GFP/Luc Reporter Cell Line - HGC27

The HGC-27 cell line is a highly aggressive human gastric carcinoma model, originally established in 1976 from the metastatic lymph node of a patient suffering from undifferentiated stomach cancer. Cultured as an adherent epithelial monolayer, this line is characterized by its rapid proliferation and highly invasive properties, making it a classic representation of advanced, poorly differentiated gastric malignancies. The GFP/Luc Reporter Cell Line - HGC27 represents a sophisticated dual-labeled derivative of this foundational gastrointestinal oncology model. Through stable lentiviral transduction, these cells are engineered to constitutively co-express both green fluorescent protein (GFP) and the firefly luciferase enzyme. This dual genetic integration ensures that the cells simultaneously emit a robust bioluminescent signal upon exposure to the substrate D-luciferin and display bright green fluorescence under appropriate light excitation. Crucially, this targeted modification transforms the standard line into a highly versatile, dual-modality tracking tool while strictly preserving its original aggressive malignant phenotype, cellular morphology, and baseline metastatic behavior.

Leveraging its accurate representation of advanced gastric cancer, this dual-reporter cell line is an invaluable resource for pre-clinical oncology research and targeted drug development. In vivo, the constitutive bioluminescence enables the establishment of highly reliable orthotopic stomach models and peritoneal dissemination xenografts. By utilizing non-invasive bioluminescence imaging (BLI), researchers can continuously monitor localized primary tumor growth, dynamically track the spatiotemporal spread of metastases throughout the peritoneal cavity, and evaluate the efficacy of experimental therapeutics in living animals over time without requiring multiple endpoint sacrifices. Concurrently, the robust GFP expression facilitates precise ex vivo histological analysis, enabling the high-resolution spatial tracking of tumor margins, local tissue invasion, and micrometastases. In vitro, the dual optical readouts streamline high-throughput cell viability and cytotoxicity screening. Scientists rely on the green fluorescence for live-cell microscopy and flow cytometry, while leveraging the quantifiable bioluminescent signal to rapidly assess the direct cytotoxic impact of novel chemotherapeutics, targeted molecular inhibitors, and emerging immunotherapies directed against aggressive gastrointestinal malignancies.
