U-87 MG-Luc Cells

U-87 MG-Luc cells are a bioluminescent derivative of the human U-87 MG glioblastoma cell line that have been genetically modified to stably express the firefly luciferase reporter gene. Upon exposure to luciferin substrate, these cells generate a luminescent signal proportional to viable cell number, enabling sensitive and quantitative monitoring of tumor growth, proliferation, and therapeutic response. U-87 MG-Luc cells retain many of the morphological and biological properties of the parental glioblastoma model, including adherent growth, rapid proliferation, and expression of markers commonly associated with astrocytic tumor cells.

The luciferase reporter system makes U-87 MG-Luc cells particularly valuable for orthotopic and subcutaneous xenograft studies in immunocompromised animal models. Bioluminescence imaging enables non-invasive longitudinal assessment of intracranial tumor establishment, invasion, recurrence, and response to experimental therapies, reducing the need for invasive procedures or large animal cohorts. These cells are widely used in preclinical neuro-oncology research for evaluating chemotherapeutics, targeted inhibitors, immunotherapies, radiation response, nanoparticle-based drug delivery systems, and gene therapy approaches. In vitro, U-87 MG-Luc cells are also suitable for high-throughput viability assays, migration and invasion studies, and real-time analysis of glioblastoma cell dynamics.

Like the parental U-87 MG line, U-87 MG-Luc cells exhibit characteristics associated with high-grade glioma biology, including altered signaling pathways involved in proliferation, apoptosis resistance, angiogenesis, and metabolic adaptation. Researchers should note that different repositories and laboratories may use independently generated luciferase-expressing variants with differences in vector integration sites, promoter systems, reporter intensity, and selection markers. Authentication and validation of luciferase stability, growth behavior, and molecular characteristics are therefore recommended prior to experimental use, particularly in studies involving long-term in vivo imaging or therapeutic screening.
