Pericytes, vSMCs, and many other perivascular cell types[clarification needed] express very similar markers such as Platelet Derived Growth Factor Receptor Beta (PDGFR-B), aminopeptidase-N (CD13), chondroitin sulfate proteoglycan 4 (Ng2), or desmin, which makes their identification difficult and requires a combination of markers: for example vSMCs but not pericytes express alpha-smooth muscle actin (ACTA2). Nowadays, distinctively characterizing these cells requires a combination of markers, cellular location and morphology.
