Here, we present several simple methods for evaluating viability and death in 3D cancer cell spheroids, which mimic the physico-chemical gradients of in vivo tumors much better than the 2D culture. The spheroid model, therefore, allows evaluation of the cancer drug efficacy with improved translation to in vivo conditions.

Understanding the malignant behavior of cancer requires creating accurate models of how tumor cells interact with components of the tumor microenvironment, such as macrophages. Here we describe two methods to study glioblastoma cell interaction with tumor associated macrophages and microglia where the effect on glioblastoma invasion is assessed.

GL261 glioma cells provide a useful immunocompetent animal model of glioblastoma. The goals of this protocol are to demonstrate proper techniques for monitoring intracranial tumor growth using in vivo bioluminescence imaging, and to verify the utility of luciferase-modified GL261 cells for studying tumor immunology and immunotherapeutic approaches for treating glioblastoma.

In this video, glioblastoma and microglia cells are mixed with a polymer matrix solution and transferred to a porous chamber insert where a gel forms, embedding the cells. Microglia stimulate the migration of glioblastoma cells through the porous insert, mimicking tumor cell invasion into surrounding tissue, Cells are then fixed and prepared for further analysis.
FAQs
When GL261 cells are implanted in immunocompetent mice, the resulting tumors develop while the host immune system remains active. This allows researchers to examine interactions between glioma cells and immune components within the tumor environment, rather than studying cancer cells in isolation. The model therefore supports investigation of immune responses and immunotherapy-related mechanisms in a living system.
Compatibility with C57BL/6 mice enables GL261 cells to be studied in syngeneic models, meaning the tumor and host share a compatible genetic background. This arrangement permits intracranial tumor formation in immunocompetent animals without removing the immune context. As a result, researchers can evaluate glioma biology and treatment responses under conditions that preserve cancer–host interactions.
GL261 tumors provide a platform for examining tumor growth, invasion, and the glioma microenvironment. Studying these processes together helps researchers assess how tumor behavior relates to its surrounding biological context. The model can also be used to connect these features with responses to experimental treatments, supporting broader analysis of glioblastoma-related cancer biology.
Researchers can implant GL261 cells intracranially in compatible immunocompetent mice, where they form tumors for subsequent study. This approach creates an in vivo setting for monitoring tumor-related biology and treatment responses rather than relying only on laboratory cell systems. The resulting model is particularly relevant when tumor location and immune interactions are important experimental considerations.
The model is useful for testing potential responses to radiation, chemotherapy, and immunotherapy in an immunocompetent glioma setting. Researchers can compare how tumors respond while retaining interactions between malignant cells and the host immune system. These experiments provide preclinical evidence that may help prioritize mechanisms or treatment strategies for further investigation before clinical research.
GL261 tumors do not reproduce every feature of human glioblastoma, so findings require careful interpretation when considering human disease. Their value lies in providing a practical, controlled system for investigating mechanisms and evaluating candidate treatments, not in serving as a complete replacement for clinical research. Results should therefore be viewed as preclinical evidence within the model’s scope.
