GFP/Luc Reporter Cell Line - 5637

5637 is a human urinary bladder carcinoma cell line established from a grade II transitional cell carcinoma of the bladder. It is one of the most extensively characterized bladder cancer cell lines and has been widely used in studies of urothelial tumor biology, oncogenic signaling, tumor progression, and therapeutic response. The 5637 cell line exhibits epithelial morphology and possesses molecular features representative of intermediate-grade urothelial carcinoma, making it a valuable model for investigating mechanisms of bladder cancer development and disease progression. The GFP/Luc Reporter Cell Line - 5637 is generated through stable transduction of green fluorescent protein (GFP) and firefly luciferase (Luc) reporter genes into parental 5637 cells. This dual-reporter system enables real-time fluorescence imaging and highly sensitive bioluminescence detection while maintaining the biological characteristics, proliferative capacity, and tumorigenic potential of the original cell line.

The 5637-GFP/Luc reporter cell line is widely utilized in bladder cancer research for both in vitro assays and in vivo tumor models. Luciferase expression enables non-invasive longitudinal monitoring of tumor growth, dissemination, and therapeutic response through bioluminescence imaging, providing a quantitative method for evaluating disease progression in xenograft studies. GFP expression facilitates direct visualization of cell morphology, migration, invasion, and tissue localization in cultured cells and harvested specimens. This model is particularly useful for screening anti-cancer compounds, assessing targeted therapies, and investigating mechanisms of drug sensitivity and resistance in urothelial carcinoma. In addition, the dual-reporter platform supports studies of tumor microenvironment interactions, epithelial–mesenchymal transition, cancer stem cell-associated properties, and signaling pathways involved in bladder tumor progression. Owing to its stable reporter expression and reproducible imaging performance, the 5637-GFP/Luc cell line provides a robust experimental tool for preclinical drug evaluation and translational research in bladder cancer.
