We then evaluated the correlation between CCR2/MSMP expression and macrophage infiltration in ovarian cancer and found that CCR2 expression was significantly correlated with M1-like and M2-like macrophage infiltration (p < 0.001), whereas MSMP expression significantly correlated with only M2-like macrophage infiltration (p < 0.01) (Supplementary Fig. 1C, D). This evidence concerns the gene MSMP and ovarian carcinoma.
