Summary:
LA JOLLA, Calif., – Stem cells are ideal tools to understand disease and develop new treatments; however, they can be difficult to obtain in necessary quantities. In particular, generating induced pluripotent stem (iPS) cells can be an arduous task because reprogramming differentiated adult skin cells into iPS cells requires many steps and the efficiency is very low – researchers might end up with only a few iPS cells even if they started with a million skin cells. A team at Sanford-Burnham Medical Research Institute (Sanford-Burnham) set out to improve this process. In a paper published February 1 in The EMBO Journal, the team identified several specific microRNAs (miRNAs) that are important during reprogramming and exploited them to make the transition from skin cell to iPS cell more efficient.
