Immunofluorescent/confocal microscopy analysis of distribution of CD68 and stabilin-1 in human breast cancer samples of all stages demonstrated presence of three cell subpopulations: CD68+Stab-1− (Figure 2A and Supplementary Figure 2A), CD68−Stab-1+ (Figure 2B and Supplementary Figure 2B), and CD68+Stab-1+ (Figure 2C, Supplementary Figure 2C). This evidence concerns the gene STAB1 and breast carcinoma.
