Preparation of Human Primary Colon Tissue-Derived Organoid Using Air Liquid Interface Culture.

Preparation of Human Primary Colon Tissue-Derived Organoid Using Air Liquid Interface Culture. Curr Protoc Toxicol. 2018 Feb 21;75:22.6.1-22.6.7 Authors: Usui T, Sakurai M, Umata K, Yamawaki H, Ohama T, Sato K Abstract In vitro analysis of intestinal epithelium has been hindered by a lack of suitable culture systems useful for gastrointestinal research. To overcome the problem, an air liquid interface (ALI) method using a collagen gel was established to culture three-dimensional primary cells containing both primary epithelial and mesenchymal components from mouse gastrointestinal tissues. ALI organoids accurately recapitulate organ structures, multilineage differentiation, and physiology. Since ALI organoids from human tissues have not been produced, we modified the previous protocol for mouse ALI organoid culture to establish the culture system of ALI organoids from normal and tumor colorectal tissues of human patients. The current unit presents a protocol for preparation of the ALI organoid culture from normal and tumor colorectal tissues of human patients. ALI organoid culture from human tissues might be useful for examining not only resistance to chemotherapy in a tumor microenvironment but also toxic effects on organoids. © 2018 by John Wiley & Sons, Inc.
