Organoids: A new frontier in precision medicine and engineering

Organoids have rapidly evolved into transformative platforms that bridge fundamental biology and clinical translation in the era of precision medicine. Derived from stem cells and engineered through biomaterial scaffolds, microenvironmental regulation, and genetic manipulation, organoids capture the three-dimensional (3D) structure, cellular diversity, and patient-specific features of human tissues with unprecedented fidelity. Recent advances in stem cell technologies, dynamic niche engineering, and high-content analytical tools have expanded their scope from static disease models to physiologically responsive systems capable of emulating organ-level functions. Applications now span regenerative medicine, infectious and inflammatory disease modeling, neurodegenerative and hereditary disorders, and oncology, where patient-derived organoids enable high-throughput drug screening and personalized therapeutic prediction. Furthermore, the convergence of organoid platforms with artificial intelligence, multi-omics profiling, and organ-on-chip devices enhances both mechanistic insight and translational relevance. This review synthesizes current progress in organoid engineering strategies and biomedical applications, while outlining persistent challenges and opportunities for interdisciplinary innovation. Collectively, these developments position organoid technology as a cornerstone for advancing precision medicine toward individualized, clinically actionable solutions. • Organoids provide physiologically relevant 3D models bridging basic research and clinical translation. • Advances in engineering strategies have improved organoid fidelity, maturity, and functional relevance. • Organoids enable high-fidelity modeling of diseases, drug screening, and therapeutic evaluation. • Integration with multi-omics and AI enhances the precision and predictive power of organoid platforms. • Organoid technology holds transformative potential for precision medicine and regenerative therapies.
