图12. 筛选最佳嘌呤霉素浓度
A:sUMSCs(50×);B:1.5μg·mL-1 嘌呤霉素筛选48h后sUMSCs(50×);C:嘌呤霉素筛选结束时sUMSCs(50×)
(在汇合度为70%-80%的sUMSCs中加入抗性,记录细胞几乎全部死亡的时间和浓度作为后续抗性筛选依据)

A: sUMSCs(50×); B: After 1.5μg·mL-1 puromycin screening for 48h sUMSCs(50×); C: At the end of puromycin screening sUMSCs(50×)
(Add puromycin to sUMSCs when the confluence was 70%-80%, and record the time and concentration of almost all cell death as the foundation for subsequent resistance screening. )
