Studies: Stem cells reverse heart damage - CNN.com
The results were striking. Not only did scar tissue retreat — shrinking 40% in Ken Milles, and between 30% and 47% in other test subjects — but the patients actually generated new heart tissue. On average, the stem cell recipients grew the equivalent of 600 million new heart cells, according to Marban, who used MRI imaging to measure changes. By way of perspective, a major heart attack might kill off a billion cells.
