METHOD FOR PRODUCING MULTI-TISSUE LUNG ORGANOID SURROUNDED BY FIBROBLASTS, AND USE THEREOF

Abstract

The present invention relates to a method for producing a multi-tissue lung organoid structurally surrounded by fibroblasts, and a use thereof, and provides a three-dimensional structure composed of a lung organoid and a fibroblast layer surrounding the outside thereof. The organoid according to the present invention can maintain a high level of structural stability and bio-fidelity by reproducing a cell arrangement and microenvironment similar to those of actual lung tissue. The multi-tissue organoid more precisely reproduces a microenvironment in which epithelial tissues and interstitial tissues are arranged in layers as in a living body, rather than adopting a simple cell mixing method, and thus can be used in various biomedical applications, such as regenerative medicine, research on lung disease conditions, and evaluation of responsiveness to anticancer drugs and anti-fibrotic drugs. In addition, the present invention has excellent expandability to organoid-on-chip technology or bio-artificial organ development, and thus can be expected to be used as a precision medicine and next-generation cell therapy platform.
