MICROFLUIDIC DEVICE FOR FORMING THREE-DIMENSIONAL TISSUE BARRIER

Application US20260109925A1 Kind: A1 Apr 23, 2026

Inventors

Yong Tae KIM, Hoon Suk Rho

Abstract

The present invention relates to a microfluidic device for mimicking the structure and function of an in vivo tissue barrier. Specifically, the present invention relates to a microfluidic device which replaces an animal model by mimicking the structure and function of a 2D-3D connective tissue barrier, a 3D tissue barrier, and a 3D-3D tissue barrier, and thus may be used as a model for new drug development and toxicity assessment, a method for culturing cells in the microfluidic device, and a method for mimicking an organ or a tissue using the microfluidic device.
