Table 1.
Systems | Advantages | Limitations |
---|---|---|
Human hepatoma cell lines (HepG2, Huh7) | • Readily available • Robust in supporting steps in replication after transcription |
• Fail to support infection • Oncogenic transformation: only partially mimic normal hepatocytes |
HepaRG | • Support infection • Mimic normal hepatocytes better than other hepatoma cell lines |
• Low efficiency of infection • Complicated conditions for differentiation |
HepG2-NTCP | • Readily available | • Oncogenic transformation: only partially mimic normal hepatocytes |
Primary human hepatocytes | • Support HBV infection • Mimic normal hepatocytes the best • Support complete HBV life cycle |
• Low efficiency of infection • Limited in supply • High cost • Donor variability |
iHep cells | • Unlimited in supply • Support complete HBV life cycle • Mimic normal hepatocytes better than hepatoma cell lines |
• Complicated conditions for differentiation • Induced hepatocytes may not fully mimic mature hepatocytes |
