Although it is well known that superovulation operations can disrupt uterine function, our understanding of the morphological changes in the uterine endometrium at the three-dimensional (3D) level is limited. Here, combining the tissue clearing with 3D deep imaging, we reveal an increase in epithelial density and angiogenesis after ovarian stimulation, which is accompanied by a circulating surge in P4 levels. Using an ovariectomized mouse model, we further detected the separate regulatory effects of P4 and E2 on the uterine endometrium, with P4 promoting endothelial cell growth and E2 inducing epithelial proliferation. Additionally, we observed that the effects of E2 can be partially neutralized by P4, and vice versa. By analyzing the 3D uterine imaging, we discovered an interesting phenomenon in which the growing blood vessels closely surround the remodeling uterine epithelium, indicating a close relationship between angiogenesis and epithelial growth. These findings provide new insight into the uterine epithelial changes and angiogenesis at the 3D level, and explain a potential reason for endometrial changes due to the low implantation rate in patients undergoing clinic super-ovulation.<\/jats:p>","DOI":"10.3389\/fcell.2022.933852","type":"journal-article","created":{"date-parts":[[2022,6,29]],"date-time":"2022-06-29T08:09:59Z","timestamp":1656490199000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Three-Dimensional Visualization of Mouse Endometrial Remodeling After Superovulation"],"prefix":"10.3389","volume":"10","author":[{"given":"Yongcun","family":"Qu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shanshan","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liwen","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjing","family":"Qian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xili","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enkui","family":"Duan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,6,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"895","DOI":"10.1016\/0093-691x(93)90357-b","article-title":"Fertility and Blood Progesterone Levels Following LHRH-Induced Superovulation in FSH-Treated Anestrous Goats","volume":"40","author":"Akinlosotu","year":"1993","journal-title":"Theriogenology"},{"key":"B2","doi-asserted-by":"publisher","first-page":"4749","DOI":"10.1242\/dev.144386","article-title":"Insights from Imaging the Implanting Embryo and the Uterine Environment in Three Dimensions","volume":"143","author":"Arora","year":"2016","journal-title":"Development"},{"key":"B3","doi-asserted-by":"publisher","first-page":"523","DOI":"10.1056\/nejmoa1513873","article-title":"Fresh versus Frozen Embryos for Infertility in the Polycystic Ovary Syndrome","volume":"375","author":"Chen","year":"2016","journal-title":"N.
