During female reproductive tract development in mice, the bilateral Müllerian duct epithelium grows caudally until reaching the urogenital sinus epithelium. This is followed by further caudal growth with the reduction of the urogenital sinus epithelium. Finally, the vaginal epithelium of adult mice is entirely derived from the Müllerian duct epithelium. Here, we explored the mechanisms underlying mouse vaginal development via cell proliferation, apoptosis, and lineage analyses. We found that at the late embryonic stages, apoptosis occurred at the attachment site of bilateral Müllerian duct epithelia below the cervix, resulting in bilateral lumen traffic. The Müllerian duct epithelium was enclosed by the urogenital sinus epithelium at their boundary region on embryonic day (E) 16.5, whereas the Müllerian duct epithelium encased the urogenital sinus epithelium at postnatal day (P) 0 through lateral enlargement. Lateral Müllerian duct enlargement was accompanied by focal ERK activation within the curved epithelial tips and the specific localization of mitotic nuclei on the luminal side of the Müllerian duct epithelial layer at E17.5. Descent of the Müllerian duct epithelium and shortening of the urogenital sinus epithelium occurred rapidly after birth, accompanied by cell proliferation in the Müllerian duct epithelium and its peripheral mesenchymal tissues as well as intense apoptosis in the urogenital sinus epithelium around their boundary region. Urogenital sinus epithelium was localized at the base of the vagina at P7. In conclusion, the mouse vagina develops laterally at the late embryonic stages and caudally after birth.</p>","PeriodicalId":10626,"journal":{"name":"Congenital Anomalies","volume":"63 2","pages":"30-39"},"PeriodicalIF":1.3,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cga.12502","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9096261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared two impression methods, conventional impression making and intraoral scanning, to study unilateral cleft lip and palate (UCLP). Patients with UCLP (<i>n</i> = 7) were selected, and palatal impressions were taken by two steps: (1) impressions were obtained using an addition silicone rubber impression material, and a plaster model was prepared and (2) optical impressions were obtained using a desktop three-dimensional (3D) scanner and stereolithography (STL). Data were generated by two impression system combinations through STL. The results were analyzed using the Kruskal–Wallis or Mann–Whitney <i>U</i> test. There were no significant differences in the dimensions of the models between both groups. The measured depth of the alveolar cleft defects was deeper in the plaster model group (STL) than in the intraoral scanner group (STL). Digital models may prevent the risk of aspiration and respiratory disorders by using impression materials for preoperative jaw treatment of newborns and infants. We compared the results of both impression methods in the same patient and found that a shift to the 3D printer model is a safe alternative for preoperative jaw correction, as evidenced from the amount of tissue displaced due to the pressure applied during impression taking. In the future, we would like to conduct clinical research with a larger sample size of CLP patients to further corroborate these findings.</p>","PeriodicalId":10626,"journal":{"name":"Congenital Anomalies","volume":"63 1","pages":"16-22"},"PeriodicalIF":1.3,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cga.12499","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9297908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
