Breast Tissue (IMAGE) Cell Press Caption This image shows breast sections of a 17 (left) and a 58 year old woman (right) stained for a luminal marker (green) and a myoepithelial/basal marker (red). The luminal cells lose fidelity with age which causes them to appear less luminal and more basal. High-dimensional analysis pinpointed this key age-related change in the luminal population, which may be associated with higher breast cancer risk.
