Stem Cells Show Promise in Repairing a Child’s Heart

Those suffering from a damaged heart can be treated with their own heart cells. According to a recent research, heart stem cells from children with congenital heart disease can rebuild the damaged heart in the laboratory. The findings apparently have great significance in the health zone.

While conducting the research, cells were achieved from patients ranging in age from a few days after birth to 13 years. These patients were previously subjected to routine congenital cardiac surgery. The number of heart stem cells appears greatest in neonates, that reduce with progression in age. Majority of

Stem cells from aged, damaged hearts could be used to treat heart failure

A new research has suggested that cardiac stem cells – even in elderly and sick patients – could generate new heart muscle and vessel tissue and be used to treat heart failure.

Scientists surgically removed tissue from the muscular wall of the heart’s chambers in 21 patients.

They then isolated and multiplied the cardiac stem cells (CSCs) found there.

Most of the patients had ischemic cardiomyopathy (enlarged and weakened muscle due to coronary artery disease). Eleven also had diabetes. The average age of patients was about 65.

“Regardless of the gender or age of the patient, or of diabetes, we were

New clinical trial tests efficacy of stem-cell therapy for stroke

An emergency helicopter trip in May that brought a stroke patient from Forrest General Hospital in Hattiesburg landed the Clarke County resident the first spot in a clinical trial at the University of Mississippi Medical Center for stem-cell therapy.

The new therapy could prevent further brain injury following the initial stroke, preserve vital motor and cognitive abilities and shorten recovery times.

The stem-cell treatment also could add a full day to a narrow four-and-a-half-hour window when current drug treatments work best.
The UMMC Comprehensive Stroke Center is one of 10 U.S. sites enrolling a total of 120 patients into the study. The

Aging heart cells rejuvenated by modified stem cells

Damaged and aged heart tissue of older heart failure External link patients was rejuvenated by stem cells modified by scientists, according to research presented at the American Heart Association’s Basic Cardiovascular Sciences 2012 Scientific Sessions.
The study is simultaneously published in the Journal of the American College of Cardiology.

The research could one day lead to new treatments for heart failure patients, researchers said.

“Since patients with heart failure are normally elderly, their cardiac stem cells aren’t very healthy,” said Sadia Mohsin, Ph.D., one of the study authors and a post-doctoral research scholar at San Diego State University’s Heart Institute

Nanoparticles plus adult stem cells demolish plaque

A technique that combines nanotechnology with adult stem cells appears to destroy atherosclerotic plaque and rejuvenate the arteries, according to a study reported at the American Heart Association‘s Basic Cardiovascular Sciences 2010 Scientific Sessions – Technological and Conceptual Advances in Cardiovascular Disease.

In the study, nanoparticles (microscopic particles with at least one dimension less than 80 nm) were infused into the heart of pigs along with adult stem cells. After the nanoparticles were heated by laser light, they burned away arterial plaque. However, nanoparticles were less effective at eliminating plaque if not combined with adult stem cells.

“This unique
