| Title | Generation of Human Induced Pluripotent Stem Cells in the Absence of Exogenous Sox2. | | Author(s) | Li W, Zhou H, Abujarour R, Zhu S, Joo JY, Lin T, Hao E, Schöler HR, Hayek A, Ding S | | Institution | Department of Chemistry, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA. | | Source | Stem Cells 2009 Oct 16. | | Abstract | Induced pluripotent stem cell technology has attracted enormous interests for potential application in regenerative medicine. Here, we reported that a specific glycogen synthase kinase 3 (GSK-3) inhibitor, CHIR99021, can induce the reprogramming of mouse embryonic fibroblasts (MEFs) transduced by only Oct4 and Klf4 two factors. When combined with Parnate (also named tranylcypromine), an inhibitor of lysine-specific demethylase 1, CHIR99021 can result in the reprogramming of human primary keratinocyte transducted with Oct4 and Klf4 two factors. To our knowledge, this is the first time to generate human iPS cells from somatic cells without exogenous Sox2 expression. Our studies suggest that the GSK-3 inhibitor might have a general application to replace transcription factors in both mouse and human reprogramming. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
