Figure 1From: Tumor associated macrophages polarization dictates the efficacy of BCG instillation in non-muscle invasive urothelial bladder cancerCD68/CD163 expression in M2 macrophage in bladder cancer. A) CD68 (green), shows nucleated cells positive staining for CD68; B) CD163 (red 2), shows CD163 staining in macrophage phenotype; C) DAPI, shows the cell nuclei marked with DAPI; D) merged image of DAPI, CD68 and CD163 showing a number of macrophages with positive staining for the phenotype marker M2.
