Similarly, double staining of tumor sections for pericytes with α-SMA and endothelial cells with CD31 showed little differences over time in the VEH and SUNI groups (Figure 8), except for one noticeable, although not statistically significant, increase of pericytes coverage at W1 in the SUNI tumors (Figure 8E, F). The gene discussed is PECAM1; the disease is neoplasm.
