Polyoma virus middle T cancer cells express activated STAT3 and FR. Immunofluorescent histochemical staining of breast tissue sections from 9-week-old PyMT female mice was performed using antibodies specific for the indicated proteins. The control was incubated with bovine serum albumin (BSA) blocking solution alone, followed by incubation with the secondary antibody. Alexa Fluor (green) is Alexa Fluor-488-conjugated secondary antibody. The nuclei (blue) is stained with DAPI (4',6-diamidino-2-phenylindole). Pictures were processed using Adobe Photoshop CS5.
