Characterization of platelet-derived growth factor receptor-β-positive (PDGFRβ+) pericytes from macaque lungs. A: phase contrast microscopy image of cultured macaque lung pericytes with thin long processes (arrows). B: flow cytometry for PDGFRβ positivity. C: in situ hybridization (RNAscope) for PDGFRβ mRNA (green dots). Representative image of 3 isolates. D: Western blotting of pericytes from simian immunodeficiency (SIV) virus-negative (SIV−; n = 2) and SIV-positive (SIV+; n = 3) macaques for CD4, CXCR4, and CCR5.
