Promoting Pluripotency

A specialized mammalian cell can be set back to the pluripotent state either by transfer of the somatic cell nucleus into an oocyte or by delivery of exogenous pluripotency-associated transcription factors. Hou et al. (p. 651, published online 18 July) developed an approach to induce pluripotency in somatic cells using a cocktail of small molecules. The ability to generate such chemically induced pluripotent stem cells may provide an alternate route for therapeutic cloning and for drug development in regenerative medicine.

Abstract

Pluripotent stem cells can be induced from somatic cells, providing an unlimited cell resource, with potential for studying disease and use in regenerative medicine. However, genetic manipulation and technically challenging strategies such as nuclear transfer used in reprogramming limit their clinical applications. Here, we show that pluripotent stem cells can be generated from mouse somatic cells at a frequency up to 0.2% using a combination of seven small-molecule compounds. The chemically induced pluripotent stem cells resemble embryonic stem cells in terms of their gene expression profiles, epigenetic status, and potential for differentiation and germline transmission. By using small molecules, exogenous “master genes” are dispensable for cell fate reprogramming. This chemical reprogramming strategy has potential use in generating functional desirable cell types for clinical applications.
