  哺乳动物的妊娠起始于囊胚的滋养层细胞与子宫内膜识别、黏附,并进一步向子宫内膜侵袭,将胚胎锚定在子宫壁上。伴随胚胎发育,胚胎滋养层细胞活跃增殖和分化,对子宫内膜基质和螺旋动脉进行改建和重构,建立完善的子宫-胎盘-胎儿循环,保障胎儿宫内发育。因而,胎盘发育是哺乳动物妊娠成功建立和维持的重要保障。胎盘发育不完善将引起一系列复杂的妊娠相关疾病,如子痫前期、复发流产、胎儿生长受限等,对母儿近远期健康都造成严重危害。

  迄今,对人类胎盘的认识依然是个“黑匣子”,其发育调控机理及其介导的母体妊娠适应性调节机制仍有待阐明,而与之密切相关的妊娠重大疾病的预测、防治和干预也亟待突破。

  本研究组在前沿科学问题和国家重大需求引导下,致力于研究胎盘发育和妊娠维持的调控机制,以及妊娠高血压、复发流产等重大妊娠疾病的发病机理。旨在揭开人类妊娠健康的神秘面纱,并为发展重要妊娠疾病的预测和干预策略奠定坚实的科学基础。

  我们已经建立和稳定了包括不同分化路径的人滋养层细胞培养体系、滋养层细胞-血管内皮细胞三维共培养、滋养层干细胞等体外研究模型,并稳定了CYP19-Cre、ELF5-Cre介导或慢病毒/腺病毒介导的胎盘特异基因操作的小鼠模型,构建了多种妊娠疾病的小鼠模型等。通过与多中心临床单位协作,建立了子痫前期等妊娠重要疾病前瞻性资源库;获得了一批可用于子痫前期早期诊断的分子标志物;对多个分子标志物影响胎盘细胞分化和功能及母体妊娠适应性的机制及其参与子痫前期发生发展的机理进行了深入分析。近期研究发现了mTOR信号介导的滋养层细胞合体化通过巨胞饮方式适应环境营养压力的机制,阐释了蛋白质糖基化修饰调节滋养层细胞分化的路径,揭示了子宫螺旋动脉改建进程中血管内滋养层细胞的免疫调节功能及平滑肌细胞的去分化命运,并通过单细胞转录组分析系统阐释了母胎界面上妊娠适应性的细胞和分子调控网络。

研究内容和目标:
  我们的主要研究兴趣是胎盘发育和妊娠维持的调控机制,并以此为切入点研究子痫前期和复发流产等重大妊娠疾病的病因学。具体的研究内容包括:
  1. 胎盘滋养层细胞发育分化的谱系编程机制;
  2. 子宫-胎盘-胎儿循环的构建机制;
  3. 母胎界面多细胞互作建立免疫适应性的分子基础;
  4. 子痫前期、复发流产等重要妊娠疾病的病因学。
  研究目标是:综合利用临床样本库、体外模型和小鼠模型,将胎盘发育及功能研究与临床重大疾病机制和干预策略探索相结合,揭开人类胎盘发育和妊娠维持调控的分子机理,为发展重要妊娠疾病的预测和干预策略奠定坚实的科学基础。
