887-健康人类肝脏空间转录组图谱

from 聊聊Sci

这份研究利用多种先进的空间转录组学技术和单细胞核测序,构建了迄今为止最详尽的健康人类肝脏空间图谱。研究人员通过对比活体捐献者与患病组织邻近样本的差异,指出传统参考样本在基因表达上存在显著偏差。该图谱揭示了人类肝脏在门静脉-中央静脉轴上的功能分区特征,发现人类在代谢功能的空间分布上与小鼠等哺乳动物存在明显跨物种差异。此外,研究还揭示了早期脂肪变性过程中,肝细胞内线粒体基因表达的动态补偿机制。这一成果为理解肝脏生理学、免疫环境以及代谢性肝病的早期演变提供了关键的基准参考。References: Yakubovsky O, Bahar Halpern K, Shir S, et al.
