Schematic representations (top view) of three potentially applicable microfluidic setups to study fluid transport in the human brain in vitro: a) Microfluidic platform comprised of two microchannels embedded in an astrocyte‐laden hydrogel to study glymphatic influx. b) Compartmentalized platform to investigate lymphatic clearance. c) Microfluidic device interconnecting vascular networks with a choroidal barrier to emulate the choroid plexus. Oscillatory flow patterns induce physiological barrier properties.
