Core Tip

Core Tip: A new ampullary carcinoma cell line has been established, making up for the shortage of Chinese ampullary carcinoma cell lines. And this is the the first study to report a mixed-type ampullary carcinoma cell line. The cell line inoculated into BALB/c nude mice can quickly form xenograft tumors. It is an excellent model for studying the mechanisms of invasion, metastasis and other mechanisms of ampullary carcinoma. The cell line is sensitive to oxaliplatin and paclitaxel but is naturally resistant to gemcitabine and fluorouracil, which can be used for drug resistance mechanism research and new drug development.
