Establishment and characterization of human colorectal cancer orthotopic implantation model in nude mice / 国际外科学杂志

ABSTRACT

Objective To establish and characterize human colorectal cancer orthotopic implantation model in nude mice.Methods Established the human colorectal cancer orthotopic implantation model by surgery,characterize its biological characteristics by immunohistochemistry.Results Human colorectal cancer orthotopic implantation model was established in nude mice successfully,the proliferating cell nuclear antigen and Survivin were overexpressed in the models which were simulated the characteristics of human colorectal cancer perfectly.Conclusion This human colorectal cancer orthotopic implantaion model will provide an excellent animal model for us to study the development and metastasis mechanism of human colorectal cancer.
