报道从237枚家兔胚胎中建成7个可连续传代的ES样细胞系。建系条件为,使用小鼠原始胚胎成纤维细胞(ME)作饲养层,以含10%胎牛血清和10%兔血清的DMEM/F12为培养基,添加白血病抑制因子(LIF)或上皮生长因子(EGF),胚龄为90,96h。该细胞系的细胞,在许多方面类似于小鼠ES细胞:具干细胞的形态特征,呈集落型生长,可连续传代并保持其形态特征,具一定的自发分化和诱导分化的能力,悬浮培养可形成简单类胚,但皮下接种同种乳兔未获肿瘤。用所建的兔ES样细胞进行卵母细胞核移植时,有11%发育为囊胚
Seven ES-like cell lines that can be passaged serially were reported from 237 rabbit embryos. The establishment of the conditions for the use of mouse embryonic fibroblasts (ME) as a feeder layer, with 10% fetal bovine serum and DMEM / F12 as a medium, add leukemia inhibitory factor (LIF) or epithelial growth Factors (EGF), embryonic age 90,96 h. Cells of this cell line resemble mouse ES cells in many ways: the morphological features of stem cells are colony-type growth, which can be continuously passaged and maintain its morphological characteristics, with certain spontaneous differentiation and differentiation-inducing ability. Suspension culture can be The formation of a simple embryoid, but the same kind of rabbit subcutaneously vaccinated without tumor. 11% developed as blastocysts when oocytes were nuclear transplanted with rabbit ES-like cells
