  研究方向

1. 干细胞维持基因组稳定性的特征和分子调控研究

干细胞是机体发育和组织稳态维持的基础,其基因组的稳定维持对正常发育及组织器官的稳态维持至关重要。由于功能特殊,干细胞在基因组稳定性调控上有其独特的特征和机制。我们以胚胎干细胞和神经干细胞为对象,研究干细胞调控基因组稳定性的特殊分子机制。这些研究将有助于推动干细胞的安全应用,并有助于理解相关发育异常和疾病的致病机理。

2. 生殖干细胞的基础和应用研究

雌性生殖细胞的再生研究:哺乳动物雌性配子的发生是否存在再生机制一直是生殖生物学领域长期争议的话题,目前尚没有确凿的证据支持生理状况下存在卵巢生殖干细胞及其再生功能。我们以小鼠为模型,通过遗传手段着重研究生理状态下是否存在卵细胞的再生现象,并研究再生的细胞基础。

雄性生殖干细胞研究:树鼩(类灵长类动物)和猕猴(非人灵长类)与人的亲缘关系接近。我们重点研究树鼩和猕猴的精原干细胞的分子特征和体外长期扩增培养体系,并利用精原干细胞系进行基因修饰,创建疾病动物模型,模拟和研究人类疾病。

3. 灵长类早期胚胎发育

由于伦理原因,人类自身的发育过程一直都非常不清楚,特别是早期胚胎的发育调控。利用云南的灵长类资源,我们开展了猕猴着床前后早期胚胎发育的研究,重点探讨发育多能性调控、早期细胞命运分化及胚层发生。这些研究有望为干细胞及转化研究提供核心理论基础,也有助于理解和防范人类胚胎发育异常和失败。
