Results The expression of endogenous LN was found in the basement membrane of epithelium, glands and blood vessels in uterine endometrium of both estrus and early pregnancy. And its was faint that LN present in basement membrane as the implantation occurs, but the LN immunostaining in the epithelial cells of endometrium was stronger. The exogenous LN has no obvious influence on blastocyst attachment and implantation. LN-antibody intra-uterine injection showed significant repressing effect on mouse blastocyst implantation.

结果 动情期及妊娠早期小鼠子宫内膜内源性LN在上皮和腺基膜及血管内皮基膜均有表达，并随着植入的发生基膜的LN表达减弱，而内膜上皮中LN免疫染色逐渐增强；外源性LN对小鼠胚泡粘附与植入子宫内膜不产生明显影响，层粘连蛋白抗体明显抑制小鼠胚泡着床。

On the other hand, epidermal growth factor , calcium ionophore (A23187), kallikrein and tumor promoter (phorbol-12 myristate-13 acetate) have been shown to stimulate the synthesis of prostaglandins from the thymic epithelial cells.

在另一方面，表皮生长因子、钙离子载体（A〓3817）、激肽释放酶和肿瘤启动子却能促进胸腺内分泌上皮细胞中前列腺素的合成。

To investigate the mitogenic effects of urotensinⅡ on renal tubular epithelial cells in rats.

UⅡ对体外培养的大鼠肾小管上皮细胞具有促丝裂作用。

Both Na2SeO3 and Na2SeO3Vitamin C could obviously inhibit mitoses of vaginal epithelial cells(P＜0.05), but no statistically significance was found between them and the positive control group.

亚硒酸钠及亚硒酸钠-维生素C的各剂量组均可显著抑制小鼠阴道上皮的有丝分裂（P＜0.05），不同剂量的亚硒酸钠组间及亚硒酸钠-维生素C组间与阳性对照组间差异无统计学意义。
