  • Cell line of renal sarcomatoid carcinoma in persons of Han nationality and preparation method thereof
    Patent number: 9386762
    Abstract: Provided is a renal sarcomatoid cell line RCC09HYF, of which the deposit No. is CCTCC C201130, and the preparation method of the renal sarcomatoid cell line. The renal sarcomatoid cell line RCC09HYF can grow for a long period and be steadily passaged in vitro. By tumorigenic experiments using in-situ animal models in vitro it has been found that: the tumorigenesis is relatively fast inside animals and 3-4 weeks after tumor inoculation, the transplanted tumors fill the whole abdominal cavity, and dyscrasia appears in above 50% of nude mice; moreover, lung metastasis is present in a few individuals. The renal sarcomatoid cell line RCC09HYF can provide an effective and steady cell model for further study of the genesis and metastasis mechanism of renal sarcomatoid carcinoma in persons of Han nationality and for clinical prediction, diagnosis and treatment.
