How Stem Cells Work
http://science.howstuffworks.com/stem-cell.htm

Their almost limitless potential has made stem cells a significant focus of
medical research. Imagine having the ability to return memory to an
Alzheimer's patient, replace skin that was lost during a terrible accident
or enable a wheelchair-bound person to walk again. But before scientists can
use stem cells for medical purposes, they must first learn how to harness
their power. In this HowStuffWorks article looks at stem cells, find out how
they work, discover their potential to treat disease and get inside the
fierce debate surrounding their research and use.
