The identification of small molecular inhibitors, which were reported to promote the derivation of mouse and human embryonic stem cells (ESCs), provides a potential strategy for the derivation of domesticated ungulate ESCs. In present study, goat inner cell mass (ICM) derived cells in the double inhibition (2i) condition, in which, mitogen-activated protein kinase kinase (MAP2K) and glycogen synthase kinase 3 (GSK3) were inhibited by PD0325901 and BIO respectively, were characterized. The results showed that goat ICM derived cells in 2i medium adding leukaemia inhibitor factor (LIF) possessed a mouse ES-like morphology. But these cells had much compromised proliferation capacity, resulting in difficulty in expansion. In 2i alone medium, goat ICM derived cells possessed primate ES-like morphology. These cells expressed pluripotent markers and could differentiate into derivatives of three germ layers in vitro. However, these cells could not be proliferated in long-term (persisted for 15 passages) because of spontaneously neural differentiation. Additionally, goat ICM derived cells could be inducing differentiated into neural lineage in vitro. Although goat ESCs could not be established in PD0325901 and BIO alone medium, this derivation condition provides a useful research system to find signaling molecular those regulate early embryonic development and pluripotency in goat.
