MSR1 and neoplasm: A recent study found MSC-engulfing tumour cells to be characterised by certain up-regulated genes encoding cell surface and extracellular proteins: MSR1 (CD204), WNT5A, ELMO1, IL1RL2 (IL-36), ZPLD1, and SIRPB1 (CD172); in addition, high activity of MSR1 and WNT5A was found to be significantly related to worse metastasis-free survival in cancer patients [90].
