CD73 (ecto-5′-nucleotidase) |
Mesenchymal stem cell marker,79 which also is expressed in T lymphocytes,80 marks cortical stroma but not medullary; in our hands not a reliable marker of kidney pericytes |
CD248 (endosialin) |
C-type lectin transmembrane receptor, also expressed on vascular smooth muscle cells, fibroblasts, myofibroblasts, and T cells2
|
α-SMA |
Intracellular protein linked to cell contractility expressed by smooth muscle cells and myofibroblasts, and not expressed by quiescent pericytes81
|
NG2 (chondroitin sulfate proteoglycan 4) |
Proteoglycan expressed by pericytes during early angiogenesis,1 vascular smooth muscle cells, adipocytes, and neuronal cells2,81
|
Desmin |
Type III intermediate filament, also expressed by mesangial cells, cardiomyocytes, and skeletal muscle cells2,82
|
p75 (low-affinity nerve growth factor receptor) |
Tumor necrosis factor–receptor superfamily member expressed on hepatic stellate cells and adult pericytes1,81
