MAP2 and glioblastoma: Interestingly, while neuronal cells showing axonal structures (SMI312) and MAP2 expression were present in our model, they were spatially segregated from GFP+ cells and appeared less permissive to tumor cell invasion, a finding consistent with xenograft models in which glioblastoma cells predominantly invade astrocyte- and microglia-rich regions rather than neuronal areas.89
