1367-单细胞全转录组异构体空间成像研究

from 聊聊Sci

这篇研究论文介绍了一种名为 RT&T-AMP-MERFISH 的新型空间转录组学成像技术。通过结合原位 RNA 扩增与多重抗错荧光原位杂交技术,研究人员在单细胞分辨率下实现了对小鼠大脑中约 33,000 种 RNA(包括 23,000 个基因和 10,000 个异构体)的成像。该技术突破了以往难以同时兼顾全转录组覆盖度、单细胞空间精度和异构体解析能力的局限。利用这一工具,科学家成功绘制了精细的空间细胞图谱,揭示了基因表达程序、细胞间通讯以及异构体在不同脑区和细胞类型中的特异性分布。这项突破性成果为深入探索组织功能的分子基础和生物体复杂调控机制提供了强大的技术平台。References:Cohen L, Halpern A R, Blosser T R, et al.
