Objective To show the effect of human chorionic gonadotrophin on the expression of invasion associated genes in choriocarcinoma cells.

滋养层细胞来源的绒癌细胞对组织具有浸润能力，这一行为与其表达和分泌基质金属蛋白酶以降解细胞外基质有关[1] 。

Objective To establish a method for the cultivation of keratinocytes in human dermal fibroblast feeder layer.

目的探索和建立人皮肤成纤维细胞滋养层培养人角质形成细胞的技术方法。

On day 10.5, trophoblast giant cell expressed both TIMP-1 and TIMP-3 mRNA, which may be consistent with their functional switch. So it is reasonable to suggest that MMP-2, TIMP-1 and TIMP-3 play an important role in the process of mouse placentation.

所以，MMPs和TIMPs在小鼠滋养层细胞和子宫蜕膜中的协同表达表明其在着床过程中可能发挥重要作用。

There was no proof yet on the expression of NKG2D ligand-MICA on trophoblast.

在滋养层组织未检测到其相应配体MICA mRNA的表达。

Objective To investigate the potential role of tumor necrosis factor-α and interferon -γ in inducing apoptosis of human trophoblast during early pregnancy and its mechanism.

目的 探讨肿瘤坏死因子α与γ干扰素诱导妊娠早期人绒毛膜滋养层细胞凋亡的作用及其机理。

We wished to determine whether infectious HBV can traverse a polarized trophoblast monolayer.

我们希望能确定感染性乙肝病毒能否穿越极化的单层滋养层。

Objective To investigate the effect of human chorionic gonadotrophin on matrix metalloproteinase-19 (MMP-19) mRNA expression in trophoblasts.

目的 观察人绒毛膜促性腺激素对滋养层细胞基质金属蛋白酶 MMP-19表达的影响。

In the normal uterus, Cytokeratins immunolabelling were detected in glandular cell, luminal epithelial cell, Vimentin immunolabelling were detected in stromal cell and endoblastic cell; CK7 immunolabelling were not detected in any tissue of the yak utenus.

研究结果显示：未妊娠时，泛角蛋白在子宫内膜腺上皮细胞、腔上皮细胞内表达，波形蛋白在子宫内膜基质细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，牦牛子宫任何部位均不表达角蛋白7；妊娠30天左右时，泛角蛋白在子宫内膜腺上皮细胞、子宫内膜腔上皮细胞、滋养层细胞、内胚层细胞和尿囊细胞内表达，波形蛋白在子宫内膜基质细胞和内胚层细胞内表达，平滑肌肌动蛋白在子宫平滑肌和血管平滑肌内表达，角蛋白7在尿囊细胞内表达，偶尔在腔上皮细胞的细胞核边缘表达；消化法进行原代培养时，组织经胶原酶消化并通过100目和400目筛网组合可以有效地分离原代子宫内膜基质细胞和子宫内膜腺上皮细胞；分离得到的子宫内膜基质细胞活率达90%以上，并可在体外传代7次以上；分离得到的子宫内膜腺上皮细胞活率可达85%以上，并可在体外传代5次以上；RPMI1640培养基最适合子宫内膜基质细胞和子宫内膜腺上皮细胞的生长，维持子宫内膜基质细胞正常生长的FBS添加量为20%，维持子宫内膜腺上皮细胞正常生长的胎牛血清添加量为30%。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
