Abstract
The article presents the research and social implementation efforts undertaken by my colleagues and me at the Department of Obstetrics and Gynecology, Osaka University Graduate School of Medicine. We cloned the human oxytocin receptor using molecular biology techniques and investigated its transcriptional regulatory mechanisms in the human uterus during parturition. Additionally, we adapted a mouse placenta-specific gene expression system to develop a preeclampsia model and explored potential therapeutic strategies. Our research also focused on improving surgical techniques for peripartum hysterectomy in cases of critical obstetric hemorrhage and vasa praevia with placenta praevia, which may also lead to sudden fetal death during parturition. Concurrently, based on epidemiological data, we adopted a social approach strengthening obstetric care teams and identifying key issues within Japan's delivery system. Furthermore, we developed a web-based postpartum care procedure. I hope that research and practices aimed at enhancing maternal safety and well-being will continue to progress further in the future.
