CD68 and adenocarcinoma: The staining employed 520 nm wavelength green fluorescence for αvβ3‐positive (αvβ3+) cells, 570 nm red fluorescence for CD47‐positive (CD47+) cells, 650 nm sky blue for CD68‐positive (CD68+) macrophages, and 690 nm grayish purple for CK‐positive (CK+) adenocarcinoma cells (Figure 1D, during processing, 8 paracarcinoma/normal tissue samples were detached; Figure S2A, Supporting Information).
