A microfluidic device is demonstrated to analyze glioblastoma migration along constraints with precisely designed geometries. This in-vitro model reveals physiologically relevant glioma invasion scenarios: full migration along constraints, suspended motion by extreme constriction, and limited migration associated with the ejection of plasma membrane particles due to the continuing extension.
