MRC1 and neoplasm: The anti-inflammatory M2 phenotype (CD206) was predominant in the tumor edge regions, with a decrease in expression from 1 week to 2 weeks, corroborating the finding by Yuancheng et al. [29], who identified greater CD206 immunofluorescence expression in M2 macrophages compared to M1 macrophages in an M1/M2 induced model in 4T1 cells.
