Comparison between in situ and invasive components found in the same patient TMA core. (A) Representative image of an IDC case with in situ component, the latter displaying peripheral integrin αV. Typical in situ component (indicated by an arrow) outlined by integrin αV staining. The invasive component shows almost complete absence of peripheral integrin αV. Scale bar = 100 µm. See supplementary Figure 1 for an additional representative image. (B) Detailed information of 8 cases that had both in situ and invasive components, regarding the presence and intensity of peripheral integrin αV and molecular subtype classification.
