Quantitative analysis of the origin of stromal elements.

Table representing the quantitative analysis of the origin of stromal elements. α-SMA+, NG2+, FAP+, FSP+, CD31+, and F4/80+ populations within the tumor microenvironment were analyzed for GFP and RFP co-staining. Numbers represent the percent of the indicated stromal population that were bone marrow derived (GFP+) or non-bone marrow derived (RFP). The percentages were averaged among 3 different animals and are displayed as average +/− standard deviation. P-values (*p<0.0001) were obtained by Student's t-test, N represents total number of nuclei per cluster of images (180,000).
