Mr Robin Marston, a 61-year-old bus driver from West Drayton in London, has taken part in a new clinical trial, a pioneering stem-cell program at The Barts and The London Heart Attack Center.

In the first clinical trial of its kind, Doctors took stem cells from bone marrow in lower back of the patient. Mr Marston then received either his own stem cells back or a placebo - the trial requires he does not know which - via a catheter in his groin. The aim of the treatment for those receiving the stem cells is to “turn the clock back” for heart attack victims by repairing damaged heart tissue. The trial, if successful, is likely to involve around 100 more people in near future.

“I feel practically 100% now.” said Robin.

The trial uses adult stem cell from the patients body which is free of any controversy.
