GL261 Cells

The GL261 cell line is a murine glioma model derived from C57BL/6 mice. This cell line is widely used in neuro-oncology research due to its ability to closely mimic the aggressive and invasive characteristics of human glioblastoma multiforme (GBM). GL261 cells grow as adherent cultures and form tumors when injected intracranially into syngeneic hosts, making them an ideal model for studying glioma progression, tumor microenvironment interactions, and therapeutic responses in an immunocompetent setting.
GL261 cells are known for their high proliferative capacity and expression of various glioma-associated markers, such as glial fibrillary acidic protein (GFAP) and S100. They exhibit mutations in key oncogenes and tumor suppressor genes, including p53 and PTEN, which are commonly altered in human GBM. This genetic profile, along with their robust in vivo tumorigenicity, has made GL261 a valuable tool for preclinical evaluation of anti-glioma therapies, including chemotherapy, radiotherapy, and immunotherapy approaches. Researchers also utilize GL261 cells to investigate the mechanisms of glioma invasion and resistance to treatment, contributing to the development of more effective clinical strategies.
