Advances in the application of co-culture strategies in organoids

Abstract

As a good in vitro research model, organoids are more and more widely used in the biomedical field. By developing self-assembled 3D structures using various tissue culture techniques, organoids can rebuild the high complexity of cells in the inherent structure of the organ, and are therefore unanimously used to study mechanisms regulating body development and disease, high-throughput drug screening, and personalized treatment and so on. To better recapitulate cell-to-cell interactions within the microenvironment, co-culture strategies have been extended to more cell types, and their rapid development offers broader prospects for organoids and paves the way for the treatment of human diseases and regenerative medicine. This review discussed the role of co-culture strategies in organoid generation, and focused on the application of various cellular components and microorganisms in organoid construction, thereby providing reference and help for scholars to construct and develop organoids with a higher degree of in vivo simulation.
