494-人类性别决定期间性腺体细胞谱系单细胞图谱

from 聊聊Sci

这份研究建立了一个包含12.8万个细胞的人类胚胎及胎儿性腺发育单细胞转录组图谱,涵盖了受精后第5至12周的关键时期。研究者通过该图谱识别出源自体腔上皮的共用原始祖细胞,这些细胞能够分化为支持细胞或类固醇合成细胞。研究进一步揭示了支持细胞谱系在第6周左右确定的性别特异性路径,并发现了卵巢前颗粒细胞分化的双波模型。此外,该研究利用体外器官培养实验,论证了促性腺激素释放激素(GnRH)信号通路在人类早期睾丸分化和基因表达调节中的潜在作用。该资源通过高分辨率的数据分析,填补了人类性腺性别决定初期阶段的研究空白,为理解性别发育异常的分子机制提供了重要参考。References: Lardenois A, Suglia A, Moore C L, et al.
