Understanding and treating disease

MIT News 

In 2006, a discovery opened up a new world of possibility for treating diseases. For the first time, researchers created stem cells without using embryos. Adult skin cells were reprogrammed into induced pluripotent stem cells, or iPSCs, that could differentiate into specialized cells for use in almost any part of the body -- from the liver to the heart or brain, and everywhere in between. Areas of the body damaged by disease could be made healthy again.
