IGF1R expression by epithelial cells in normal urothelium and bladder tumors. (a)Anti-IGF1R immunohistochemistry from human protein atlas project ( http://www.proteinatlas.org/ ). 3 examples of representative staining in tumors are presented in the right panel, staining of the two normal samples are presented in the left panel. Scale bar represents 100 μm (b) Haematoxylin-eosin staining of our CIT-series of tumors. Examples of tumors with high and low IGF1R expression assessed by RPPA. (TIFF 7100 kb
