Fig. 5. Ex vivo tissue imaging of aggressive carcinomas under multi-colour fluorescence confocal microscopy. Tumour-associated macrophages were stained in green by anti-Iba1 and KRT1+ cells were stained with peptide 8 (5 μM). DAPI was used for nuclear counterstaining (blue). TAM–cancer cell interactions are identified with white arrows. Scale bar: 10 μm.
