The pan-cancer analysis of single myeloid cells across 15 human cancer types unveiled significant findings, indicating that AMs express genes such as FABP4, MARCO, MRC1( also known as CD206), MSR1 and PPAR-γ, which are involved in self-replenishment through the secretion of (TGF-β [43–45]. Here, TGFB1 is linked to cancer.
