We re-examine the individual components for human embryonic stem cell (ESC) and induced pluripotent stem cell (iPSC) culture and formulate a cell culture system in which all protein reagents for liquid media, attachment surfaces and splitting are chemically defined. A major improvement is the lack of a serum albumin component, as variations in either animal- or human-sourced albumin batches have previously plagued human ESC and iPSC culture with inconsistencies. Using this new medium (E8) and vitronectin-coated surfaces, we demonstrate improved derivation efficiencies of vector-free human iPSCs with an episomal approach. This simplified E8 medium should facilitate both the research use and clinical applications of human ESCs and iPSCs and their derivatives, and should be applicable to other reprogramming methods.6 e. o9 B0 {6 X& v" y

我们实验室正在我的倡导下用这种E8培养基 呵呵 $ v: i/ a* f- G7 S5 F h; [: V实验室韩国小妹做了E8与mTeSR的对比试验,结果发现这两种培养液对细胞生长形态等的影响都基本一致0 I1 @4 `* `! A
现在主要问题是看看bFGF和胰岛素的价格(如果大量购买)能不能有折扣 - c7 E+ z5 N5 u* i7 D& H. X如果没有折扣这种培养基和mTeSR价格差不了太多
