“…The identity of cells can be altered by the forced induction of combination of transcription factors (TFs) (Takahashi and Yamanaka, 2006;Vierbuchen et al, 2010;Ieda et al, 2010;Sekiya and Suzuki, 2011;Huang et al, 2011;Hiramatsu et al, 2011), the forced induction of single TFs (Davis et al, 1987;Nishiyama et al, 2009;Correa-Cerro et al, 2011;Yamamizu et al, 2013) or by the repression of single TFs (Skarnes et al, 2004;Ivanova et al, 2006;Collins et al, 2007;Nishiyama et al, 2013). As an aid to analyze the effects of TF manipulation on mouse embryonic stem cell (ESC) differentiation, we have established the NIA Mouse ESC Bank (Nishiyama et al, 2009;Correa-Cerro et al, 2011), in which each of 137 TFs, i.e.…”
