Abstract
Macrophages not only secure host defense via phagocytosis but also play a key role in tissue homeostasis. A comprehensive study by Fritsch et al. reveals a novel mechanism by which macrophages in the colon deliver polyamines to epithelial cells to support self-renewal of the epithelium during periods of high proliferation.
