Abstract
Systems and methods for measuring dynamic hydraulic conductivity and permeability associated with a cell layer are disclosed. Some systems include a microfluidic device, one or more working-fluid reservoirs, and one or more fluid-resistance element. The microfluidic device includes a first microchannel, a second microchannel, and a barrier therebetween. The barrier includes a cell layer adhered thereto. The working fluids are delivered to the microfluidic device. The fluid-resistance elements are coupled to one or more of the fluid paths and provide fluidic resistance to cause a pressure drop across the fluid-resistance elements. Mass transfer occurs between the first microchannel and the second microchannel, which is indicative of the hydraulic conductivity and/or dynamic permeability associated with the cells.
