滋养层的

STAT3 may be participated in embedded hind film of exuviate of the film inside the patulous, become divided of alimentary layer and uterus changes embryo bubble reaction.

STAT3可能参和植入后胚泡滋养层的扩展、分化及子宫内膜蜕膜化反应。

On the functional differentiation,we found and that the type II ras-GTPaseactivating protein (p100-GAP),which was specifically expressed in humanplacenta,was largely expressed in the highly-differentiated syncytiotrophoblastcells and moderately expressed in the cultured intermediate trophoblast cells.While in the non-differentiated cytotrophoblast cell line-NPC,no expression was observed.Its mRNA and protein expressingcharacterization was in consistent with that of hCGβ,which was one of the mostimportant markers of the trophoblast cell functional differentiation.In addition,the expressing amount of p100-GAP increased with the progressing of pregnancyand the syncytium formation in vitro.

细胞功能分化的研究结果表明：经重组质粒的构建获得特异表达于人胎盘的p100－GAP的cDNA探针后，从蛋白和分子水平证实p100－GAP大量表达于分化程度高的合体滋养层细胞，少量表达于体外培养的中间型滋养层细胞，而非分化的细胞滋养层细胞NPC则不表达，这种表达特性与作为滋养层细胞功能分化重要指标之一的hCGβ高度一致；p100-GAP表达量还随妊娠过程和体外合体化过程而逐渐增加。

These results suggest that flow-induced shear stress regulates the expression of β1 integrin, in turn affects the motility of trophoblast cells.

流动剪切力的参与调节了滋养层细胞β1 整合素的表达，从而可影响滋养层细胞的迁移。

The methods of trophoblast isolation have deficiency of low product ion rate and other cells contamination.

LMWH might regulate cytotrophoblast invasiveness in vitro by influencing the expression of MMP-2 and TIMP-2 in cytotrophoblastic cells.

低分子量肝素可能直接通过影响绒毛滋养层细胞 MMP-2、TIMP-2的表达进而影响绒毛滋养层细胞的侵袭能力。

Uu not only bring out corresponding ultrapathological changes by adhering to the surface of the cytotrophoblast membrane,but also enters the body of the cytotrophoblast and does harm to them directly.

Uu不仅吸附在滋养层细胞膜表面诱发相应的超微病理改变，而且还进入滋养层细胞体内，对滋养层细胞产生直接杀伤作用。

The results from flow cytometry assay showed that the low concentrations of LIF had the ability to shift cytotrophoblast differentiation towards a syncytial pathway, while the high concentrations of LIF towards a invasive pathway.

细胞流式仪结果表明低浓度的LIF可促进绒毛合胞体滋养层的分化，高浓度的LIF可促进绒毛外侵入性滋养层细胞的分化。

Results The expression of ADAM19 are mainly in the cell membrane, plasma and column of cytotrophoblast; The expression of ADAM19 is mainly located on cytotrophoblast during first trimester of pregnancy, and on syncytiotrophoblast in second and third trimester.

结果ADAM19的表达主要集中在滋养细胞的细胞膜、细胞质中和细胞滋养层柱细胞中；早孕绒毛中，ADAM19表达主要集中于细胞滋养细胞膜，在晚孕期胎盘，ADAM19主要表达于合体滋养细胞膜。

From the early study of the pathogenesis of pre-eclampsia people have found its association with immunological function . In 1986 Ellis et al[1] had found that the extravillous chorionic cytotrophoblast contacting with the maternal tissue expressed high levels of Human leukocyte antigen-G, a major histocompatibility tissue-specific antigen . Extravillous chorionic cytotrophoblast with high levels expression of HLA-G proteins can invade the maternal deciduas and the maternal spiral arteries by displacing the endothelial lining and destroying most of the musculoelastic tissue of these arteries .

早期研究开始，许多学者即发现其与免疫学有密切关系，至1986年Ellis等[1]发现人类白细胞抗原(human leukocyte antigen，HLA) G分子高度表达在绒毛外滋养层细胞( extravillous cytotrophoblast，EVCT)上，即浸润至子宫蜕膜层甚至达子宫浅肌层以及子宫螺旋动脉内皮层，与母血及子宫组织直接接触的滋养细胞，这种独特的组织分布提示HLA-G分子在母胎免疫耐受方面起重要作用。
