Research Abstract

マウスは5週齢の性ホルモン分泌急増に伴い皮膚近傍の膣末端部上皮細胞の細胞死(アポトーシス)が誘導され、膣腔が皮膚に貫通(膣開口)する組織リモデリング現象を経て生殖器発達が完成する。私共の解析から、セマフォリン分子群に属するセマフォリン4D(Sema4D)の遺伝子欠損マウスでは、膣開口が起こらず膣閉鎖を発症し、5週齢マウス膣末端部におけるアポトーシス細胞の顕著な減少が明らかになった。2007~2008年度科学研究費研究計画実施の結果、Sema4Dのマウス膣上皮細胞に対するアポトーシス誘導作用が証明され、Sema4Dによるアポトーシス誘導にはPlexin-B1受容体が関与することが判った。
