Figure 3From: Infection of hepatitis B virus in extrahepatic endothelial tissues mediated by endothelial progenitor cellsExpression of HBsAg and HBcAg antigens in EPCs. EPCs (A, B, D, E, G, and H) and HUVECs (C, F, and I) were co-cultured with HBV (A-C, and G-I) for 4 days, washed and maintained for another 3 days or without virus (D-F) for 7 days. The cells were either immunostained with anti-HBcAg antibody (A and C, × 200; and B, × 600), or analyzed by flow cytometry with anti-HBsAg (D and G) and anti-HBcAg antibodies (E, F, H and I).Back to article page
