Stem cells from cord blood could help repair damaged heart muscle
Date:10/13/2011

arrow may help with the regeneration of damaged heart muscle.

Professor Jeremy Pearson, Associate Medical Director at the British Heart Foundation, said: "Regenerative medicine research in the lab, alongside studies of patients, is absolutely crucial. Right now, the damage to the heart caused by heart attack cannot be reversed. Through research like this across the UK, we hope to bring our vision of mending broken hearts to reality.

"There has been interest for some time in the potential use of blood from the umbilical cord as a source of stem cells for therapy in a variety of diseases. This study has shown for the first time that it's possible to turn cord blood stem cells into cells that look like heart muscle, in the lab. The results are encouraging, but there are still lots of questions to answer before we'll know whether these cells can be used successfully for heart repair in patients."

In 2007, the British Heart Foundation (BHF) awarded Professor Ascione, over 200,000 for the world's first clinical trial, TransACT, to test whether bone marrow derived CD133+ stem cells can repair heart muscle cells damaged by a heart attack. Recently, funding for the trial has been extended to 2013.

The double blind placebo-controlled trial has successfully recruited 50 per cent of its patients with no safety concerns. Under Professor Ascione's leadership, 31 out of 60 patients, who have suffered a major heart attack, have been injected to date at the Bristol Heart Institute with stem cells from their own bone marrow or a placebo into their damaged hearts during routine coronary bypass surgery.
