Bioprinted Organoids: An Innovative Engine in Biomedicine

Abstract Bioprinted organoids integrate bioprinting technology with organoid research, enabling the simultaneous reconstruction of human tissue morphology and physiological function in vitro. This approach offers distinct advantages in organoid fabrication, particularly in terms of structural precision, tissue mimicry, and functional fidelity. By leveraging the complementary strengths of both technologies, bioprinted organoids allow for the fabrication of personalized, architecturally engineered models that more accurately replicate organogenesis, physiological processes, and disease progression. Herein, this review outlines the key advantages of bioprinted organoids, with a focus on their ability to precisely control morphology, dimensions, and spatial organization. Bioprinted organoids are further categorized into three types based on their cellular origins and summarize recent progress in their application for human tissue modeling. Finally, ongoing challenges and future possibilities are sketched out, offering insights for potential innovation and research directions in the field. Bioprinted organoids not only propel the advancement of organoid research but also drive the evolution of bioprinting technologies. This integrated approach represents a powerful synergy between biomanufacturing and clinical medicine to pave the way for a new era in biomedical science and personalized healthcare.
