Rapid Induction of Orthotopic Hepatocellular Carcinoma in Mice by Fixed Puncture Point Injection Abstract Aim: Animal model is an indispensable tool in investigating the development, progression and treatment of human cancer including hepatocellular carcinoma (HCC). However, it is still challenging in establishing orthotopic HCC mouse models. Here, we presented a minimally invasive method with high tumor formation rate in mouse liver. Methods: Hep3B-luc and SNU-449-luc HCC cells mixed with Matrigel were injected into the liver of nude mice from different source at fixed injection site and depth, respectively. The mice were divided into 3 groups. At fifteen days post-injection, the bioluminescence signal of liver tumor was detected and tumors in injected mouse liver were harvested. Cons and pros were then compared between presented and common approaches. Results: We successfully developed an orthotopic transplantation tumor model in nude mice by directly injectin...
