A Monsignor and Officer for Studies at the Pontifical Academy for Life called the cancellation a "sad event." Attendees are set to receive an official explanation

By Ewen Callaway of Nature magazine

The Vatican has abruptly cancelled a controversial stem-cell conference that was set to be attended by the Pope next month.

The Third International Congress on Responsible Stem Cell Research, scheduled for 25-28 April, was to focus on clinical applications of adult and reprogrammed stem cells. But a number of the invited speakers, including Alan Trounson, president of the California Institute for Regenerative Medicine in San Francisco, and keynote speaker George Daley, a stem-cell scientist at Children's Hospital Boston in Massachusetts, are involved in research using human embryonic stem cells, which the Catholic Church considers unethical. The previous two congresses had also included scientists who worked on such cells, without generating much controversy.

Father Scott Borgman, secretary of the Church's Pontifical Academy for Life, one of the conference organizers, says that logistical, organizational and financial factors forced the cancellation, which was announced on 23 March. The academy weighs in on bioethical and theological issues that are relevant to Church teachings.

The Catholic News Agency, an independent news service based in Englewood, Colorado, quoted an unnamed academy member who called the cancellation an "enormous relief to many members of the Pontifical Academy for Life, who felt that the presence on its program of so many speakers, including the keynote speaker, committed to embryonic stem cell research, was a betrayal of the mission of the Academy and a public scandal".

"I think the only interpretation is that we are being censored. It is very disappointing that they are unwilling to hear the truth," says Trounson. He had hoped to provide a "balanced perspective" on the potential clinical applications of stem cells, both adult and embryonic.

Meanwhile, some European scientists, who had called for a boycott because they believed the conference unfairly maligned embryonic stem cell research, cheered its cancellation.

Midlands Vet Uses Stem Cell Therapy for Pets in Pain

By Uncategorized

Columbia, SC (WLTX) --What if your pet couldn't walk anymore? One Midlands vet is using stem cell therapy to help.

For Beth Phibbs it's almost like a turning back of the hands of time.

"I call her my little miracle dog, because she's doing things she used to do," said Phibbs. "Now she's not on any medication, and she can go up and down the steps and she runs and jumps and things that she used to do when she was five."

Phibbs has spent the last 13 years loving and looking after her pet dog Maggie, and when she pet began to develop arthritis and a limp she had to take action. But when the first treatments stopped working, Phibbs and Maggie had to look to another options, dog stem cell therapy.

"I had no idea that animals were able to have they type of procedures," she said.

Dr. Kenneth Banks a veterinarian with the Bank Animal Hospital, performed the surgery for Maggie using her own stem cells in the one day procedure.

Banks said the stem cell therapy not only cost less than some other options, but was less invasive and had a quicker recovery time as well.

Still with about three similar procedures under his belt, even he didn't expect to see a such change in maggie just 40 days after the surgery.

"I wasn't sure we were gonna get the results this fast, we were expecting results, maybe not a good as she's done. We're real happy with her results," said Banks.

Now, after three years on medication and walking with a limp, Maggie's getting used to a new way of life -- one with out pain in her golden years.

Stem cell therapy possibly helpful in heart failure patients

CHICAGO -- A new study found that using a patient's own bone marrow cells may help repair damaged areas of the heart caused by heart failure, according to research presented today at the American College of Cardiology's 61st Annual Scientific Session. The Scientific Session, the premier cardiovascular medical meeting, brings cardiovascular professionals together to further advances in the field.

Millions of Americans suffer from heart failure, the weakening of the heart muscle and its inability to pump blood effectively throughout the body. If medications, surgery, or stents fail to control the disease, doctors often have few treatment options to offer.

This is the largest study to date to look at stem cell therapy, using a patient's own stem cells, to repair damaged areas of the heart in patients with chronic ischemic heart disease and left ventricular dysfunction. Researchers found that left ventricular ejection fraction (the percentage of blood leaving the heart's main pumping chamber) increased by a small but significant amount (2.7 percent) in patients who received stem cell therapy. The study also revealed that the improvement in ejection fraction correlated with the number of CD34+ and CD133+ cells in the bone marrow information that will be helpful in evaluating and designing future therapies and trials.

"This is the kind of information we need in order to move forward with the clinical use of stem cell therapy," said Emerson Perin, MD, PhD, director of clinical research for cardiovascular medicine at the Texas Heart Institute and the study's lead investigator.

This multi-center study was conducted by the Cardiovascular Cell Therapy Research Network and took place between April 2009 and 2011. At five sites, 92 patients were randomly selected to receive stem cell treatment or placebo. The patients, average age 63, all had chronic ischemic heart disease and an ejection fraction of less than 45 percent along with heart failure and/or angina, and were no longer candidates for revascularization.

"Studies such as these are able to be completed much faster because of the team approach of the network," said Sonia Skarlatos, PhD, deputy director of the division of cardiovascular sciences at the National, Heart, Lung and Blood Institute, and program director of the network.

Bone marrow was aspirated from the patients and processed to obtain just the mononuclear fraction of the marrow. In patients randomly selected to receive stem cell therapy, doctors inserted a catheter into the heart's left ventricle to inject a total of 3 ccs comprising 100 million stem cells into an average of 15 sites that showed damage on the electromechanical mapping image of the heart. Dr. Perin said the procedure is relatively quick and painless, involving only an overnight stay at the hospital.

The study used electromechanical mapping of the heart to measure the voltage in areas of the heart muscle and create a real-time image of the heart.

Houston study shows stem-cell's potential for heart treatment

By Stem Cell Treatment

Houston researchers are reporting that adult stem cells have a modest benefit in younger patients with heart failure, the first large-scale evidence that the controversial yet promising new therapy can be developed to help millions of people with the disease.

In a study presented at a cardiology conference Saturday, Texas Heart Institute doctors presented results of a clinical trial showing that cells derived from patients' own bone marrow produce a small but significant increase in the heart's ability to pump oxygen-rich blood.

"This study moves us one step closer to being able to help patients with severe heart failure who lack other alternatives," said Dr. James Willerson, president of the Texas Heart Institute and the study's principal investigator. "It also points to a future in which stem cells regenerate the heart."

The study did not find improvements in a number of heart function measures, but Willerson and other study leaders said it yielded key information about the specific adult stem cells with the greatest therapeutic potential. The trial used a number of stem cell types.

Transplants limited

About 6 million people in the United States have heart failure, a progressive and eventually fatal disease in which the heart loses the ability to effectively pump sufficient amounts of blood to the body's organs. Better therapy is needed because the limited availability of donor hearts makes transplants an option for only about 2,300 people in the United States annually.

Adult stem cells have become the subject of studies for a variety of conditions - the Texas Heart Institute has many involving the heart - since laboratory research in the late 1990s showed they have the ability to grow into most any kind of tissue. This is the first intermediate-stage study in the United States, characterized by multiple centers and many dozens of patients.

The idea of therapy involving adult stem cells formerly was considered non-controversial, a more ethical alternative to destroying embryos to obtain their stem cells. But it has come under fire recently because it is increasingly being used outside of research studies and for profit, particularly in Texas, where Gov. Rick Perry received it last year for his ailing back. The unregulated activity has prompted complaints to the U.S. Food and Drug Administration and a Texas Medical Board draft policy requiring oversight for any use of experimental drugs.

3.1 percent increase

The new study, presented at an American College of Cardiology conference and to be published in the Journal of the American Medical Association, involved 92 patients at five locations - two-thirds at the Texas Heart Institute - whose hearts were pumping at less than 45 percent of capacity and could not be treated with surgery. Doctors injected patients' own stem cells or placebos into their hearts.

Stem cell, heart heath study

By Stem Cell Treatment

HOUSTON -

Doctors from the Texas Heart Institute at St. Luke's Episcopal Hospital have found that patients with heart failure may be able to repair the damaged areas of the heart with stem cells from the patient's own bone marrow.

Doctors presented the findings at the American College of Cardiologys 61st Annual Scientific Session Saturday.

The results are from a multi-center clinical study that measured the possible benefits of using a patients own bone marrow cells to repair damaged areas of the heart suffering from severe heart failure, a condition that affects millions of Americans.

The study, which was the largest such investigation to date, found that the hearts of the patients receiving bone marrow derived stem cells showed a small but significant increase in the ability to pump oxygenated blood from the left ventricle, the hearts main pumping chamber, to the body.

The expectation is that the study will pave the way for potential new treatment options and will be important to designing and evaluating future clinical trials.

This is exactly the kind of information we need to move forward with the clinical use of stem cell therapy, said Emerson Perin, MD, PhD, Director of Clinical Research for Cardiovascular Medicine at THI, and one of the studys lead investigators.

The bone-marrow derived stem cells are helpful to the injured heart when they are themselves biologically active, added Dr. James T. Willerson, the studys principal investigator and President and Medical Director of THI.

This study moves us one step closer to being able to help patients with severe heart failure who have no other alternatives.

The study was conducted by the Cardiovascular Cell Therapy Research Network, the national consortium to conduct such research funded by the National Institutes of Healths National Heart, Lung, and Blood Institute.

Bone Marrow Stem Cell Therapy Trial – Clues, But No Answers

By Stem Cell Treatment

(RTTNews.com) - An important clinical trial, which evaluated the use of autologous bone-marrow-cell therapy in patients with chronic ischemic heart failure, has failed to meet the prespecified end points of improvement in most measures of heart function, according to the results presented at the American College of Cardiology 2012 Scientific Sessions.

The trial dubbed, FOCUS - a phase II study, is the largest study to date to investigate if a patient's own bone marrow cells improved myocardial perfusion, reduced left ventricular end-systolic volume or enhanced maximal oxygen consumption in patients with coronary artery disease or LV dysfunction, and limiting heart failure or angina. The FOCUS trial was undertaken by the National Heart, Lung, and Blood Institute-sponsored Cardiovascular Cell Therapy Research Network.

Ninety two patients with chronic ischemic heart disease , having a left ventricular ejection fraction of 45% or less, a perfusion defect by single-photon emission tomography, or SPECT, who were no longer candidates for revascularization, were enrolled in the trial. Sixty one patients in the study were administered bone marrow cells through transendocardial injections while thirty one patients were administered placebo.

An assessment of primary endpoints at 6 months has revealed that there is no statistically significant difference between the treatment group and placebo arm in left ventricular end-systolic volume assessed by echocardiography, maximal oxygen consumption, and reversibility on SPECT. The secondary outcomes, including percent myocardial defect, total defect size, fixed defect size, regional wall motion, and clinical improvement, also has not exhibited any difference between the two arms.

However, according to the study authors, exploratory analyses have revealed that left ventricular ejection fraction improved in the treatment group compared with the placebo group by 2.7%.

The authors, led by Emerson Perin, concluded that the findings provide evidence for further studies to determine the relationship between the composition and function of bone marrow product and clinical end points. Understanding these relationships will improve the design and interpretation of future studies of cardiac cell therapy, the authors noted.

The results were published online March 24 in the Journal of the American Medical Association.

Stem cell controversy could see new life with regent election shuffle

By Stem Cell Medical Center

The departure of three University of Nebraska regents this year and the re-election campaign of a fourth is reviving debate over a controversial issue some believe should be laid to rest.

Two of the three departing regents, Chuck Hassebrook of Lyons and Jim McClurg of Lincoln, opposed a proposal considered by the Board of Regents in November 2009 that would have limited embryonic stem cell research at the University of Nebraska Medical Center to only cell lines approved under former President George W. Bush. Expansion had become a possibility since President Barack Obama relaxed the Bush guidelines.

Hassebrook and McClurg joined two other regents in killing the proposal by voting against the four who supported it. Pro-life activists believe embryonic stem cell research is morally wrong because harvesting the stem cells requires destroying an embryo.

Regent Randy Ferlic of Omaha, who supported the proposal to limit the research, also will leave the Board of Regents after this year. Bob Whitehouse of Papillion, who opposed the measure, is seeking re-election. Ten candidates are seeking the three retiring regents' seats, and candidate, Larry Bradley, is challenging Whitehouse.

Pro-life advocates said they see opportunity in the departure of two of the regents who opposed limiting stem cell research, but they aren't ready to say they'll ask like-minded regents to reintroduce a proposal to limit the research.

"That would be a place we could stand to gain if we had pro-lifers in the race who we're willing to endorse," said Julie Schmit-Albin, executive director of Nebraska Right to Life.

Nebraska Right to Life endorsed McClurg during his regents campaign, and Schmit-Albin said she believed he would have supported limiting embryonic stem cell research. When he voted against the proposal, however, Nebraska Right to Life ended its support of him, she said.

The group has become more careful in choosing candidates to endorse, Schmit-Albin said, sending out surveys to candidates and incumbents seeking re-election before the primary. It has yet to receive responses from those surveys, she said, so Nebraska Right to Life has yet to endorse any candidates this year.

Schmit-Albin said some regents candidates have contacted the group seeking endorsement, but she declined to name them. She said the group wouldn't endorse Whitehouse because he voted against the stem cell proposal in November 2009.

"He already has a record," she said.

Stem cell therapy could repair some heart damage: Study

By Uncategorized

Published on Mar 25, 2012

CHICAGO (AFP) - Patients with advanced heart disease who received an experimental stem cell therapy showed slight improvements in blood pumping but no change in most of their symptoms, United States researchers said on Saturday.

Study authors described the trial as the largest to date to examine stem cell therapy as a route to repairing the heart in patients with chronic ischemic heart disease and left ventricular dysfunction.

Previous studies have established that the approach is safe in human patients, but none had examined how well it worked on a variety of heart ailments.

The clinical trial involved 92 patients, with an average age of 63, who were picked at random to get either a placebo or a series of injections of their own stem cells, taken from their bone marrow, into damaged areas of their hearts.
