mScarlet/LUC Reporter Cell Line - A-204

A-204 is a human rhabdomyosarcoma cell line originally established from a soft tissue tumor and is widely used as an experimental model for studying sarcoma biology, tumor progression, and therapeutic response. The cell line exhibits mesenchymal characteristics and has been employed extensively in investigations of cell proliferation, migration, invasion, and oncogenic signaling pathways associated with aggressive soft tissue malignancies. Due to its robust tumorigenic potential and reproducible growth characteristics, A-204 serves as a valuable platform for evaluating novel anti-cancer agents and elucidating mechanisms of sarcoma development. The mScarlet/LUC Reporter Cell Line - A-204 is generated through stable introduction of the red fluorescent protein mScarlet and firefly luciferase (LUC) reporter genes into parental A-204 cells. This dual-reporter system enables highly sensitive fluorescence imaging and quantitative bioluminescence detection while preserving the biological properties and tumor-forming capacity of the original cell line.

The A-204-mScarlet/LUC reporter cell line is broadly utilized in preclinical oncology research for monitoring tumor growth, metastatic dissemination, and treatment response in both in vitro and in vivo settings. Luciferase expression enables non-invasive, longitudinal assessment of tumor burden through bioluminescence imaging, allowing dynamic evaluation of disease progression and therapeutic efficacy in xenograft models. Simultaneously, mScarlet expression provides bright red fluorescence with excellent photostability, facilitating visualization of cellular morphology, migration, invasion, and tissue localization at high resolution. This model is particularly useful for screening anti-sarcoma compounds, assessing targeted therapies, and investigating mechanisms of drug resistance. In addition, the dual-reporter platform supports studies of tumor–microenvironment interactions, metastatic colonization, and signaling pathways involved in sarcoma progression. With stable reporter expression and robust imaging performance, the A-204-mScarlet/LUC cell line provides a reliable and reproducible tool for translational sarcoma research and preclinical therapeutic development.
