Highlights► Signaling in pluripotent stem cells is a complex, dynamic process. ► Multiple signaling pathways are required for maintenance of the stem cell state: Fgf/MAPK, TGFβ/SMAD2,3 and insulin/PI3K. ► These pathways are highly interactive and form a finely-balanced signaling network. ► Thresholds, temporal changes and combinatorial effects make important contributions to cell fate outcomes. 相似文献
