Abstract:
Objective To establish a rabbit VX2 liver tumor model by transplanting tumor tissue mass into the rabbit's liver,to analyze and observe the growing features of the liver tumor.Methods The tumor tissue mass(about 106-108 VX2 liver tumor cells)was inoculated into the left hepatic labe in 20 rabbits to establish rabbit VX-2 hepatic carcinoma model.The observation included the following two respects.(1)The tumor's volume at 7,10,14,17 and 21 days after the procedure was measured by ultrasonography and the growth rate of tumor was calculated.(2)The morphological feature of the tumor was inspected both macroscopically and microscopically.Results The growing pattern of the tumor was compatible with the exponential curve.Seventeen days after transplantation the increase rate of the tumor volume was much higher than that of the tumor diameter. Histopathologjcally,the growing pattern of the tumor took the form of infiltrative way,with its appearance being quite similar to the VX2 squamous cell carcinoma.Conclusion Transplantation of tumor tissue mass is the technique of first choice to establish the VX2 liver carcinoma model in rabbits.This experimental model is a very ideal animal form for both clinical and fundamental studies of liver carcinoma.
