植入是生殖过程中的重要环节,是妊娠的关键。植入包括胚泡在子宫内膜上的定位、黏附和侵入,以及随后子宫内膜的修复。植入需要有接受态的内膜和功能正常的胚泡,以及二者之间的相互识别。胚泡植入的调控机制十分复杂,研究表明,这一过程是由子宫局部激素-免疫-细胞因子及黏附分子 Implantation is an important part of the reproductive process, is the key to pregnancy. Implantation includes the location, adhesion and invasion of blastocysts on the endometrium, and subsequent repair of the endometrium. Implantation requires an acceptable endometrial and functional blastocyst, as well as mutual recognition between the two. The regulation of blastocyst implantation mechanism is very complex, studies have shown that this process is by the uterine hormones - immune - cytokines and adhesion molecules
