Lgr5+ Gastric Stem Cells Divide Symmetrically to Effect Epithelial Homeostasis in the Pylorus
1 Oct 2013
Abstract excerpt
The pyloric epithelium continuously self-renews throughout life, driven by limited reservoirs of resident Lgr5+ adult stem cells. Here, we characterize the population dynamics of these stem cells during epithelial homeostasis. Using a clonal fate-mapping strategy, we demonstrate that multiple Lgr5+ cells routinely contribute to epithelial renewal in the pyloric gland and, similar to what was previously observed...
