Additional file 2: of The epithelial-to-mesenchymal transition induced by tumor-associated macrophages confers chemoresistance in peritoneally disseminated pancreatic cancer

Immunohistochemistry of subcutaneous BxPC-3-luc tumors co-injected with or without M2 macrophages. CD204 indicates M2-polarized macrophages, and vimentin indicates cells that underwent the EMT. Immunostaining of a tumor demonstrates expression of vimentin along with CD204 only in the tumor co-injected with M2-polarized macrophages, suggesting that macrophages induce the EMT in vivo (PDF 253 kb
