Figure 4From: Infection of hepatitis B virus in extrahepatic endothelial tissues mediated by endothelial progenitor cellsTime dependent expression of HBV in EPCs. Detection of HBV DNA and HBV particles in EPCs (A and C) and HUVECs (B) by qRT-PCR analysis (A and B) and by transmission electron microscopy (C) at various times as indicated. The viral particles were calculated under transmission electron microscopy (× 20,000) from 5 different fields. D = Day.Back to article page
