该方案描述了使用无酶解离方法收获细胞并将细胞保存在用于人多能干细胞(hPSC)的无白蛋白化学成分确定的E8培养基中的冷冻保存程序。通过EDTA/PBS的解离产生小细胞聚集体,其允许在传代和冷冻保存中的高存活效率。E8培养基中的保存消除了血清或其他动物产品,并且适合转化研究中对高质量hPSC的日益增长的需求。结合EDTA/PBS解离的特殊功能,该方案允许以更节省时间的方式进行有效的冷冻保存。
This protocol describes a cryopreservation procedure using an enzyme-free dissociation method to harvest cells and preserve cells in albumin-free chemically defined E8 medium for human pluripotent stem cells (hPSCs). The dissociation by EDTA/PBS produces small cell aggregates that allow high survival efficiency in passaging and cryopreservation. The preservation in E8 medium eliminates serum or other animal products, and is suitable for the increasing demand for high quality hPSCs in translational research. In combination with the special feature of EDTA/PBS dissociation, this protocol allows efficient cryopreservation in more time-saving manner.
