Embodiment 1

[0044] Example 1 is the preparation of the cell line hSS-005R of the present invention.

[0045] Primary culture method: Place fresh synovial sarcoma specimens resected during operation in DMEM high glucose + 10% FBS complete medium in a sterile state, and store them on ice. After rinsing with fresh PBS buffer (containing 1% double anti-penicillin, streptomycin), cut into thin slices, attach the cut tissue pieces to the bottom of the cell culture flask, add appropriate amount of DMEM high sugar +10 Complete culture with %FBS is based on 37°C cell culture incubator with 5% carbon dioxide and placed upright for 1 hour to make the tissue pieces stick firmly to the bottom of the bottle. The upright flask is then gently and slowly tipped over to submerge the adherent tissue pieces with complete medium. There is no need to change the medium, and the cells can usually be observed climbing out of the tissue block after 4-5 days. When the medium turns yellow, replace with a new mediu...

Embodiment 2

[0049] Example 2 is the biological characteristics and application of hSS-005R cells.

[0050] The invention adopts DMEM high-sugar culture medium to cultivate and purify hSS-005R cells, so that the hSS-005R cells can grow and pass stably in vitro for a long time. When the cells are passed on for more than 30 generations, the cell traits are gradually stabilized, and relevant biology, genetics, and tissue source identification are carried out until the 50th generation has the same stable traits. The hSS-005R cells can form tumors in nude mice and have tumorigenicity. The corresponding relationship between the hSS-005R cells and the clinical synovial sarcoma tumor specimens derived from them, and the parental tumors passaged in nude mice can provide a new test for studying the correlation between in vitro, in vivo and clinical anticancer drug sensitivity and drug resistance Material. details as follows:

Abstract

The invention provides a synovial sarcoma cell line hss-005R, which is preserved in the China Center for Type Culture Collection (CCTCC) with the preservation number of CCTCC NO. C201911. The invention further provides an offspring cell line of the synovial sarcoma cell line hss-005R. A new human synovial sarcoma cell line is established, which is stable in character and can be stably passed for multiple generations. Under the premise of retaining main clinical biological characteristics, the established human synovial sarcoma cell line has the characteristics of high tumor formation rate, short incubation period, good uniformity and the like, enriches a synovial sarcoma cell bank, and can successfully establish a synovial sarcoma animal model, wherein the established animal model can be used for fundamental research and drug screening, so as to provide powerful scientific research data for the research developed on the basis of Chinese population genetic background, and provide new test material for test on sensibility and tolerance of a clinical anti-cancer drug of a new drug preclinical study in vivo experiment.

Description

technical field [0001] The invention belongs to the field of tumor cell research, in particular to a synovial sarcoma cell line hSS-005R and its progeny cell line. Background technique [0002] Synovial sarcoma (synovial sarcoma) is a highly invasive and highly malignant tumor. Synovial sarcoma accounts for 5-10% of all soft tissue sarcomas, and accounts for 10-20% of soft tissue tumors in adolescents and young adults. Between 1983 and 2012, the incidence of synovial sarcoma continued to increase from 0.906% to 1.548%. Synovial sarcoma occurs in the extremities, accounting for about 70% of all synovial sarcoma cases. The most common metastatic sites of synovial sarcoma are the lungs, followed by lymph nodes and bone marrow. Synovial sarcoma was originally named for its microstructural similarity to the surrounding synovial tissue when it is found in tissues near joints. However, some studies in recent years have shown that synovial sarcoma can appear in tissues lacking sy...
