肿瘤生物学中的多重蛋白成像
在过去的十年里,组织成像变得更加丰富多彩。实验和分析方法的进步使得对组织样品中的蛋白质标记物进行高倍数成像成为可能。在单细胞或亚细胞分辨率( single-cell or subcellular resolution )下同时常规成像40-50个标记物的能力,为肿瘤生物学研究开辟了新的前景。
细胞表型、相互作用、通信和空间组织已经变得适合于分子水平的分析,并且应用于患者队列已经确定了几种癌症类型中临床相关的细胞和组织特征。
今天来了解下多重蛋白质成像( multiplex protein imaging )方法在研究肿瘤生物学中的应用。
Multiplex protein imaging can interrogate a tumour and its microenvironment across scales
Multiplex protein imaging can be applied to clinical cohorts
An overview of spatial analysis approaches for multiplex protein imaging data
The principles of single-cell multiplex protein imaging methods.
Features of multiplex protein imaging technologies
Canonical pipeline for multiplex protein image processing
The principles of spatial multi-omics techniques
如果同时包含细胞外和细胞内事件的标记,甚至可以绘制整个信号循环。由于缺乏对肿瘤组织进行单细胞和深层表型分析的可靠方法,到目前为止,特别是在人类样本中,根本不可能探索这些问题。单细胞分辨( Single-cell-resolved )、多蛋白和多模态成像( multimodal imaging )将突破 这一难点。
