The effect of feeder cell type, growth factors, and embryo developmental stage on establishment of sheep embryonic stem cell was also studied in present experiment.

同时，比较了饲养层细胞类型、生长因子、胚胎发育阶段等因素对绵羊胚胎干细胞分离培养效果的影响。

Objective: Sepretae Sertoli cell, BMSC, MEF, Pancreatic fibroblast and establish cell lines, constructed different feeder layers for a source as a coculture system for stem cells.

目的： 分离培养睾丸支持细胞、骨髓基质细胞、胚胎成纤维细胞和胰腺成纤维细胞，优化培养条件，建立饲养细胞系，为干细胞体外共培养体系的建立提空充足的饲养细胞。

Scientists found however, that feeder cells and serums derived from other animal cells introduced disease-causing agents that compromised the quality of the cell lines.
