Generation and banking of patient-derived glioblastoma organoid and its application in cancer neuroscience.

Glioblastoma (GBM) is the most common and deadly tumor in the central nervous system. Although much has been done to optimize treatment options for GBM, the clinical prognosis is still very poor. The recent development of organoid models are emerging as cutting-edge tools in GBM research. However, the established and applications of organoid in cancer neuroscience are still elusive. In this study, we successfully established patient-derived GBM organoids (GBOs) with conserved pathological properties of parental GBM. Moreover, GBO-neuron co-culture system was also investigated and interactions between GFP labeled neurons and mCherry labeled GBOs have been observed. We further used an in-situ stereotaxic instrument to implant GBO into the brains of nude mice and established intracranial orthotopic GBM models based on these GBOs. Thus, we proposed a system to generate and bank patient-derived GBOs and verified its application in cancer neuroscience, which might be an important way to illustrate the mechanism of GBM.
