MRC1 and neoplasm: F4/80+ cells isolated from SR-Sor tumour were slightly higher than that of SR-DMSO tumour or SS-DMSO tumour but no statistical difference (SR-Sor versus SR-DMSO or SR-Sor versus SS-DMSO, P > 0.05); however, F4/80+/CD206+ double positive cells isolated from SR-DMSO tumour were significantly higher than that of SR-Sor tumour or SS-DMSO tumour (either SR-DMSO versus SR-Sor or SR-DMSO versus SS-DMSO, P < 0.05), highlighting the role of M2-like TAMs in sorafenib resistance.
