851-人内胚层类器官转录组细胞图谱

from 聊聊Sci

这份研究介绍了一个名为人类内胚层源类器官细胞图谱 (HEOCA) 的大规模单细胞转录组数据库。研究团队整合了来自55项研究的近一百万个细胞数据,涵盖了肠道、肺和肝脏等九种不同的人类器官模型。通过跨数据集的标准化分析,该研究详细比较了由多能干细胞、胎儿干细胞及成人干细胞培育出的类器官在细胞组成和成熟度上的差异。研究证明,该图谱可作为评估实验方案保真度的标准参考,帮助识别类器官中的脱靶细胞。此外,作者利用该工具包成功分析了病毒感染、炎症反应以及结直肠癌等病理状态下的细胞变化。总之,这一集成资源为优化类器官培养技术和建立更精准的人类疾病模型提供了重要的计算框架与数据支持。References: Xu Q, Halle L, Hediyeh-Zadeh S, et al.
