, γδ) and M2-like macrophages expand with age. Spatial transcriptomics reveals co-localization of aged immune and epithelial cells in situ. Lastly, we found transcriptional signatures of aging mammary cells in human breast tumors, suggesting possible links between aging and cancer. Together, these data uncover that epithelial, immune and stromal cells shift in proportions and cell identity, potentially impacting cell plasticity, aged microenvironment and neoplasia risk.
