Abstract: This disclosure describes hardware for microfluidic chips and an associated support module for facilitating operation of one or more microfluidic chips. The microfluidic chips described herein are designed for supporting multiple different tissue types, including kidney tissue, liver tissue, adipose cells, and so forth. Chip geometry facilities fluid flow through one or more channels of the chip with a particular flow rate. For example, shear forces are reduced where needed to ensure proper flow rate of fluid in the channels. The chamber geometry and the geometry of the channels ensures that a desired amount of oxygen is delivered to sample cells or tissues in a controlled manner.

Abstract: Microphysiological platforms are configured for measuring kinetic rates relating to drug absorption. These kinetic rates include GI region-specific kinetic rates of drug absorption. The kinetic rates include bioavailability of the drug over time in various tissues. The kinetic rates include drug permeability in various tissues. The kinetic rates include measurements of microbial transformations that occur. The kinetic rates include measured effects of gastric emptying and transit times. The kinetic rates include measurements of fasting and fed states for various tissues.

Abstract: A microfluidic chip is configured to determine DILI parameters. The microfluidic chip includes a cell chamber hosting a tissue culture comprising liver tissue; a reoxygenation chamber configured to add oxygen to a fluid media; a fluid loop configured to recirculate the fluid media through the cell chamber and the reoxygenation chamber and supply oxygenated fluid media to the tissue culture; and an oxygen sensor configured to measure an oxygen concentration within the fluid media. The microfluidic chip includes a controller configured to perform operations including recirculating the fluid media in the fluid loop, the fluid media comprising a drug dose; obtaining measurements of the oxygen concentration at a sequence of time points during recirculating; and determining, based on the measured oxygen concentration, at least one physiologic parameter value of the tissue culture that describes a clinical test metric describing a damage level to the tissue culture.

Abstract: A microphysiological system (MPS) includes at least one first inlet for receiving a fluid medium. The MPS includes a brain module comprising brain tissue. The MPS includes a blood-brain-barrier (BBB) module comprising BBB tissue, the BBB module configured to receive the fluid medium. The MPS includes a crosstalk channel between the brain module and the BBB module, the crosstalk channel configured to promote a bidirectional crosstalk between the brain tissue and the BBB tissue in response to receiving the fluid medium at the BBB module. The MPS is configured for treating the brain tissue and the BBB tissue with a drug or a combination of drugs to determine a phenotypic effect and a transcriptomic effect of the drug. A drug perturbation is related to the phenotypic effect and the transcriptomic effect based on kinetic optimization.
