Advancing organoid development with 3D bioprinting

Abstract

Organoidsprovidemorerealistic invitro modelsthatcloselymimictheircorresponding tissues or organs. Three-dimensional (3D) bioprinting allows for precise control over cell distribution, arrangement, and the regulation of cell behavior and interactions, offering flexibility and repeatability. By combining 3D bioprinting with organoid culture, optimal extracellular matrix conditions can be created, better replicating the complex interactions between cells and their environment. The integration of 3D bioprinting amplifies the scalability of organoids, facilitating the development of large-scale organ models that significantly enhance research capabilities. This review explores the crucial role of 3D bioprinting in organoid development, emphasizing its contributions to improving organoid structure and functionality. We discuss how this innovative approach supports the creation of well-defined physiological microenvironments, aids in the development of functional organoids, and enables high-throughput cultivation. Furthermore, we highlight the advantages of optimizing bioprinting strategies and bioinks to advance organoid applications. In addition, we examine the importance of refining 3D bioprinting devices to enhance organoid fabrication and application. Finally, we outline strategies for leveraging 3D bioprinting to further advance organoid research and its implications for regenerative medicine and disease modeling.
