Microphysiological Systems

ABNEL has developed a laser cut and assemble microphysiological system (MPS), or organ-on-chip device, of the gut and the heart 1,2. MPSs allow for physiologically relevant modeling of organ systems and diseases with limited confounding factors present. This methodology is a more cost effective and manufacturable option compared to the current standard of PDMS soft lithography.

Ongoing research aims to develop an MPS of gut and enteric nervous system (ENS) physiology to further study the gut-brain connection. ABNEL also aims to develop MPSs of various neural disorders that have an expected connection to the gut including Parkinson’s, visceral pain, depression, and anxiety. The study of parasympathetic and sympathetic innervation in cardiac tissue is also being explored through the use of our cut and assemble MPSs. Electrophysiological techniques, such as transepithelial electrical resistance (TEER) and microelectrode arrays (MEA), are frequently utilized to study endothelial barrier function and neuronal action potentials, respectively.
