本文中我们描述了多光谱成像的应用中，我们描述了作为复用的细胞组合物MIMicc-多光谱询问，以分析肿瘤微环境中的源自骨髓的间质成分，但是这种方法和概念可以应用于破译了组成一个复杂的其他细胞成分组织中，例如在伤口愈合反应或再生组织中看到。在这些实验中，我们利用转基因小鼠中，以荧光从内植入肿瘤微环境中的宿主来源的细胞区分骨髓来源的细胞，但该技术适合于使用任何报告...

了解组织的发育和修复是显著，以阐明在伤口愈合，2,3再生医学，发育生物学，肿瘤生物学参与细胞成分。正在修理的情况下，许多类型的细胞渗透到周围的微环境中血管生成，细胞外基质沉积，增殖和组织结构调整提供帮助。细胞因子和表型可以基于多参数，复用标记，可以识别定位，分化状态和所研究的微环境中的细胞成分之间的相互作用来识别。在这里，我们描述肿瘤的发展作为一个典型的例子为这个多色多细胞移植模型其次是多光谱成像和光谱分离的方法。 肿瘤进展是显着的几个收购功能，包括增强的扩散，一个多步骤的过程ntiapoptotic，浸润和血管生成特性。4肿瘤的发展是由被招募到周围环境中，以提供生长因子，结构基质，血管网络和免疫调节非肿瘤细胞容易。1,5,6这种微生包括衍生自细胞的本地，邻近的组织，例如脂肪，血管和遥远来源如骨髓衍生细胞1。非赘生性细胞结合的程度依赖于来自肿瘤，这往往对应于肿瘤的阶段/级的需求。理解肿瘤微环境中支持的作用，人们必须了解的非肿瘤细胞群的起源和分化潜能。 这个协议被设计在肿瘤进展的同时通过骨髓来源的细胞组分可视化的解释，以帮助和局部组织衍生工编细胞。利用荧光报告基因表达的转基因小鼠，我们移植GFP（绿色荧光蛋白）的骨髓成致死剂量照射的RFP（红色荧光蛋白）鼠标。继成功的骨髓移植，同基因肿瘤细胞系原位注入并允许嫁接4-8个星期。将所得的肿瘤是从小鼠切下并处理用于免疫荧光（IF）染色进行可视化的基质组分。复中频标记是一种常用的技术，它涉及显著优化7-9，不过使用的是多光谱成像/解混平台提高对于具有光谱重叠的荧光标记物的组合的可能性。在此，我们提出我们称之为复用蜂窝组成MIMicc，多光谱审讯染色及分析多达内对单张幻灯片肿瘤部分8标志物，以分析细胞起源，细胞分化ST的技术ATUS和元器件的肿瘤微环境内的细胞 - 细胞相互作用。这个简化的例子有在为了分析五个，六个或更多个标记物，利用抗体或细胞内的启动子驱动的荧光表达， 表1列出潜在荧光抗体染色组合以考虑相应的物种被扩展的可能性。
