Abstract

The invention provides an establishing method of a Chinese tongue squamous cancer cell line (CTSC-1), and provides a material base for researching the characteristics of tongue squamous cancer and therapeutics thereof. The establishing method comprises the steps of: carrying out primary culture on the tongue squamous cancer cells by adopting a tissue explants adherent method; subculturing when the cell density reaches about 80 percent; carrying out RT-PCR (Reverse Transcription-Polymerase Chain Reaction) detection on stably subcultured cells to indicate that the cells express tongue squamous cancer cell symbolic molecules CK 8, 18 and 19; and detecting adherent cells through a western blot test to express proteins of the tongue squamous cancer cell symbolic molecules CK 8 and 18, therefore, proving on a molecular level the successful establishment of the CTSC-1.

Description

technical field [0001] The present invention relates to the technical field of human tongue squamous cell carcinoma cells, in particular to a Chinese tongue squamous cell carcinoma cell line CTSC-1 and its establishment method. Background technique [0002] 1.1 Incidence and prognosis of tongue squamous cell carcinoma [0003] Tongue cancer is the most common oral squamous cell carcinoma, usually occurring in the anterior two-thirds of the tongue. Tongue cancer has a high incidence in Southeast Asia, with the highest incidence in India, with an annual incidence rate of 9.4 / 1 million. Studies in recent years have shown that the total incidence of tongue cancer worldwide is gradually increasing, and there is a trend of younger age. Due to the histological characteristics of the site where it occurs and the biological characteristics of tongue cancer, tongue cancer restricts tongue movement in patients, resulting in difficulties in swallowing, speaking, and eating. In additi...
