Cellular reprogramming: a new technology frontier in pharmaceutical research.

Induced pluripotent stem cells via cellular reprogramming are now finding multiple applications in the pharmaceutical research and drug development pipeline. In the pre-clinical stages, they serve as model systems for basic research on specific diseases and then as key experimental tools for testing and developing therapeutics. Here we examine the current state of cellular reprogramming technology, with a special emphasis on approaches that recapitulate previously intractable human diseases in vitro. We discuss the technical and operational challenges that must be tackled as reprogrammed cells become incorporated into routine pharmaceutical research and drug discovery.
