Transformative potential of three-dimensional bioprinting technology for advanced organoid research

Abstract

Organoid research has emerged as a transformative field in biomedicine, focusing on the in vitro development of 3-dimensional (3D) structures that mimic human organs. Derived from various types of stem cells, organoids closely replicate human organ structures and functions, offering significant advantages over 2-dimensional cell cultures and animal models, particularly for drug development, tissue engineering, and precision medicine. Recent innovations, including the integration of biofabrication technologies, have significantly increased the structural complexity and maturity of organoids, expanding their biomedical applications. A critical factor in organoid culture is the utilization of the extracellular matrix (ECM), particularly decellularized ECM hydrogels. These hydrogels are instrumental in organoid growth and development, effectively simulating in vivo environments and supporting organoid functionality across various organ systems. The integration of 3D bioprinting technology into organoid research marks a transformative shift that has enabled the creation of intricate and customized structures. This review demonstrates that these technological innovations have not only revolutionized tissue engineering and regenerative medicine, but also hold immense potential for pharmacology, disease modeling, and personalized medical interventions. The synergistic integration of these technologies presents a promising future for medical research, paving the way for significant advancements in disease modeling, drug discovery, and the development of patient-specific treatments, and marking our entry into a new era of precision medicine and personalized healthcare solutions.
