研究概述
女性生殖健康是当今社会面临人口老化的重要焦点之一。卵子和胚胎发育异常是造成女性不育、流产和唐氏综合症等遗传疾病的主要成因。过往我们在卵子发生和早期胚胎发育已取得了多项开创性的发现:
第一,我们解析了哺乳动物卵母细胞染色质结构重塑的分子机制(Wang et al. Nat. Commun. 2025)。在卵母细胞生长的过程中,其染色质会从疏松的非包绕核仁(NSN)型转变成紧凑的包绕核仁(SN)型,与此同时其转录的活性会大幅度下降,过往的研究普遍认为两者均为表观遗传变化所驱动。有趣的是,我们意外发现这两现象均为RNA聚合酶II在发育过程中天然降解所直接驱动的,且转录沉默独立于染色质结构重塑。结合多组学分析和生物物理实验,我们首次提出RNA聚合酶II的解离增加了染色质的动态并改变了核仁的表面特性,从而驱动NSN-SN型转变的生物物理框架。
第二,我们发现了哺乳动物卵母细胞组装无中心体纺锤体的新原理(So and Seres et al. Science 2019)。哺乳动物卵母细胞在无中心体结构的前提下依然表达了多种中心体蛋白。这些中心体蛋白在减数分裂的过程中会发生一个名为液液相分离的生物物理现象,形成过往未被报导过的液状纺锤体结构域。液状纺锤体结构域在纺锤体微管附近收纳并调动微管调控因子,从而在无中心体下促进纺锤体组装。此外,我们揭示了人类卵母细胞纺锤极组装和不稳定性的分子机制(So et al. Science 2022)。在无中心体的前提下,人类和其他哺乳动物的卵母细胞同样顺利获得NUMA招募动力蛋白到微管负端来聚焦纺锤极。然而,除了人类以外,其他哺乳动物的卵母细胞并没有组装不稳定的纺锤体。利用反向遗传学筛选,我们鉴定出纺锤体稳定性取决于一个名为KIFC1的负端定向驱动蛋白。哺乳动物的卵母细胞大多高度表达KIFC1,唯独人类卵母细胞缺乏KIFC1。顺利获得引入外源的KIFC1蛋白,我们成功的提高了人类卵母细胞组装纺锤体和分离染色体的准确性,首次为防治卵子染色体数目异常带来了可能。
第三,我们阐明了人类着床前胚胎停滞的细胞生物学机制(Li et al. 球友(中国)qy 2026)。临床上有超过一半的人类受精卵会在五天体外培养的过程中停滞,尽管过往已针对性的绘制了大量相关的多组学图谱,但其根本原因未明。顺利获得建立新型的光片显微镜和配套的活细胞标记和图像处理方法,我们首次实现人类着床前发育的完整成像并发现前三天(卵裂期)的停滞为染色体异常所驱动,而第四天(桑葚胚期)的停滞为内质网应激响应所驱动。进一步分析揭示人类二细胞期胚胎易发随机性的中心粒复制错误,继而导致多极纺锤体组装和染色体分离错误。利用半抑制浓度的中心粒复制调控激酶抑制剂,我们成功干预二细胞期卵裂球的中心体数目异常,首次为防治早期胚胎停滞带来了可能。
未来我们实验室会继续利用不同哺乳动物模型(小鼠、大动物、非人灵长类和人类),结合国际领先的显微成像技术(如光片活细胞成像、膨胀成像、组织透明化成像)、功能丧失(如Trim-Away、miniTrim-Away)、生物物理(如力生物学测量、建模)等技术,从不同角度探索卵子和胚胎发育的新机制。我们的研究成果将为女性不育的成因和防治给予新方向,并改善现有辅助生殖技术的效率和安全性。
