The SMMC-7721 cell line is a human hepatocellular carcinoma cell line that was originally derived from a liver biopsy of a 56-year-old male patient with hepatocellular carcinoma. The SMMC-7721 cell line is commonly used in cancer research to study hepatocellular carcinoma biology and to evaluate potential therapies for this disease.

The SMMC-7721 cell line is characterized by its high tumorigenicity, rapid growth rate, and invasive behavior, which closely resemble the features of human hepatocellular carcinoma. The SMMC-7721 cell line is commonly used in preclinical studies to investigate the mechanisms of hepatocarcinogenesis, identify potential therapeutic targets, and evaluate the efficacy and toxicity of various treatment modalities, such as chemotherapy, immunotherapy, and gene therapy.

The SMMC-7721 cell line has been extensively characterized, and its genome has been sequenced, making it a valuable tool for molecular and genetic studies of hepatocellular carcinoma. Additionally, the SMMC-7721 cell line has been used in studies exploring the role of the tumor microenvironment in cancer progression and the response to therapy.

To maintain the SMMC-7721 cell line in culture, suitable culture medium is required, and the cells need to be maintained at appropriate temperature and humidity conditions. Regular monitoring of cell confluence and viability is also essential.

Overall, the SMMC-7721 cell line is a valuable resource for cancer research, offering a powerful model system for investigating the biology of hepatocellular carcinoma and developing new therapies for this disease.
