Abstract
We describe a platform to derive, culture, and differentiate genomically stable, transgene-free human induced pluripotent stem cells (iPSCs) on a fully synthetic polymer substrate made of a grafted zwitterionic hydrogel: poly2-(methacryloyloxy)ethyl dimethyl-(3-sulfopropyl) ammonium hydroxide (PMEDSAH). Three independent transgene-free iPSC lines derived in these conditions demonstrated continuous self-renewal, genomic stability, and pluripotency in vitro and in vivo after up to 9 months of continuous in vitro culture on PMEDSAH-grafted plates. Together, these data demonstrate the strength this alternative platform offers to generate and maintain human iPSCs for regenerative medicine. ©AlphaMed Press.Entities:
