Two elements had been found to become critical for effective derivation and maintenance of rat iPS cells: the usage of rat rather than mouse feeders, and the usage of small substances inhibiting mitogen-activated protein kinase and glycogen synthase kinase 3 pathways specifically. In contrast, launch of embryonic stem cell (ESC) ingredients induced incomplete reprogramming, but didn’t generate iPS cells. Nevertheless, when coupled with retroviral transduction, this technique generated iPS cells with higher efficiency significantly. Morphology, gene appearance, and epigenetic position confirmed that.
