Stem cells used to mend the hearts of rats

In a recent release of research, human embryonic stem cells were found to thrive and actually repair the damaged heart of rats. Does this latest experiment give more proof that stem cells could be used to banish many human ailments? I think that ship has already sailed, but this latest research will being even more questions into the fold about the possibility of stem cell use in the near future.

If it was found that stem cells were actually capable of repairing human heart tissue after disastrous heart attacks and heart failure, stem cell research would find a new following. After all, heart disease is the single largest killer in the U.S.

Already, some want to commercialize this research, like Geron Corp. Geron wants to address the large, yet unmet need in repairing the ravages of heart disease.
