Abstract

The present invention relates to the field of microbial animal cells, and specifically a hepatoma cell line STL-C1 derived from human hepatoma para-carcinoma tissue. The cell line has a preservation number CCTCC No:C201630. The present invention also provides an establishment method and application of the cell line. The established hepatoma cell line STL-C1 is derived from human hepatocellular hepatoma para-carcinoma tissue, and can be cultured in vitro for a long term and has stable passage; and in vivo experiments show that the cell line still has good tumorigenic property, and is completely different from the currently existing established common hepatoma cell lines and even from the hepatoma cancer embolus cell line. The hepatoma cell line STL-C1 has important usage and reference value to the study of the formation of satellite lesions, and biological behaviors suahc as recurrence and transfer of primary hepatic carcinoma, is a novel cell model for basic and clinical research of hepatoma, and has broad application prospects.

Description

technical field [0001] The present invention relates to the field of microbial animal cells, specifically, a liver cancer cell line STL-C1 isolated and established from human hepatocellular carcinoma paracancerous tissue samples, its construction method and application. Background technique [0002] Primary liver cancer (Hepatocellular carcinoma, HCC) is one of the most common malignant tumors in my country, ranking second only to lung cancer in tumor-related deaths, and the prognosis of patients is extremely poor. Although surgical resection of the primary lesion is still the most effective treatment for liver cancer at present, most of the patients are in the middle and advanced stage and have metastases in and out of the liver when they are diagnosed. Therefore, the surgical resection rate is low, the recurrence rate is high, and the clinical effect is still not satisfactory. Therefore, it is particularly urgent and important to study the molecular mechanism of the occurr...
