Enteroendocrine cells support intestinal stem-cell-mediated homeostasis in Drosophila.
Intestinal stem cells in the adult Drosophila midgut are regulated by growth factors produced from the surrounding niche cells including enterocytes and visceral muscle. The role of the other major cell type, the secretory enteroendocrine cells, in regulating intestinal stem cells remains unclear. We show here that newly eclosed scute loss-of-function mutant flies are completely devoid of enter...
متن کاملIntestinal Stem Cell Pool Regulation in Drosophila
Intestinal epithelial renewal is mediated by intestinal stem cells (ISCs) that exist in a state of neutral drift, wherein individual ISC lineages are regularly lost and born but ISC numbers remain constant. To test whether an active mechanism maintains stem cell pools in the Drosophila midgut, we performed partial ISC depletion. In contrast to the mouse intestine, Drosophila ISCs failed to repo...
متن کاملGastrointestinal stem cells. II. Intestinal stem cells.
Current views of the identity, distribution, and regulation of small intestinal epithelial stem cells and their immediate progeny are discussed. Recent works implicating Wnt signaling in stem and progenitor proliferation, the involvement of Notch signaling in epithelial lineage specification, and the role of hedgehog and bone morphogenetic protein families in crypt formation are integrated. We ...
متن کاملPutative intestinal stem cells
A heterogeneous set of intestinal stem cells markers has been described in intestinal glands but the ultrastructural identity of intestinal stem cells remains unknown. By using electron microscopy, this study demonstrated the presence of cells with stem morphology in the intestinal glands of mice of different ages. These putative intestinal stem cells have large, euchromatic, irregular shaped n...
متن کاملIntestinal inflammation and stem cell homeostasis in aging Drosophila melanogaster
As a barrier epithelium, the intestinal epithelium has to coordinate physiological functions like digestion and nutrient resorption with the control of commensal bacteria and the prevention of pathogenic infections. It can therefore mount powerful innate immune and inflammatory responses, while, at the same time, maintaining tissue homeostasis through regenerative processes. How these different...
