Object: 74 cases of gestational trophoblast neoplasm.

对象：74例妊娠滋养细胞肿瘤患者标本。

Methods Human trophoblast of early gestation were cultured in vitro.

方法建立人妊娠早期滋养层细胞体外培养体系；

When the trophoblast were removed, ICM cell would be differentiate rapidly.

剥离牛胚胎滋胚层细胞，ICM细胞更易分化。

Villous edema and trophoblast of cell proliferation without clinical significance.

绒毛水肿和滋养叶细胞增生无临床意义。

AIM To prepare highly purified functional human trophoblast cells from human placentae.

目的建立纯度较高的适于试验研究的人绒毛膜滋养层细胞。
