Fig 1. Schematic illustration of the platform. (A) The schematic of chip and cell culture. The chips are transferred onto a rocker placed in a cell culture incubator 24 hours after cell seeding.(B) 3D sectional view of the chip. The central hole displays the cell culture in the upper layer and the fluid flow in the interconnected lower layer. (C) Computational simulations reveal the magnitude of fluid shear stress above the membrane.
