296-PRISM:单轮成像高多重空间RNA成像技术

from 聊聊Sci

本研究介绍了一种名为 PRISM (profiling of RNA in situ through single-round imaging) 的新技术,该方法通过使用 颜色强度条形码 在一次成像中实现高多重空间RNA成像。PRISM克服了传统荧光显微镜通道有限和循环反应依赖复杂仪器的挑战,因为它只需要 常规显微镜 即可工作。研究人员通过应用PRISM,成功构建了小鼠胚胎发育的 三维 (3D) 细胞图谱 和人类肝细胞癌 (HCC) 的 准 3D 微环境景观,揭示了 HCC 微环境中的 异质性 和细胞间的相互作用。此外,该技术还被用于分析完整厚组织中小鼠脑组织的 细胞和亚细胞 RNA 分布,展示了 PRISM 在生物学研究中的 广泛适用性和高通量能力。References: Chang T, Zhao S, Deng K, et al.
