Abstract

Aim: To construct Luc-GFP-labeled human hepatocellular carcinoma (HCC) cell line with high metastatic potential. And to establish a spontaneous metastasis and conveniently monitored orthotopic model of hepatocellular carcinoma in nude mice. Methods: HCCLM3-Luc-GFP cell line stably expressing luciferase (Luc) and green fluorescent protein (GFP) was constructed by lentivirus transfection. The orthotopic xenograft model was established though cell suspension injection method and tumor fragment implanted method. The growth and metastasis of the tumors were observed by in vivo imaging and pathology. Results: HCCLM3-Luc-GFP, a highly metastatic HCC cell line with GFP expression and Luc activity, was obtained. The tumorigenic rates both of two approaches were 100%, but the lung metastatic rate was higher the former than the latter. Conclusion: The orthotopic model of highly metastatic and Luc-GFP-labeled HCC in nude mice was successfully established by above approaches , called as cell suspension injection method and tumor fragment implanted method, respectively. This study provides a new and effective means to monitor the growth of tumors in vivo and to evaluate the efficacy of anti-metastatic drugs against HCC.
