VSIG4 and familial pancreatic carcinoma: Macrophages and DCs derived from the bone marrow of wild-type mice showed low proportion of VSIG4 expression, while flow cytometry analysis of pancreatic cancer cell line Panc02-derived tumors supported that the proportion and mean fluorescent intensity of VSIG4 were highest in TAMs compared to DCs, MDSCs and tumor cells (Fig. S1, A-B).
