Abstract

To study the feasibility of the establishment of the orthotopic transplantation tumor model of hepatocellular carcinoma in mice and its tumor biological characteristics. H22 cells of hepatocellular carcinoma were inoculated to form ectopic transplanted model in mice by subcutaneous injection. Then the subcutaneous tumors were implanted into the liver of mice, and the orthotopic transplantation tumor model of hepatocellular carcinoma was established. The successful rate of the orthotopic transplantation tumor model was 95.6% and the spontaneous metastatic rate was 81.8%, the rate of mass ascites was 40.9% and the natural extinctive rate was 0%. The natural survival time in the orthotopic transplantation tumor model was 28 days and the proliferation of tumor in transplanted model was accelerated after 2 weeks or so. The orthotopic transplantation tumor model in mice is an ideal model for studying the metastatic mechanism and screening anti-tumor drugs for liver cancer, just because of its high successful rate and high spontaneous metastatic rate with no natural extinction.
