Abstract In experimental neuro-oncology there remains a need for animal models that can be used to assess the efficacy of new and innovative treatment methodologies for glioblastoma multiforme (GBM). Rat models have remained the mainstay of neuro-oncology research for over 30 years; however, despite extensive experimentation, there is no one rat model that truly reflects the features of human tumours. We have developed a novel rat brain tumour model that closely resembles human GBM in biological behaviour and that utilizes bioluminescence imaging (BLI) to follow day-to-day in vivo progress of the tumour. F98 glioma cells were transfected with the firefly luciferase gene and injected orthotopically into the brains of 24 rats. Weekly BLI after subcutaneous injection of luciferin allowed for in vivo monitoring of the progress of the brain tumours. Euthanasia and histological analysis of the rodent brains at varying stages post-implantation, allowed for statistically significant correlation between tumour size and luminescence (p=0.002). The utility of this model is readily apparent, allowing us a way of examining the effects of new and novel therapeutics in these rats.
