1251-卵巢衰老的空间转录组图谱
from 聊聊Sci
这项研究通过空间转录组学技术，深入探讨了小鼠卵巢在衰老过程中多细胞协同功能的衰退。研究人员开发了一种新型分割分析方法，精准描绘了卵母细胞、卵泡及黄体在生殖周期中的动态变化规律。实验发现，衰老会导致卵泡发育与排卵周期之间的协调性发生紊乱，这种失调甚至出现在生殖周期停止之前。具体表现为免疫细胞动态改变、炎症信号增强以及组织结构的全局性失序。该成果揭示了微环境组织结构的瓦解是导致生育能力下降的关键因素，为理解卵巢衰老提供了高分辨率的分子图谱。References:Lan T C T, Kochersberger A, Raichur R, et al.
