A brain cancer microtissue model for studying tumor cell and neural cell interactions

Key Discoveries

• Novel brain cancer co-culture model — The BCM model was developed by co-culturing rat cortical microtissues with rat glioma cell lines, enabling study of tumor-neural cell interactions that are difficult to model with existing in vitro approaches.
• Glioma behavior matches in vivo — Characterization showed that GBM cell motility, invasiveness, and interactions with neurons, astrocytes, and microglia in the BCM model are consistent with behavior observed in living organisms.
• Multi-cell type interactions captured — The platform successfully models complex interactions between tumor cells and normal central nervous system cells including neurons, astrocytes, and microglia.
• Enables high-throughput drug screening — The BCM model provides a platform for future therapeutic screening against glioblastoma and potentially other brain tumors and cancers that metastasize to the brain.
