Nov 27, · Most epithelia are turned over throughout adult life as cells are lost from the surface and replaced by the proliferation of stem cells. Precise regulation of stem cells by signals from the local microenvironment or niche is important to maintain epithelial rucks.xyz by: Oct 01, · The adult gut and its cell types: genetic and anatomical compartmentalization. As shown in Figure 2C, the “ground plan” of the adult Drosophila gut consists of a tube lined by an epithelial monolayer consisting of four cell types: intestinal stem cells (ISCs), absorptive ECs, secretory EE cells, and enteroblasts (EBs): a postmitotic, immature cell type which will differentiate as an EC (or.
Apr 24, · Singh SR, Zeng X, Zheng Z, Hou SX () The adult Drosophila gastric and stomach organs are maintained by a multipotent stem cell pool at the foregut/midgut junction in the cardia (proventriculus). Cell Cycle 10 (7)– Google Scholar Cited by: 9. Five types of region and organ-specific multipotent adult stem cells have been identified in the Drosophila digestive system: intestinal stem cells (ISCs) in the posterior midgut; Adult stem cells maintain tissue homeostasis by continuously replenishing damaged, aged and dead cells in Cited by: 9.
Nov 01, · Like most animals, the intestine of the fruit fly Drosophila is a self-renewing tissue in which a population of stem cells generates new differentiated cell types to replace those that are damaged and lost during normal life (Micchelli and Perrimon ; Ohlstein and Spradling ; Jiang et al. ; Lemaitre and Miguel-Aliaga ).The intestinal stem cells (ISCs) reside in the basal region. Nov 15, · The precursors for intestinal stem cells (ISCs), called adult midgut progenitors (AMPs), first appear in the embryonic Drosophila midgut epithelium amongst a small number of diploid cells that are set aside to generate the future adult midgut epithelium during rucks.xyz by:
