Clinical Info

A marker of myeloid lineage
CD13 (cluster of differentiation 13) plays roles in peptide metabolism (brush border membranes of small intestine, renal proximal tubules, and placenta), cell growth and differentiation, and phagocytosis. CD13 is normally expressed on myeloid lineage cells, including granulocytes and monocytes. It is also expressed on non-hematolymphoid cells including endothelial cells and fibroblasts, and is present in a soluble form in plasma. This immunostain may be useful as a marker of myeloid lineage in acute leukemias.
