我们重新研究了人类ES和iPS细胞培养的各个组成部分,并制定了一个细胞培养系统,其中液体培养基,附着表面和分裂的所有蛋白质试剂都是化学定义的。一个主要的改进是缺乏血清白蛋白组分,因为动物或人源白蛋白批次中的变化先前已经使人ES和iPS细胞培养物受到不一致的困扰。使用这种新的培养基(E8)和玻连蛋白包被的表面,我们证明了无载体的人iPS细胞与附加体方法的衍生效率提高。这种简化的E8培养基应有利于人ES和iPS细胞及其衍生物的研究使用和临床应用,并应适用于其他重编程方法。
We reexamine the individual components for human ES and iPS cell 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 ES and iPS cell culture with inconsistencies. Using this new medium (E8) and vitronectin-coated surfaces, we demonstrate improved derivation efficiencies of vector-free human iPS cells with an episomal approach. This simplified E8 medium should facilitate both the research use and clinical applications of human ES and iPS cells and their derivatives, and should be applicable to other reprogramming methods.
