1290-小鼠胚胎发育细胞与谱系图谱 mdCLA

from 聊聊Sci

这份名为小鼠发育细胞谱系图谱 (mdCLA) 的研究,通过单细胞转录组测序技术,详尽记录了小鼠从二细胞阶段到出生共37个关键时间点的发育全过程。研究者分析了超过两百万个细胞,构建起涵盖108个器官、305种细胞类型及1316个亚型的四级分类系统,其数据深度显著优于现有的同类数据库。利用该谱系图,研究团队揭示了肾原基细胞在不同发育阶段的异质性,并发现了上皮细胞在胚胎后期存在加速分化的现象。此外,研究还验证了特定转录因子在垂体上皮中的调节作用,阐明了其缺失如何导致小鼠产后肥胖。总之,mdCLA为深入理解哺乳动物胚胎发育的动态机制提供了一个极具参考价值的高分辨率转录组参考图谱。References:Cao S, Lin L, Feng H, et al.
