In this study, imaging mass cytometry was used to chart the multicellular dynamics of breast tissue with age. The spatial distribution of 40 proteins in normal tissues from 527 women shows that the density of cells and their proliferation diminish as the breast ages, and that the proportion of inflammatory immune cells increases.
