Neural induction of porcine-induced pluripotent stem cells and further differentiation using glioblastoma-cultured medium.

ABSTRACT: Prior to transplantation, preclinical study of safety and efficacy of neural progenitor cells (NPCs) is needed. Therefore, it is important to generate an efficient in vitro platform for neural cell differentiation in large animal models such as pigs. In this study, porcine-induced pluripotent stem cells (iPSCs) were seeded at high cell density to a neural induction medium containing the dual Sma- and Mad-related protein (SMAD) inhibitors, a TGF-β inhibitor and BMP4 inhibitor. The dSMADi-derived NPCs showed NPC markers such as PLAG1, NESTIN and VIMENTIN and higher mRNA expression of Sox1 compared to the control. The mRNA expression of HOXB4 was found to significantly increase in the retinoic acid-treated group. NPCs propagated in vitro and generated neurospheres that are capable of further
