491-基因网络重构助力干细胞诱导β细胞

from 聊聊Sci

这项发表在《Developmental Cell》上的研究通过整合人类胚胎单细胞测序数据,成功绘制了胰腺发育的基因共表达网络(GCN)。研究人员发现,现有的干细胞诱导方案因未能模拟这种三模块网络结构,导致β细胞诱导效率受限且伴随异向分化。为此,他们开发了一种全新的Protocol D优化策略,通过精确调控早期阶段的Wnt和Activin信号,重建了类似体内的基因网络环境。该方法不仅将诱导周期缩短至19天,还将胰岛β细胞的比例大幅提升至约70%。实验证明,以此方案生成的胰岛在移植入糖尿病小鼠体内后,展现出优异的血糖控制能力与功能成熟度。这一成果为糖尿病的再生医学治疗提供了高效且精准的理论框架与技术路线。References: Yu X X, Wang X, Yang L, et al.
