CategoryInducing factorLatencyAdvantagesDisadvantages
XenograftEctopicCancer cell lineSeveral weeksFast and easy modelingLess clinical relevancy
OrthotopicEasy detection of tumorigenesisOnly reflect the characteristics of the selected cells
Carcinogen-inducedDEN5-10 moMore clinical relevancyLengthy time and high cost to model
Genetically engineeredHBV-derived12-24 moUncovering the molecular mechanisms of hepatocarcinogenesisDifficult to detect tumorigenesis
HCV-derived12-24 moClosely mimic the pathophysiological features of human HCC
Oncogene-derivedSeveral weeks
