From: Molecular analysis of metastasis in a polyomavirus middle T mouse model: the role of osteopontin
Immunohistochemical analysis of osteopontin (OPN) in the Met and Db tumor tissues. Sections from 10 Met tumors and from 10 Db tumors were stained using immunohistochemistry with antimouse OPN antibody. Representative sections are shown. (a) The Met tumor shows diffuse cytoplasmic OPN staining in the tumor cells, particularly in the periphery of the tumor. (b) The Db tumor cells generally did not stain for OPN.
