Can heart tissue be regenerated? Mature heart cells, given the right environment, can replicate

Summary:

When human hearts are injured, as during a heart attack, healthy tissue normally can’t regrow. Researchers now demonstrate in rats that a sponge-like patch, soaked in a compound called periostin and placed over the injury, can not only get heart cells to begin dividing and making copies of themselves again, but also improves heart function. Their findings appear in the July 15 online edition of Nature Medicine.
