CD47 and neoplasm: Despite the significant tumor heterogeneity among these samples, a majority of αvβ3+ cells overlapped with CD47+ cells in the tumor tissues of G15 (with more parenchymal but less interstitial tissue) (Figure 1E), G11 (almost entirely with tumor parenchyma) (Figure S2B, Supporting Information), and F12 (with less tumor parenchyma but more interstitial tissue (Figure S2C, Supporting Information).
