Supplementary Movies S1 and S2. Distinct imaging of tumor cells, tissue stroma and vasculature.

H2B-mCherry N202 mammary tumor spheroids (red) were implanted on mammary tissue from a GFP mouse (green). 20 days post-implantation, 3D confocal fluorescent microscopy images were constructed of the tumor and tissue stroma as described in the methods.

携带H2B-mCherry标记的N202乳腺肿瘤球状体（呈红色）被移植至绿色荧光蛋白（Green Fluorescent Protein, GFP）小鼠的乳腺组织中。移植后20天，按照实验方法所述，获取了该肿瘤与组织基质的三维共聚焦荧光显微镜图像。
