Figure 1From: Tumor-specific expression of αvβ3 integrin promotes spontaneous metastasis of breast cancer to boneαvβ3 integrin expression in tumor lines of the metastasis model. Cell surface expression of integrin subunits was determined by measuring the specific fluorescence by flow cytometry as described in Materials and methods. Shaded area, isotype; dotted line, αv; solid line, β3.Back to article page
