We have recently found abundant and selective expression of Adamdec1 in colonic mucosal PDGFRα⁺ cells. However, the cellular origin for this gene expression is controversial as it is also known to be expressed in intestinal macrophages. We found that Adamdec1 mRNAs were selectively expressed in colonic mucosal subepithelial PDGFRα⁺ cells. ADAMDEC1 protein was mainly released from PDGFRα⁺ cells and accumulated in the mucosal layer lamina propria space near the epithelial basement membrane. PDGFRα⁺ cells significantly overexpressed Adamdec1 mRNAs and protein in DSS-induced colitis mice.
