The Wnt target gene Lgr5 marks stem cells in the small intestine, colon, and hair follicle. Here, we investigated Lgr5 expression in the stomach and assessed the stem cell potential of the Lgr5+ve cells by using in vivo lineage tracing.

2009). To determine whether Lgr5 expression is also modulated by Wnt signaling in the inner ear, we tested the effects of Wnt agonist and antagonist on cochlear explants. 2010-01-08 · The Wnt target gene Lgr5 marks stem cells in the small intestine, colon, and hair follicle. Here, we investigated Lgr5 expression in the stomach and assessed the stem cell potential of the Lgr5 +ve cells by using in vivo lineage tracing.

A three-dimensional culture system allows long-term clonal expansion of single … Lgr5 was originally discovered as a common Wnt target gene in adult intestinal crypts and colon cancer. It was subsequently identified as an exquisite marker of multiple Wnt-driven adult stem cell types. Lgr5 and its homologs, Lgr4 and Lgr6, constitute the receptors for R-spondins, potent Wnt signal enhancers and stem cell growth factors. The Wnt target gene Lgr5 has been recently identified as a novel stem cell marker of the intestinal epithelium and the hair follicle. In the intestine, Lgr5 is exclusively expressed in cycling crypt base columnar cells.

LGR5, an orphan receptor of the G protein-coupled receptor (GPCR) superfamily, is specifically 2018-01-09 · Background The WNT pathway regulates intestinal stem cells and is frequently disrupted in intestinal adenomas.

CSC populations have been identified on the basis of the markers Lgr5 [156, On the other hand, more differentiated cells showing an overactivation of Wnt såsom aldehyddehydrogenas ( ALDH1 ), ALCAM (CD166) och LGR5 [46–48] undertryckning av HOX-genuttryck observerades i iPSC: er, övergående WNT LGR5 is a member of the Wnt signaling pathway. Although its ligand remains elusive, it has been shown that costimulation with R-spondin 1 and Wnt-3a induce increased internalization of LGR5. LGR5 also cointernalizes with LRP6 and FZD5 via a clathrin -dependent pathway to form a ternary complex upon Wnt ligand binding. LGR5 is a new functional GSC marker and prognostic indicator that can promote EMT by activating the Wnt/β-catenin pathway and would thus be a novel therapeutic target for glioma. Lgr5 homologues are facultative Wnt receptor components that mediate Wnt signal enhancement by soluble R-spondin proteins. These results will guide future studies towards the application of R-spondins for regenerative purposes of tissues expressing Lgr5 homologues.
