VEGFB and neoplasm: The secreted factors induced by BCAM in tumor cells, and indirectly through the tumor cell secretome in mesothelial cells, likely cooperate to promote angiogenesis, e.g. through VEGFB [85] produced by tumor cells, CXCXL8 [86] expressed by mesothelial cells and FGF2 [87] secreted by both cell types.
