists over the past decade, says Insoo Hyun, a stem-cell bioethicist at Case Western Reserve University in Cleveland, Ohio. “It’s a perfect storm,” he says.

McGee is a leading voice on one side of the debate, arguing that bioethics must have practical relevance. For the past three years he has been chair of bioethics at the non-profit Center for Practical Bioethics in Kansas City, where he ran a course for those who might go on to chair hospital ethics committees or serve as ethical advisers to corporations.

But during McGee’s tenure as editor-in-chief of the AJOB, four editors are known to have resigned from the editorial board because of differences in opinion over how the journal handles conflicts of interest. Two left this month, including Lantos, who wrote on his blog that he will no longer work with the journal because of McGee’s simultaneous employment at the AJOB and CellTex, and frustration over the lack of a clear conflict-of-interest policy at the AJOB. In response to Nature’s questions about the situation, Taylor and Francis responded that it “is grateful for Dr McGee’s editorship of AJOB” and “supportive of Glenn’s decision to step down”.

On 17 February, McGee announced that he is merely acting in an advisory capacity at the journal until 1 March, when its new editors-in-chief take over. They are David Magnus, director of the Center for Biomedical Ethics at Stanford University, California, and Summer Johnson McGee, director of graduate studies at the Center for Practical Bioethics and the journal’s current executive editor. She is also Glenn McGee’s wife.

“Mainstream bioethics is no longer speaking truth to power.”

Responding to questions from Nature, Summer Johnson McGee says that the journal has a conflict-of-interest policy that requires editors to withdraw from reviewing a manuscript if they perceive a conflict. She calls allegations that her appointment results from her relationship with her husband “baseless and sexist”. “David Magnus and I were hired by our publisher, not by my husband.” Magnus says that at least a dozen editorial board members have supported his and Summer Johnson McGee’s appointments. Two even indicated that Glenn McGee should have been able to retain an advisory or editorial role.

Other bioethicists’ blogs and Twitter feeds about the episode have expressed concerns, however. Leigh Turner of the University of Minnesota, Minneapolis, called on the entire editorial board of the AJOB to resign for allowing the situation to persist. And many say that McGee’s move illustrates a broader problem. “Mainstream bioethics is no longer speaking truth to power,” complains Jan Helge Solbakk at the University of Oslo. “Instead it has become the handmaiden of the medico-industrial complex, and of bioscience and technology.”

So how should companies get their advice on bioethics? Magnus never takes cash from industry for advising or speaking — “I’m a hardass about that” — but he believes that bioethicists can work for industry as long as they give up their academic positions, including posts on journal editorial boards.

Working for a respected company may be acceptable to some bioethicists, but McGee’s new employer comes with a great deal of baggage. CellTex, which was founded last year and as yet has no website, licenses stem-cell technology from Seoul-based RNL Bio. The South Korean company has made a business out of taking fat cells from people, processing them in a way that they say increases the number of mesenchymal stem cells, and then reinjecting them in an effort to treat conditions such as spinal cord injury.

McGee already had a connection with RNL Bio. In 2010, two patients died following injections of RNL’s cells. McGee, working for stem-cell lobby group the International Cellular Medicine Society, based in Salem, Oregon, helped to conduct an investigation into the company. This concluded that only one of the two cases was likely to be related to the injections, and because the patient understood the risk the company was not culpable.

Jin Han Hong, the then president of RNL’s US subsidiary, admitted in 2010 that there was no clinical-trial evidence proving that these treatments are effective (Nature 468, 485; 2010). As treatment with RNL’s stem cells is not approved in the United States or South Korea, for the procedures the company sends patients to China or Japan, where regulations are less strictly enforced. Using RNL’s methods, CellTex is banking stem cells that have gone on to be used in a number of patients, including Rick Perry, governor of Texas (Nature 477, 377–378; 2011). CellTex says that it does not conduct medical procedures itself.

When Nature contacted McGee to put the criticisms to him, he directed us to previous statements indicating that he wants to put CellTex on firmer ethical ground by having it conduct clinical trials that meet standards set by the International Society for Stem Cell Research, based in Deerfield, Illinois, which represents most mainstream stem-cell researchers around the world.

Hyun warns that working directly for business can be fraught with danger, however good a bioethicist’s intentions. In 2005, he helped to craft the informed consent procedure for egg donations used in a cloning procedure by disgraced Korean stem-cell scientist Woo Suk Hwang. Following Hwang’s claim, later proved fraudulent, that he had cloned human embryos and harvested stem cells from them, it emerged that he had ignored the consent procedure for egg donations (Nature 438, 536–537; 2005), leading to embarrassment for Hyun.

“I know first hand how difficult it is to separate conflict of interest — to maintain the role of bioethicist,” says Hyun. “I know you need to not be too chummy with enterprises trying to speed ahead in stem cells.”

Energy network within cells may be new target for cancer therapy

Within each cell, mitochondria are constantly splitting in two, a process called fission, and merging back into one, called fusion. Before a cell can divide, the mitochondria must increase their numbers through fission and separate into two piles, one for each cell.

By reversing an imbalance of the signals that regulate fusion and fission in rapidly dividing cancer cells, researchers were able to dramatically reduce cell division, thus preventing the rapid cell proliferation that is a hallmark of cancer growth. Increasing production of the signal that promotes mitochondrial fusion caused tumors to shrink to one-third of their original size. Treatment with a molecule that inhibits fission reduced tumor size by more than half.

"We found that human lung cancer cell lines have an imbalance of signals that tilts them towards mitochondrial fission," said Stephen L. Archer, MD, the Harold Hines Jr. Professor of Medicine at the University of Chicago Medicine and senior author of the study. "By boosting the fusion signal or blocking the fission signal we were able to tip the balance the other way, reducing cancer cell growth and increasing cell death. We believe this provides a promising new approach to cancer treatment."

"This could be a potential new Achilles' heel for cancer cells," said the study's lead author, Jalees Rehman, MD, an associate professor of medicine and pharmacology at the University of Illinois at Chicago. "Many anticancer drugs target cell division. Our work shifts the focus to a distinct but necessary step: mitochondrial division. The cell division cycle comes to a halt if the mitochondria are prevented from dividing. This new therapy may be especially useful in cancers which become resistant to conventional chemotherapy that directly targets the cycle."

The researchers found that the mitochondrial networks within several different lung cancer cell lines were highly fragmented, compared to normal lung cells. Cancer cells had low levels of mitofusin-2 (Mfn-2), a protein that promotes fusion by tethering adjacent mitochondria, and high levels of dynamin-related protein (Drp-1), which initiates fission by encircling the organelle and squeezing it into two discrete fragments. The Drp-1 in cancer cells also tended to be in its most active form.

The researchers tested several ways to enhance fusion and restore the mitochondrial network, both in cell culture and in animal models. They used gene therapy to increase the expression of Mfn-2, injected a small molecule (mdivi-1) that inhibits Drp-1, and used genetic techniques to block the production of Drp-1. All three interventions markedly reduced mitochondrial fragmentation, increased networking and reduced cancer cell growth.

Although the authors identify mitochondrial fission and Drp-1 activation as a potential therapeutic target in lung cancer, "this is not a cure," Archer emphasized. The treatment drastically reduced tumor size but the tumors did not completely disappear. They continued to use high levels of glucose as fuel, a hallmark of cancer metabolism that can be seen on PET scans. "This remnant could be either a central cluster of cancer stem cells," Archer said, "or an inflammatory response, the immune system infiltrating the tumor."

"Inhibiting mitochondrial fission", Archer said, "did not show any significant toxicity in mice or rats, so we are quite optimistic that our findings can lead to the development of novel, clinically feasible therapies."

The substances used to block fusion are commercially available for research purposes, but they have not been tested in humans. Mdivi-1 has been used in animals to prevent kidney injury.

Although the focus on mitochondria is fairly new to cancer biologists—despite a flurry of interest in the 1920s stimulated by the German Nobel Prize laureate Otto Warburg—this organelle has long been a central focus for physicians and scientists interested in muscle biology, especially cardiac muscle.

Archer, a cardiologist, specializes in pulmonary hypertension. In this disorder, as in cancer, excessive cellular growth causes disease. The death of his cousin and close friend from lung cancer made him start thinking about the connections. Rehman is a German scientist and became interested in studying mitochondria after reading some of the historical Warburg papers in German.

The fact that two cardiologists, Archer and Rehman, decided to study cancer and collaborated with a team of basic scientists, a cancer physician and a pathologist is "an indicator of how interconnected modern biomedical research has become," Rehman said.

About VistaGen Therapeutics

VistaGen is a biotechnology company applying human pluripotent stem cell technology for drug rescue and cell therapy. VistaGen's drug rescue activities combine its human pluripotent stem cell technology platform, Human Clinical Trials in a Test Tube™, with modern medicinal chemistry to generate new chemical variants of once-promising small-molecule drug candidates. These are once-promising drug candidates discontinued by pharmaceutical companies during development due to heart toxicity, despite positive efficacy data demonstrating their potential therapeutic and commercial benefits. VistaGen uses its pluripotent stem cell technology to generate early indications, or predictions, of how humans will ultimately respond to new drug candidates before they are ever tested in humans.

Additionally, VistaGen's small molecule drug candidate, AV-101, is in Phase 1b development for treatment of neuropathic pain. Neuropathic pain, a serious and chronic condition causing pain after an injury or disease of the peripheral or central nervous system, affects approximately 1.8 million people in the U.S. alone. VistaGen plans to initiate Phase 2 clinical development of AV-101 in the fourth quarter of 2012. VistaGen is also exploring opportunities to leverage its current Phase 1 clinical program to enable additional Phase 2 clinical studies of AV-101 for epilepsy, Parkinson's disease and depression. To date, VistaGen has been awarded over $8.5 million from the NIH for development of AV-101.

Man 'stole dying son's care cash'

21 February 2012 Last updated at 16:32 ET

A businessman is accused of stealing £16,500 from a trust fund set up to pay for his son to have stem cell treatment in China for motor neurone disease.

Cardiff Crown Court heard people raised £55,000 in sponsored runs after Julian Emms, 46, of Caerwent, Monmouthshire, established a charity for son Michael.

A blank cheque he obtained to take him on a £3,000 trip to New York was cashed for the larger amount, the jury heard.

Mr Emms denies fraud. The trial continues.

The jury was told on Tuesday that Michael Emms was diagnosed with motor neurone disease, a degenerative neurological condition, while in his teens.

Emms went to their home and burned the cheques in front of them in a way which was deliberately theatrical”

End Quote Meirion Davies Prosecuting

The fundraising allowed him to go abroad for stem cell treatment but this failed.

After this, the jury was told, Mr Emms told his family he wanted £3,000 to fulfil Michael's dream of visiting New York.

He approached Michael's grandmother, Anne Brandon, one of the four people authorised to sign the charity's cheques, the court heard.

Meirion Davies, prosecuting, said: "Emms said he was booking a holiday to the USA for Michael and needed two cheques.

"One was for £3,000 for the holiday and the other was £300 for insurance.

"Mrs Brandon wrote the cheques out to a travel agency called Travelcare and signed them - but left them blank because Emms didn't know the exact amounts."

But Mrs Brandon and her husband David changed their minds and asked Mr Emms to return the cheques, Mr Davies said.

He said: "Emms went to their home and burned the cheques in front of them in a way which was deliberately theatrical.

"But one of them was in fact a blank piece of paper."

The court was told the defendant already cashed the other cheque for £16,500 after changing the payee to "cash".

Mr Emms was buying a £30,000 bio diesel processor at the time the cheque was cashed, the court was told.

The trial continues. Mr Emms denies fraud.

Michael Emms died in 2011, aged in his mid 20s.
