2种鱼的区别主要在于骨块的形状、大小差异及嵴的发达程度的不同。

Results The hEFs were successfully isolated and cultivated from gonadal ridges and dorsal mesenteries of human embryos. They could be passaged beyond the 25th generation. The biologic characteristics of the cells did not change, even in high-passage cells or frozen-thawed cells. The cells expressed prolyl 4-hydroxylase β, but not cytokeratin-4, which was similar to the fibroblasts. The cultured cells expressed bFGF and LIF.

结果：从人胚胎生殖腺嵴和肠背系膜中成功地分离培养出hEFs，该细胞可传25代以上，且经过传代及冻存复苏后生物学特性无改变；hEFs表达脯氨酰4-羟化酶β亚单位，不表达细胞角蛋白4，确定其为成纤维细胞；该成纤维细胞表达bFGF和LIF。
