The aim of this study was to investigate the presence of MMP-14 and MMP-2 during human ovarian follicular development using immunohistochemistry, and the activity of MMP-2 in follicular fluid using zymography.
Ovarian tissue collected from the archives of the Department of Pathology was examined and medical records and histopathology were reviewed. Follicular fluids were collected at the IVF-department and analyzed using zymography.
MMP-14 and MMP-2 were increasingly found in the growing follicles and MMP-2 was highly expressed in the corpus luteum. Pro-MMP-2 was present in follicular fluid of IVF-patients.
The presence of MMP-14 and MMP-2 during human ovarian follicular development from the primordial follicle to the tertiary follicle and corpus luteum is confirmed, as was indicated by earlier animal studies following stimulation with gonadotrophins.
本研究旨在采用免疫组织化学方法调查人卵巢卵泡发育过程中基质金属蛋白酶-14(MMP-14)和基质金属蛋白酶-2(MMP-2)的存在情况,并采用酶谱分析法检测卵泡液中MMP-2的活性。
检查从病理科档案中收集的卵巢组织,并查阅病历和组织病理学资料。在体外受精科收集卵泡液,并采用酶谱分析法进行分析。
在生长卵泡中越来越多地发现MMP-14和MMP-2,且MMP-2在黄体中高表达。原MMP-2存在于体外受精患者的卵泡液中。
正如早期用促性腺激素刺激后的动物研究所示,证实了从原始卵泡到三级卵泡及黄体的人卵巢卵泡发育过程中存在MMP-14和MMP-2。
