ABSTRACT
Organoid is a newly developed cellular there-dimensional culture system in recent years. Organoids have a three-dimensional structure, which is similar to that of the real organs. Together with the characteristics of self-renewal and reproduction of tissue origin, organoids can better simulate the function of real organs. Organoids provide a new platform for the study of organogenesis, regeneration, disease pathogenesis, and drug screening. The digestive system is an essential part of the human body and performs important functions. To date, organoid models of various digestive organs have been successfully established. This review summarizes the latest research progress of organoids of taste buds, esophagi, stomachs, livers and intestines, and prospects future application of organoids.
