Abstract: Provided herein relates to systems and methods for producing and using a body having a central channel separated by one or more membranes. The membrane(s) are configured to divide the central channel into at least one mesochannel and at least one microchannel. The height of the mesochannel is substantially greater than the height of the microchannel. A gaseous fluid can be applied through the mesochannel while a liquid fluid flowing through the microchannel. The systems and methods described herein can be used for various applications, including, e.g., growth and differentiation of primary cells such as human lung cells, as well as any other cells requiring low shear and/also stratified structures, or simulation of a microenvironment in living tissues and/or organs (to model physiology or disease states, and/or to identify therapeutic agents and/or vaccines). The systems and methods can also permit co-culture with one or more different cell types.

Abstract: An organ-on-chip apparatus includes a first fluid channel, a second fluid channel, and an interface. Respective portions of the first fluid channel and the second fluid channel may extend parallel to and adjacent each other, and the interface may be disposed between the respective portions of the first fluid channel and the second fluid channel such that fluid exchange between the first fluid channel and the second fluid channel is via the interface. The first and second fluid channels may be defined in an extracellular matrix material.
