Stromal-epithelial interactions in aging and cancer: senescent fibroblasts alter epithelial cell differentiation
18 Jan 2005
Abstract excerpt
Cellular senescence suppresses cancer by arresting cells at risk of malignant tumorigenesis. However, senescent cells also secrete molecules that can stimulate premalignant cells to proliferate and form tumors, suggesting the senescence response is antagonistically pleiotropic. We show that premalignant mammary epithelial cells exposed to senescent human fibroblasts in mice irreversibly lose differentiated...
