Feeder cells treated with ethanol can be used to maintain self-renewal and pluripotency of human pluripotent stem cells.

ABSTRACT: Feeder cells play an important role in the culture of human pluripotent stem cells (hPSCs) in vitro. Previously, we used methanol as a fixative to prepare feeder cells for the cultivation of pluripotent stem cells (PSCs), and this method could maintain the self-renewal and pluripotency of PSCs. However, methanol is toxic, and so here we examined whether ethanol could be used to prepare feeder cells as a fixative for hPSC culturing. Primed, naïve, and extended human embryonic stem cells and induced pluripotent stem cells can maintain self-renewal and undifferentiated potential on feeder cells treated with ethanol for an extended period. RNA sequencing analysis showed that the expression of collagen-related genes in hPSCs cultured on feeder cells treated with ethanol was significantly lower
