Tumor-associated macrophages promote tumorigenesis. a Subcutaneous BxPC-3-luc tumors co-inoculated with macrophages tend to grow more rapidly than controls. N = 3/each tumor. Pictures: Representative IVIS imaging on days 21, 35, and 42. b Peritoneal BxPC-3-luc tumors co-inoculated with macrophages grow significantly more rapidly than controls. N = 8/treatment group. * p < 0.01. Pictures: Representative IVIS imaging on day 37
