3本实验小鼠视网膜多潜能干细胞诱导成RPE存在一定困难，但成功建立了一种小鼠ES无饲细胞层培养并添加诱导因子向RPE诱导的高效培养方案。
We failed to induce mouse retinal multipotential stem-like cells into RPE , but have established a stepwise feeder-free culture method of generating RPE from mouse ES cells in vitro with high efficiency .

结果表明：①SDF-1α+SCF+TPO+FL因子组合与SCF+TPO+FL因子组合对脐血CD34+细胞的扩增作用无显著性差异（无论有无MSC细胞层存在）（P>0.05）；
The results showed that as for cord blood cell expansion , there was no significant difference between the groups with cytokines SDF-1 α + SCF + TPO + FL and SCF + TPO + FL no matter MSC layer existed or not .
