Problems solved by technology

[0005] However, primary liver cancer has great heterogeneity, and different liver cancer cell lines have different tumor biological characteristics. Higher and higher
Moreover, there is still a lack of experimental materials in line with clinical tumor biological characteristics for liver cancer drug screening and evaluation.

Embodiment 1

[0021] Embodiment 1HCC-DJ711 cell preparation

[0022] Primary cell culture: fresh clinical liver cancer resection specimens obtained from Run Run Shaw Hospital Affiliated to Zhejiang University School of Medicine (patient, male, 59 years old, hepatocellular carcinoma of the right liver, poorly differentiated, tumor size 4×3cm, liver tissue Inner multifocal growth, with intravascular tumor thrombus formation, focal involvement of fat tissue outside the liver capsule, nodular cirrhosis) Immediately separate fresh liver cancer specimens. In a biological safety cabinet, after rinsing with fresh PBS, add a small amount of fresh 2g / L collagenase-4 solution (containing 500U / ml penicillin, 500μg / ml streptomycin sulfate, 1.25μg / ml amphotericin B) to remove blood Use sterilized scissors to chop as much as possible, transfer to a 15ml centrifuge tube after chopping, and add 10ml fresh collagenase-4 solution above, mix well, and store at 37°C, 5% CO 2 Incubate for 60 minutes. Add RPMI ...

Embodiment 2

[0025] Embodiment 2 Biology and application of human liver cancer cells

[0026] The invention adopts DMEM / F12 culture solution containing fetal bovine serum to cultivate HCC-DJ711 cells, so as to make long-term growth and stable passage in vitro. Observed under the microscope, HCC-DJ711 cells have typical epithelial cell-like morphology, growth inhibition due to loss of contact, and malignant growth. A certain amount of HCC-DJ711 cells can form tumors under the skin of nude mice, indicating that the cells have tumorigenic properties. The cell can be used for the research on the mechanism of the occurrence and development of liver cancer. At the same time, it can be used to screen and evaluate anti-liver cancer drugs, discover drugs sensitive to liver cancer, guide clinical medication, and open up new ideas for liver cancer treatment. details as follows:

Abstract

The invention discloses a human hepatocellular carcinoma cell strain as well as a construction method and application thereof. The hepatoma cell strain is named as a human hepatocellular carcinoma cell strain HCC-DJ711, and is preserved in China Center for Type Culture Collection on April 15, 2018, and the preservation number is CCTCC NO:C201889. According to the invention, cells are extracted andseparated from a clinical liver cancer specimen, and the liver cancer cell strain has good animal tumorigenesis characteristics, can be used as a cell model for researching liver cancer occurrence and development mechanisms, and can be used for screening and evaluating liver cancer drugs and guiding clinical medication.

Description

technical field [0001] The invention relates to the fields of biology and oncology, and relates to a human liver cancer cell line and its construction method and application. Background technique [0002] Liver cancer is the most common liver tumor. There are about 1 million new cases of liver cancer every year in the world. It ranks sixth in the incidence of cancer worldwide and is the third leading cause of cancer-related death. As a big country with hepatitis B, primary liver cancer is the most common tumor in my country. The incidence and mortality of liver cancer are among the highest in the world, and new cases and deaths each year account for more than 50% of the national cases. At present, the incidence of liver cancer in my country is high, the mortality rate is high, and the cure rate is low. It often progresses rapidly. Most patients have entered the middle and late stages when they are diagnosed. If intrahepatic metastasis, vascular invasion or distant metastasis...
