REPAIRING HEARTS WITH STEM-CELL INJECTIONS:

British scientists have been given the go-ahead to begin potentially ground-breaking experiments using injections of stem cells to repair patients’ damaged hearts. The team hopes to repair the organs of people who have suffered the most severe heart attacks. . . . The team will extract bone marrow from all 60 patients and separate out a class of stem cells that makes up 1% of the tissue. Previous studies have suggested that this cell type is able to regenerate heart muscle cells and blood vessels. By using the patient’s own cells there will be no problems with tissue rejection.

I hope it works.
