Adult stem cell research has been booming. There are so many advances that it is hard to keep up. Just recently researchers were able to take adult human skin cells, convert them back to an embryonic state, and then with a string of chemical cocktails convert them into heart cells that were capable of being transplanted into rats. While not yet ready for human trials, this is a major milestone that may one day give real hope to those who have suffered heart attacks.
