CD31, also known as platelet endothelial cell adhesion molecule 1 (PECAM1), is a type I integral membrane glycoprotein and a member of the immunoglobulin superfamily of cell surface receptors. It is constitutively expressed on the surface of endothelial cells and is specifically concentrated at the junction between them. Therefore, CD31 antibodies are commonly used as endothelial markers to measure angiogenesis in association with tumor recurrence. It is also weakly expressed on many peripheral lymphoid cells and platelets. Other studies have also indicated that CD31 and CD34 can be used as markers for myeloid progenitor cells and recognize different subsets of myeloid leukemia infiltrates (granular sarcomas).
