Liver Cell Culture System (IMAGE) Princeton University Caption Long-term co-infection of liver cells (hepatocytes) with HBV and HDV can be established in a highly scalable cell culture system. Image shown is of the cell culture 28 days after HBV/HDV co-infection, with hepatocyte nuclei in blue, a Hepatitis B viral protein in red, and HDV genomic RNA in green.
