主 题:embryonic stem cell neural precursor cell cell culture
摘 要:Objective To investigate whether buffalo rat liver cell conditioned medium (BRL CM) can be used as the culture medium of embryonic stem (ES) cells, and to get relatively pure neural precursor cells (NPCs) for treatment aim. Methods Mouse ES cells were cultured in BRL CM and medium contain leukemia inhibitory factor (LIF), respectively. NPCs were selectively cultured in serum free medium. Alkaline phosphatase activity was visualized with NBT/BCIP and nestin antigen was detected with immunocytochemical methods. Results BRL CM could be used as an efficiency culture condition instead of LIF in ES cells culture. About 86% of cells derived from ES cells in the serum free culture were NPCs. Conclusion BRL CM can replace LIF to use in ES cell culture. High purity of NPC can be induced from ES cells with serum free culture method.
