CD209 and sarcoma: Other M2-like TAMs, identified in sarcomas, are, for example, mannose receptor-1 (MMR, CD206), observed in dermatofibrosarcoma protuberans (DFSP), and osteosarcoma, macrophage scavenger receptor 1 (MSR1, CD204), observed in UPS, and dendritic cell-specific ICAM-3 capture non-integrin (DC-SIGN, CD209) and melanoma cell adhesion molecule (MCAM, CD146), observed in osteosarcoma [2,39].
