UCI stem cell researcher to receive $4.8 million in state funding

By Stem Cell Medical Center

CIRM grant will advance work on multiple sclerosis treatment

Irvine, Calif., May 24, 2012

A UC Irvine immunologist will receive $4.8 million to create a new line of neural stem cells that can be used to treat multiple sclerosis.

The California Institute for Regenerative Medicine awarded the grant Thursday, May 24, to Thomas Lane of the Sue & Bill Gross Stem Cell Research Center at UCI to support early-stage translational research.

CIRMs governing board gave 21 such grants worth $69 million to 11 institutions statewide. The funded projects are considered critical to the institutes mission of translating basic stem cell discoveries into clinical cures. They are expected to either result in candidate drugs or cell therapies or make significant strides toward such treatments, which can then be developed for submission to the Food & Drug Administration for clinical trial.

Lanes grant brings total CIRM funding for UCI to $76.65 million.

I am delighted that CIRM has chosen to support our efforts to advance a novel stem cell-based therapy for multiple sclerosis, said Peter Donovan, director of the Sue & Bill Gross Stem Cell Research Center.

MS is a disease of the central nervous system caused by inflammation and loss of myelin, a fatty tissue that insulates and protects nerve cells. Current treatments are often unable to stop the progression of neurologic disability most likely due to irreversible nerve destruction resulting from myelin deficiencies. The limited ability of the body to repair damaged nerve tissue highlights a critically important and unmet need for MS patients.

In addressing this issue, Lane who also directs UCIs Multiple Sclerosis Research Center will target a stem cell treatment that will not only halt ongoing myelin loss but also encourage the growth of new myelin that can mend damaged nerves.

Our preliminary data are very promising and suggest that this goal is possible, said Lane, a Chancellors Fellow and professor of molecular biology & biochemistry. Research efforts will concentrate on refining techniques for production and rigorous quality control of transplantable cells generated from high-quality human pluripotent stem cell lines, leading to the development of the most therapeutically beneficial cell type for eventual use in patients with MS.

Stem cells take root in drug development

By Uncategorized

Stem cells have assumed near-mythical status in the popular imagination as a possible cure for every disease under the sun. But while public attention has focused on their potential in regenerative medicine, stem cells have quietly gained a foothold in drug development a move that may hail a huge but unheralded shake-up of the biological sciences.

I think there are tremendous parallels to the early days of recombinant DNA in this field, says James Thomson, director of regenerative biology at the Morgridge Institute for Research in Madison, Wisconsin, and one of the founders of Cellular Dynamics International, also in Madison. I dont think people appreciated what a broad-ranging tool recombinant DNA was in the middle '70s." At the same time, he says, they underestimated the difficulty of using it in treatments.

Now stem cells are in a similar situation, he says, and although therapeutic use is likely to come to fruition eventually, people underappreciate how broadly enabling a research tool it is, he says.

Laboratory-grown stem cells hold much promise for regenerative medicine, but are being increasingly used in drug testing.

Drug companies began dipping a tentative toe into the stem-cell waters about two years ago (see 'Testing time for stem cells'). Now, the pharmaceutical industry is increasingly adopting stem cells for testing the toxicity of drugs and identifying potential new therapies, say those in the field.

Cellular Dynamics sells human heart cells called cardiomyocytes, which are derived from induced pluripotent stem (iPS) cells. Thomson says that essentially all the major pharma companies have bought some. The company also produces brain cells and cells that line blood vessels, and is about to release a line of human liver cells.

Yet Cellular Dynamics is just one of the companies in the field. Three years ago, stem-cell biologist Stephen Minger left his job in UK academia to head GE Healthcares push into stem cells (see 'Top scientist's industry move heralds stem-cell shift'). The medical-technology company, headquartered in Chalfont St. Giles, UK, has been selling human heart cells made from embryonic stem (ES) cells for well over a year, and is due to start selling liver cells soon.

Minger and his team at GE Healthcare assessed the heart cells in a blind trial against a set of unnamed drug compounds to see if the cells would reveal which compounds were toxic. When the compounds were unmasked, Minger says, they found that the cells had been affected by the known toxic compounds. But, crucially, in a number of cases, the cells identified a problem that had only been discovered after the drugs had reached the market and after they had been approved by agencies such as the US Food and Drug Administration (FDA).

These are compounds which went all the way through animal testing, then went through phase I, II, III and then were licensed in many cases by the FDA, says Minger.

Biostem U.S., Corporation Announces $5,000,000 Financing Agreement Through Private Placement of Stock

By Uncategorized

CLEARWATER, FL--(Marketwire -05/24/12)- Biostem U.S., Corporation, (HAIR.PK) (HAIR.PK) (Biostem, the Company), a fully reporting public company in the stem cell regenerative medicine sciences sector, announces a $5,000,000 financing agreement through private placement of stock.

CEO, Dwight Brunoehler, announced today that the company has signed an agreement with a funder to issue 20,000,000 shares of the company's common stock in exchange for $5,000,000 in cash or 25 cents ($.25) per share. No other considerations will be granted to the funder in exchange for the cash payment.

In announcing the funding agreement, Mr. Brunoehler commented, "We consider the eagerness of the funder to acquire Biostem shares at a price above the current market to be a tribute to our proven proprietary technology to enhance hair re-growth using human stem cells. Although we anticipated funding the company through the sale of a convertible debenture, the funder insisted on being able to acquire stock at a set price now, rather than risk having to convert at higher prices later. Although Rule 144 sale restrictions usually cause private placements of stock to be executed at a discount to the market, Biostem feels that its current share price is not truly reflective of the value of its proprietary technology; as well as the fact that the technology is already being employed, and the overall size of the hair replacement marketplace. It was for this reason that the company and the funder were able to come to an agreement to price the private placement above the current share price."

Di'Anno Wants Former Iron Maiden Bandmate To Undergo Stem Cell Therapy

By Uncategorized

05/24/2012 . (Classic Rock) Former Iron Maiden singer Paul Di'Anno wants his ex-bandmate Clive Burr to undergo stem cell therapy, despite the costs and risks associated with the procedure.

Burr, the drummer with Maiden from 1979 until 1982, has been in a wheelchair as a result of multiple sclerosis, which has been attacking his nervous system since before he was diagnosed in 2002.

MS reduces the ability of the brain and spinal cord to communicate with each other, resulting in a wide range of potentially severe symptoms. The cause is unknown and there is no cure; but in 2009 researchers made the first breakthrough in reversing symptoms through stem cell therapy.

Di'Anno tells Talking Metal Pirate Radio Burr's condition is "not very good at all." He had a lot to say, read it here.

Stem-cell-growing surface enables bone repair

By Stem Cell Treatment

ScienceDaily (May 23, 2012) University of Michigan researchers have proven that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer. To prove the cells' regenerative powers, bone cells grown on this surface were then transplanted into holes in the skulls of mice, producing four times as much new bone growth as in the mice without the extra bone cells.

An embryo's cells really can be anything they want to be when they grow up: organs, nerves, skin, bone, any type of human cell. Adult-derived "induced" stem cells can do this and better. Because the source cells can come from the patient, they are perfectly compatible for medical treatments.

In order to make them, Paul Krebsbach, a professor of biological and materials sciences in the School of Dentistry, said, "We turn back the clock, in a way. We're taking a specialized adult cell and genetically reprogramming it, so it behaves like a more primitive cell."

Specifically, they turn human skin cells into stem cells. Less than five years after the discovery of this method, researchers still don't know precisely how it works, but the process involves adding proteins that can turn genes on and off to the adult cells.

Before stem cells can be used to make repairs in the body, they must be grown and directed into becoming the desired cell type. Researchers typically use surfaces of animal cells and proteins for stem cell habitats, but these gels are expensive to make, and batches vary depending on the individual animal.

"You don't really know what's in there," said Joerg Lahann, an associate professor of chemical engineering and biomedical engineering. For example, he said that human cells are often grown over mouse cells, but they can go a little native, beginning to produce some mouse proteins that may invite an attack by a patient's immune system.

The polymer gel created by Lahann and his colleagues in 2010 avoids these problems because researchers are able to control all of the gel's ingredients and how they combine. "It's basically the ease of a plastic dish," said Lahann. "There is no biological contamination that could potentially influence your human stem cells."

Lahann and colleagues had shown that these surfaces could grow embryonic stem cells. Now, Lahann has teamed up with Krebsbach's team to show that the polymer surface can also support the growth of the more medically-promising induced stem cells, keeping them in their high-potential state. To prove that the cells could transform into different types, the team turned them into fat, cartilage, and bone cells.

They then tested whether these cells could help the body to make repairs. Specifically, they attempted to repair 5-millimeter holes in the skulls of mice. The weak immune systems of the mice didn't attack the human bone cells, allowing the cells to help fill in the hole.

After eight weeks, the mice that had received the bone cells had 4.2 times as much new bone, as well as the beginnings of marrow cavities. The team could prove that the extra bone growth came from the added cells because it was human bone.

Stem cell treatment for heart failure takes small step forward

By Stem Cell Treatment

Researchers at the Technion-Israel Institute of Technology in Haifa, Israel, reported Tuesday that they had removed skin cells from two patents with heart failure, returned those cells to an embryonic state, and then transformed them into beating heart cells that could communicate with the patients existing heart tissue.

We have shown that it is possible to take skin cells from an elderly patient with advanced heart failure and end up with his own beating cells in a laboratory dish that are healthy and young the equivalent to this stage of his heart cells when he was just born, study leader Dr. Lior Gepstein said in a statement.

The discovery marks a small step toward a long-sought goal: using stem cells to regrow the cardiac tissue that is damaged in heart attacks. (The Times reported on the quest in February, 2011.) But it doesnt mean that patients with heart failure are likely to get shiny new hearts through stem cell treatments anytime soon.

Several hurdles stand in the way of using induced pluripotent stem cells, as the skin-derived cells are called, to reverse heart attack damage. The Israeli researchers acknowledged several. Such cells are known to spin out of control and cause cancer. Stem cell-derived cardiac cells have also had problems coordinating with normal heart rhythms. The team will need to be able to generate larger numbers of the cells before it can test the treatment, and will need to perfect transplant methods.

And if all those hurdles are crossed, scientists still wont know if the technology will work in people. What we produce in an animal model or in a petri dish is hardly what happens in a human. This is a first step. It will take five, 10, 15, maybe 20 years to reach fruition at the soonest, said Dr. Shephal Doshi, director of electrophysiology and pacing at Saint Johns Health Center in Santa Monica.

Most patients will have to wait to take advantage of other types of stem cell cures for heart failure as well including treatments that use cells derived from bone marrow to stimulate heart regeneration, treatments that use cardiac stem cells removed from the heart to build heart tissue and insert it back into the diseased organ and treatments that attempt to stimulate cardiac stem cells in place in the heart into action to rebuild tissues. These technologies are in varying stages of testing and development.

The Centers for Disease Control and Prevention has more information about heart failure in the U.S.

Growth Factor in Stem Cells May Spur Recovery From MS

By Stem Cell Clinic

Newswise A substance in human mesenchymal stem cells that promotes growth appears to spur restoration of nerves and their function in rodent models of multiple sclerosis (MS), researchers at Case Western Reserve University School of Medicine have found.

Their study is embargoed until published in the online version of Nature Neuroscience at 1 p.m. U.S. Eastern Standard Time on Sunday, May 20.

In animals injected with hepatocyte growth factor, inflammation declined and neural cells grew. Perhaps most important, the myelin sheath, which protects nerves and their ability to gather and send information, regrew, covering lesions caused by the disease.

The importance of this work is we think weve identified the driver of the recovery, said Robert H. Miller, professor of neurosciences at the School of Medicine and vice president for research at Case Western Reserve University.

Miller, neurosciences instructor Lianhua Bai and biology professor Arnold I. Caplan, designed the study. They worked with Project Manager Anne DeChant, and research assistants Jordan Hecker, Janet Kranso and Anita Zaremba, from the School of Medicine; and Donald P. Lennon, a research assistant from the universitys Skeletal Research Center.

In MS, the immune system attacks myelin, risking injury to exposed nerves intricate wiring. When damaged, nerve signals can be interrupted, causing loss of balance and coordination, cognitive ability and other functions. Over time, intermittent losses may become permanent.

Miller and Caplan reported in 2009 that when they injected human mesenchymal stem cells into rodent models of MS, the animals recovered from the damage wrought by the disease. Based on their work, a clinical trial is underway in which MS patients are injected with their own stem cells.

In this study, the researchers first wanted to test whether the presence of stem cells or something cells produce promotes recovery. They injected mice with the medium in which mesenchymal stem cells, culled from bone marrow, grew.

All 11 animals, which have a version of MS, showed a rapid reduction in functional deficits.

Analysis showed that the disease remained on course unless the molecules injected were of a certain size; that is, the molecular weight ranged between 50 and 100 kiloDaltons. Research by others and results of their own work indicated hepatocyte growth factor, which is secreted by mesenchymal stem cells, was a likely instigator.

Bentsen Stroke Center Awards Grants for Regenerative Medicine Research

By Uncategorized

Newswise Every year, approximately 795,000 people in the United States suffer a stroke and the late U.S. Senator and Democratic Party vice presidential candidate Lloyd Bentsen was one of them. As the senator and his wife, B. A., dealt with the challenges of stroke, they developed the idea for a stroke research center.

The couples efforts led to the 2009 opening of the Senator Lloyd and B.A. Bentsen Center for Stroke Research at The Brown Foundation Institute of Molecular Medicine for the Prevention of Human Diseases (IMM), a part of The University of Texas Health Science Center at Houston (UTHealth). Sen. Bentsen died prior to the centers opening.

In April at the IMM, B.A. Bentsen and one of the couples sons, Lan, got updates on six projects funded by the stroke center. The center was launched with a generous gift from the Bentsen family and the center distributes up to $1 million annually for research.

The primary focus of the Bentsen Stroke Center is to develop cell-based therapeutics, including the use of certain populations of stem cells, to reduce secondary brain injury and enhance recovery, said Brian R. Davis, Ph.D., interim director of Center for Stem Cell and Regenerative Medicine at the IMM, which is the academic and administrative home of the Bentsen Stroke Center. Davis is the Annie and Bob Graham Distinguished Chair in Stem Cell Biology at UTHealth.

In 2011 and 2012, Bentsen Stroke Center grants were awarded to UTHealth Medical School faculty members Jaroslaw Aronowski, Ph.D., Qi Lin Cao, Ph.D., Charles Cox Jr., M.D., Pramod Dash, Ph.D., Ying Liu, M.D., Ph.D., Sean Savitz, M.D. and Jiaqian Wu, Ph.D. They are the principal investigators for the studies.

Lessen injury progression

When a blood vessel in the brain ruptures, pooling blood accumulates in brain matter and can cause additional if not more serious problems. Aronowski, professor of neurology and director of cerebrovascular (stroke) research, is exploring a natural way to speed up blood cleanup to prevent further brain injury.

This cleanup is normally done by specialized cells called phagocytes. Unfortunately, this process takes weeks, thus allowing blood, which is now outside of the vessel to continue to damage the brain. Aronowski proposes to speed up the process by modifying the phagocytes. We identified components of machinery phagocytes used to scavenge and clean up blood debris. Now, we will isolate them from blood, modify their function and reinject them back to see if they do a better cleanup job, Aronowski said. He plans to conduct a preclinical trial.

Replace damaged nerve cells

When a person suffers a stroke, nerve cells or neurons can begin to die. Regenerative medicine researchers would like to create replacement cells. Cao, associate professor at The Vivian L. Smith Department of Neurosurgery, is conducting a preclinical study to select the best neural cell types to treat stroke.
