Investing in Banks of Stem Cells
One of the great benefits of cell reprogramming--converting adult cells into stem cells--is the ability to capture an individual's genetic diversity. Scientists are now using this technology, known as induced pluripotent stem  (iPS) cell reprogramming, to create banks of stem cells from different people. The banks will be used to test the toxicity of different drugs using cells from people of different ethnicities, and could potentially supply cells for tissue replacement therapies. Researchers presented details of their efforts at the International Society for Stem Cell Research conference  in San Francisco this week.
