Stem cells to repair damaged heart muscle
06-21-2007 · EurekAlert!In the first trial of its kind in the world, 60 patients who have recently suffered a major heart attack will be injected with selected stem cells from their own bone marrow during routine coronary bypass surgery.

- Scientists overcome obstacles to stem cell heart repair
12-12-2007 · EurekAlert!
Scientists have overcome two significant obstacles on the road to harnessing stem cells to build patches for damaged hearts. Presenting the research at a UK Stem Cell Initiative conference the researchers will explain how they have made significant progress in maturing beating heart cells derived from embryonic stem cells and in developing the physical scaffolding that would be needed to hold the patch in place in the heart in any future clinical application.

- Human derived stem cells can repair rat hearts damaged by heart attack
08-26-2007 · EurekAlert!
When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal's heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. The researchers also developed a new process that greatly improves how stem cells are turned into heart muscle cells and then survive after being implanted in the damaged rat heart.

- Discovery of cardiac stem cells may advance regenerative heart therapy
11-22-2006 · EurekAlert!
An immediate early publication of the journal Cell, published by Cell Press, on Nov. 22, 2006, points to the possible existence of master cardiac stem cells with the capacity to produce all three major tissues of the mammalian heart. A companion Cell paper also published online reports the discovery of a second population of cardiac progenitors, which are capable of forming both cardiac muscle and the smooth muscle found in the heart's blood vessel walls.

- Mass. General researchers identify master cardiac stem cell
11-22-2006 · EurekAlert!
Researchers from the Massachusetts General Hospital Cardiovascular Research Center have discovered what appears to be a master cardiac stem cell, capable of differentiating into the three major cell types of the mammalian heart. In a report to appear in the journal Cell, receiving early online release, they describe identifying these progenitor cells in mice, cloning them from embryonic stem cells, and showing that cloned cells can differentiate into cardiac muscle, smooth muscle or endothelial cells.

- Human stem cell transplants mature into neurons and make contacts in rat spinal cord
02-13-2007 · EurekAlert!
Human nerve stem cells transplanted into rats' damaged spinal cords have survived, grown and in some cases connected with the rats' own spinal cord cells in a Johns Hopkins laboratory, overturning the long-held notion that spinal cords won't allow nerve repair.

- First human trial tests stem-cell-based treatment for heart attacks
03-25-2007 · EurekAlert!
Previous research on the efficacy of stem cell therapy for heart repair has shown possible benefit from mesenchymal stem cells (MSCs) -- cells found in bone marrow that create connective tissue, bone and cartilage. A study presented today at the American College of Cardiology's Innovation in Intervention: i2 Summit reveals the results of the first human trial using MSCs for the treatment of myocardial infarction (MI, or heart attack).

- Can you hear me now? Stem cells enhance hearing recovery
06-25-2007 · EurekAlert!
Researchers have shown that bone marrow stem cells injected into a damaged inner ear can speed hearing recovery after partial hearing loss. The related report by Kamiya et al, "Mesenchymal stem cell transplantation accelerates hearing recovery through the repair of injured cochlear fibrocytes," appears in the July issue of The American Journal of Pathology.

- Muscle stem cells may offer a new treatment option for congestive heart failure
03-25-2007 · EurekAlert!
As a new wave of stem cell research continues, cardiologists are trying to tap into the self-renewing cells' life-saving potential. Scientists have performed the first US controlled, randomized Phase I clinical trial using a three-dimensional guided catheter system to deliver muscular stem cells to the heart. The study was presented today at the American College of Cardiology's Innovation in Intervention: i2 Summit in New Orleans.

12-11-2007 · EurekAlert!
Doctors are using patients' own bone marrow stem cells (progenitor cells) to treat the damage to cardiac muscle after a heart attack in a study at Emory University School of Medicine. The study investigators will update their colleagues on its progress at the American Society of Hematology meeting in Atlanta next week.
