We aimed to study the physiological mechanisms underlying placental trophoblast differentiation and the correlation with pregnancy complications and diseases, with a focus on the key events including trophoblast primary syncytialization (the first cell-cell fusion event after fertilization), secondary syncytialization (a continuous fusion event creating the largest syncytia across species) and invasion/migration by using placenta-specific knockout mice, live-cell imaging, high-throughput proteomics, single cell RNA sequencing and various cell or tissue models. we focus on investigating the pathological dysfunction and physiological aging of the ovary. The pathogenesis and treatment of ovarian dysfunction, especially premature ovarian insufficiency, are of interest to us. We are also studying the mechanisms that regulate normal ovarian physiological aging to find the secret of senility. In addition, building a complete data model of follicle number with age is an important challenge in understanding ovarian reproductive aging. The aims of these works are to understand the ovarian physiology and to promote the theoretical development and clinical transformation of the treatment of ovarian diseases and fertility recovery in women. Primate’s early embryogenesis is another subject we focused on, especially at the post-implantation stage. Due to the inaccessibility of post-implantation embryos, the limitation of detection techniques and research ethic, developmental events of primate embryos still maintains poorly understand. Here, we established an in vitro culture (IVC) system that supports the continuous development of cynomolgus monkey blastocysts beyond early gastrulation and to 20 days post fertilization. The IVC embryos highly recapitulated the key events of in vivo early post-implantation development without the maternal supporting This study provided important theoretical basis for human embryos gastrulation and related diseases. Based on these research background, we will further optimize the long-term IVC system, and promote primate (non-human) embryos to more advanced developmental stage to discuss more possibilities of life. ![](./201402/W020210615809266452018.jpg) Xiao Z, et al.

Fine-Tuned and Cell-Cycle-Restricted Expression of Fusogenic Protein Syncytin-2 Maintains Functional Placental Syncytia. Cell Reports. 2017 | Plain english: Our group is committed to the study of female reproductive health. We focused on the molecular mechanism of early embryonic development, placental development and pregnancy maintenance, and the relationship between ovarian function and pregnancy outcome: (1) early embryonic development is closely related to successful pregnancy. We used human, cynomolgus monkey and mouse models to study the pathogenesis of early embryonic development, placental development and related diseases (2) Normal mammalian folliculogenesis is a reliable guarantee for the periodic discharge of healthy and fertile eggs. Abnormal follicular activation can lead to reproductive diseases such as premature ovarian failure (POF) and polycystic ovary syndrome (PCOS), which seriously threaten women's health. We used mouse and primate models as well as clinical human disease resources to reveal the molecular mechanisms of follicular development and fertility maintenance.
