They're called "no-option patients."

They've endured angioplasty, stent procedures, bypasses and a long line of medications. None of the treatments has fixed the plaque-plugged coronary arteries that trigger angina, starve the heart of blood and force people to hunch in pain after walking twoblocks.

Adult stem cell research at an Oxnard hospital is aimed at giving themchoices.

"A patient who has no hope will have some hope," said Dr. Nabil Dib, a world-renowned researcher partnering with St. John's Regional Medical Center. "It's a hope for potential therapy that will revise the way we treat cardiovasculardisease."

Stem cells are blank cells that function as the body's building blocks. They are able to grow into many different kinds of cells, including blood, muscle and tissue. Dib's work involves adult stem cells harvested from his patients, as opposed to stem cells that come from embryos and trigger ethicaldebates.

In a clinical trial starting at St. John's and 49 other hospitals across the country, the adult stem cells will be isolated and used to create new blood vessels. It's a way of manipulating the body into building new pathways for blood flow impeded by barricadedarteries.

"We're doing like a bypass a biological bypass," Dibsaid.

The trial is part of a genre of research aimed at using the body's own resources to repair the heart. It could reduce consequences ranging from heart transplants and hospitalizations to heart failure anddeath.

New stem cell research could bring choices to heart patients

Newswise LOS ANGELES (Oct. 2, 2012) Researchers at Cedars-Sinais Maxine Dunitz Neurosurgical Institute have found that a blood vessel-building gene boosts the ability of human bone marrow stem cells to sustain pancreatic recovery in a laboratory mouse model of insulin-dependent diabetes.

The findings, published in a PLoS ONE article of the Public Library of Science, offer new insights on mechanisms involved in regeneration of insulin-producing cells and provide new evidence that a diabetics own bone marrow one day may be a source of treatment.

Scientists began studying bone marrow-derived stem cells for pancreatic regeneration a decade ago. Recent studies involving several pancreas-related genes and delivery methods transplantation into the organ or injection into the blood have shown that bone marrow stem cell therapy could reverse or improve diabetes in some laboratory mice. But little has been known about how stem cells affect beta cells pancreas cells that produce insulin or how scientists could promote sustained beta cell renewal and insulin production.

When the Cedars-Sinai researchers modified bone marrow stem cells to express a certain gene (vascular endothelial growth factor, or VEGF), pancreatic recovery was sustained as mouse pancreases were able to generate new beta cells. The VEGF-modified stem cells promoted growth of needed blood vessels and supported activation of genes involved in insulin production. Bone marrow stem cells modified with a different gene, PDX1, which is important in the development and maintenance of beta cells, resulted in temporary but not sustained beta cell recovery.

Our study is the first to show that VEGF contributes to revascularization and recovery after pancreatic injury. It demonstrates the possible clinical benefits of using bone marrow-derived stem cells, modified to express that gene, for the treatment of insulin-dependent diabetes, said John S. Yu, MD, professor and vice chair of the Department of Neurosurgery at Cedars-Sinai, senior author of the journal article.

Diabetes was reversed in five of nine mice treated with the injection of VEGF-modified cells, and near-normal blood sugar levels were maintained through the remainder of the six-week study period. The other four mice survived and gained weight, suggesting treatment was beneficial even when it did not prompt complete reversal. Lab studies later confirmed that genetically-modified cells survived and grew in the pancreas and supported the repopulation of blood vessels and beta cells.

Anna Milanesi, MD, PhD, working in Yus lab as an endocrinology fellow, is the articles first author. The researchers cautioned that although this and other related studies help scientists gain a better understanding of the processes and pathways involved in pancreatic regeneration, more research is needed before human clinical trials can begin.

Insulin-dependent diabetes occurs when beta cells of the pancreas fail to produce insulin, a hormone that regulates sugar in the blood. Patients must take insulin injections or consider transplantation of a whole pancreas or parts of the pancreas that make insulin, but transplantation carries the risk of cell rejection.

Study Sheds Light on Bone Marrow Stem Cell Therapy for Pancreatic Recovery

IRVINE, CA--(Marketwire - Oct 1, 2012) - Oct. 3 marks International Stem Cell Awareness Day, a global celebration where leading scientists, researchers and supporters will acknowledge the scientific advances of stem cell research and its ability to potentially treat a variety of diseases and injuries in the 21st century. This dedicated community is committed to unlocking the potential of stem cells and has made significant strides since the discovery of a method to grow human stem cells less than 15 years ago.

"This is a critical and historic time for stem cell research," said Peter Donovan, Ph.D., director, Sue & Bill Gross Stem Cell Research Center, UC Irvine. "We're literally on the brink of developing new treatments for some of the world's most devastating diseases and injuries. The act of simply raising awareness about this research is one of the best things people can do to help accelerate the process. This event is a great opportunity for everyone to help spread the word and build momentum through a timely mass effort."

Scientists at UC Irvine and other research facilities around the globe continue to work diligently to develop therapies to treat life threatening and debilitating conditions such as Alzheimer's disease, multiple sclerosis, macular degeneration, cancer, Huntington's disease, Parkinson's disease, brain disorders and paralysis caused by spinal cord injuries. These efforts continue to give hope to millions who suffer from these devastating conditions by offering revolutionary treatments and potential cures.

There are several research programs taking place at the Sue & Bill Gross Stem Cell Research Center at UC Irvine that continue to break down barriers and open doors to new treatments for major diseases and injuries:

Spinal Cord and Traumatic Brain Injuries: Neurobiologist Hans Keirstead, Ph.D., as well as husband and wife scientists Aileen Anderson, Ph.D., and Brian Cummings, Ph.D., are conducting stem cell studies to develop treatments for the more than 1.3 million Americans who suffer from spinal cord injuries. Their advancements have led to the world's first clinical trial of human neural stem cell-based therapy for chronic spinal cord injuries (Anderson/Cummings) and the first FDA approved clinical trials using embryonic stem cells (Keirstead). Their research is significant because no drug or other forms of treatment have been able to restore function for those suffering from paralysis. In addition, Cummings and Anderson are applying their stem research to traumatic brain injury, a leading cause of death and disability worldwide, especially in children and young adults.

Alzheimer's Disease: An estimated 35 million people worldwide suffer from Alzheimer's disease, five million of whom live in the U.S. Frank LaFerla, Ph.D., director of UC Irvine's Institute for Memory Impairments and Neurological Disorders, and Matthew Blurton-Jones, Ph.D., of the Sue & Bill Gross Stem Cell Research Center, UC Irvine, have shown for the first time that neural stem cells can rescue memory in mice with advanced Alzheimer's disease, raising hope for a potential treatment in humans. Their work is expected to move to clinical trials in less than five years.

Huntington's Disease: Huntington's disease is a degenerative and ultimately fatal brain disorder that takes away a person's ability to walk, talk and reason. It affects about 30,000 people in the U.S. with another 200,000 or more likely to inherit the disorder. Leslie Thompson, Ph.D., and her team of researchers are currently investigating new stem cell lines and techniques to support the area of the brain that is susceptible to the disease with the hope of developing a cure for future generations.

Macular Degeneration, Retinitis Pigmentosa and Inherited Blindness: Henry Klassen, M.D., Ph.D. has focused his stem cell research on regenerating damaged retinal tissue to restore sight to people suffering from retinitis pigmentosa (an inherited form of degenerative eye disease) and macular degeneration which usually affects older people and leads to loss of vision. Macular degeneration affects millions of Americans. His work hopes to find cures and treatments for corneal and retinal eye disease.

New Website Helps Spread the Word Online To commemorate International Stem Cell Awareness Day and encourage support of stem cell research, an interactive website has been created. Advocates are asked to visit http://www.StemCellsOfferHope.com and share online a wide range of key facts, downloadable images and links to other valuable resources within their social networks.

International Stem Cell Awareness Day Events at UC Irvine The Sue & Bill Gross Stem Cell Research Center at UC Irvine will celebrate International Stem Cell Awareness Day by hosting three special events. An open house will take place on Oct. 1 for high school students. A UC Irvine student, faculty and staff open house will take place on Oct. 2. Finally, an all-day science symposium on Oct. 3 will feature a "Meet the Scientist" interactive forum. The forum and symposium are open to all UC Irvine scientists, clinicians, graduate students, post-docs and members of the community. To RSVP for any these events or for more information, include the name of the event in the subject line and email stemcell@research.uci.edu.

World Renowned Scientists and Advocates to Celebrate and Shine Light on Stem Cell Breakthroughs

For more than 40 years, Lesley Kelly of Glasgow, Scotland, lived with third-degree burns that stretched over 60 percent of her body.

Kelly was 2 years old when she fell into a bathtub filled with hot water that scorched most of the right side of her body. She lost full range of motion around many of her joints.

"When you have bad scarring, the buildup is very thick and has no elasticity," said Kelly, 45, whose right elbow was most affected by the buildup of scar tissue. "The problem with thermal burn scarring [is that] it's hard to get the range of motion."

Kelly underwent numerous reparative surgeries through the years, but the scar tissue continued to grow back. The procedures did not lessen the look of her scars.

In 2011, Kelly underwent a new, experimental procedure that used stem cells from her own fat tissue to repair the buildup around her right elbow.

Surgeons cleaned the scar buildup around the elbow and used liposuction to pull fat from off Kelly's waist. They separated the fat cells from the stem and regenerative cells, which were then injected into the wound on Kelly's arm. The procedure took less than two hours.

Within months, Kelly was able to regain 40 degrees of motion that she had lost more than 40 years ago.

"If this technology was available earlier in my life, my scars would not have been as bad," said Kelly.

There are an estimated 50,000 to 70,000 burn cases each year in the U.S., according to the American Burn Association.

The stem cell therapy, approved in the U.K. to treat soft tissue wounds, is now gaining traction in the U.S.
