Methods LN in mouse endometrium was shown and measured with indirect immunofluorescence techniques, immunohistochemical ABC method and image analysis system. The effect of LN on the implantation was studied by using LN-antibody intra-uterine injection.

应用间接免疫荧光法、免疫组织化学ABC技术及图像分析法进行LN定位和定量测定；利用子宫内注射LN抗体的方法探讨LN对小鼠胚泡植入的作用。

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。
