Abstract
ABSTRACT
This article shows the contribution of colonic sub-epithelial microfibroblasts are the source of Wnt signaling in the colon. Wnt signaling is known to play an important role in the various stages of embryogenesis and carcinogenesis. Recent reports have implicated that Wnt proteins could act as growth factors, maintaining the stem cell phenotype and even controlling the symmetry of stem cell divisions. The Wnt family consists of 19 different genotypes in humans and the mouse. The source of Wnt signaling and its regulation is obscure.
