Pericyte morphology. NG2 + pericytes are localized to the abluminal surface of adipose tissue capillaries (arrowhead) in mice that express red fluorescent protein (DsRed) under the control of the promoter of chondroitin sulfate proteoglycan 4 (encoding NG2). Pericyte cell bodies (asterisks) are prominently visible due to nuclear localization of DsRed.

We should note that these markers are also expressed by other cell types including perivascular fibroblasts, VSMCs and …
WebPericytes are a perivascular cell type that regulate angiogenic functions throughout the CNS, which involves the integrity of microvasculature and the blood-brain/spinal cord barrier (BBSB) through the lining of blood capillaries (Armulik et al., 2010, Bergers and Song, 2005 ).
