Glioblastoma on a microfluidic chip: Generating pseudopalisades and enhancing aggressiveness through blood vessel obstruction events
Background: Glioblastoma (GBM) is one of the most lethal tumor types. Hypercellular regions,
named pseudopalisades, are characteristic in these tumors and have been hypothesized …
