Colonic subepithelial myofibroblasts in mucosal inflammation and repair: contribution of bone marrow-derived stem cells to the gut regenerative response

Abstract

mesenchymal cells that exhibit the ultrastructural features of both fibroblasts and smooth muscle cells, and they are characterized by positive immunoreactivity for a-smooth muscle actin (a-SMA) and vimentin, but negative immunoreactivity for desmin (Figs. 1A and B).4–6,7 SEMFs are distinguished from smooth muscle cells, which express a-SMA but are negative… (More)
