Lyoplate analysis of surface marker expression patterns in different mammary epithelial and stromal subpopulations. FACS based expression analysis of 242 surface markers using the BD Lyoplate™ Human Surface Marker Screening Panel on primary human breast cell populations (blue: basal, green: luminal progenitor (LP), purple: mature luminal (ML), orange: stromal). The values represent the mean percentage of positive cells for each surface marker antibody within two pooled donor samples from the two antibody screen replicates. Zero indicated that the percentage of cells ranged from 0 to 1% within the positive gating. CD markers underlined indicate unreported expression in breast epithelial/stromal cells. CD markers with an asterisk indicate less characterised expression in breast epithelial and stromal cells
