In order to avoid the shortcomings of cytotrophoblasts from early first trimester or term villous cytotrophoblast, the differentiated RS366. 4 was used as new early cytotrophoblast model.

为避免由早期胚胎标本或胎盘来源的细胞滋养层细胞模型的不足，本实验选用由猕猴RS366.4 ES细胞来源的早期分化滋养层细胞为模型进行研究。

As we know that human placentalsyncytiotrophoblast cell derlves from the fused cytotrophoblast cell and fetal calfserum can be able to induce the term placental cytotrophoblast cell fusion in vitro.

妊娠过程中，合体滋养层细胞分泌的hCG可促进卵巢黄体和胎盘分泌孕酮，在维持妊娠中起着重要的作用；然而未分化的细胞滋养层细胞不能合成hCGβ。

In general,it was shown that the human cytotrophoblast cells from thefirst-trimester placenta could actively grow,secrete hormones and differentiatemorphologically and functionally under a strict regulation and the PKA,PKC aswell as the MAPK signal transduction pathways mediated the whole process.

总之，本论文表明早孕胎盘细胞滋养层细胞具备活跃的增殖、激素分泌和形态与功能分化能力，这些过程都是在严格的调控下有序进行的，而且PKA、PKC和MAPK信号转导途径担当了重要角色。
