Function-First Organoid Engineering for Regenerative Medicine: Current Challenges and Future Perspectives.

Engineering Neural Organoids: Technological Advances and Translational Frontiers.

Neural organoids have transformed experimental neuroscience by enabling human-specific models of brain development, function, and disease. Emerging at the intersection of stem cell biology and tissue engineering, these self-organizing systems recapitulate key aspects of neurogenesis, gliogenesis, and circuit formation within a controllable in vitro context. Advances in guided patterning, vascularization, and electrophysiological monitoring have enhanced structural and functional fidelity, enabling the study of dynamic processes previously inaccessible in human models. Beyond developmental biology, neural organoids have broad translational applications, including modeling neurodevelopmental and neurodegenerative disorders, screening pharmacological compounds, and testing regenerative strategies. Integration with microfluidics, bioelectronic interfaces, and computational modeling further expands their analytical capacity, transforming organoids into modular and quantifiable platforms for mechanistic and therapeutic discovery. Despite this progress, key challenges remain, including limited maturation, inter-organoid variability, and incomplete physiological integration. Addressing these limitations requires standardized differentiation protocols, robust functional benchmarks, and cross-disciplinary collaboration. The goal is not to replicate the brain in miniature, but to reconstruct its organizing principles in an experimentally accessible system. From this perspective, neural organoids serve as a bridge between biology and technology, offering new insights into human neural complexity while advancing neuroscience and medicine.

Emerging Role of Human Organoids in Drug Discovery and Development: Current Advances and Challenges

Biomaterials in organoid research: current state and future directions

Organoid research has fundamentally reshaped in vitro approaches to modeling disease, drug response, and developmental processes. While the potential is great, the technology is limited by reproducibility and physiological accuracy challenges that arise partly from the shortcomings in extracellular matrix mimicking biomaterials that influence morphogenesis, differentiation, and functionality. In recent years, biomaterials for organoid systems have developed from biologically derived but poorly defined matrices toward tunable, dynamic, and modular systems that allow for precise control and better reproducibility of the microenvironment. This Mini-Review summarizes recent advances, with a focus on the last 3 years, in natural, synthetic, and hybrid biomaterials, highlighting engineered ECM–derived hydrogels, modified natural polymers, and synthetic systems with tunable viscoelasticity, degradability, and bioactive components. Furthermore, emerging trends and technological integrations, comprised of 3D and 4D bioprinting, granular hydrogels, organ-on-a-chip platforms, and AI-driven methods, will be discussed, which together support scalable and data-driven optimizations in organoid research. Summarized, these developments demonstrate the transition from a generic matrix-based culture toward engineered, tunable, and dynamic microenvironments, demonstrating biomaterial design as a fundamental element for next-generation organoid systems.

Engineering functional human vasculature: iPSC-derived vascular cells and organoids for disease modeling and translation.

Human vascular function depends on tightly coordinated structural, mechanical, and cellular interactions, yet these features remain difficult to recapitulate in vitro. Induced pluripotent stem cells (iPSCs) enable efficient generation of vascular cell types, including endothelial cells, smooth muscle cells, and pericytes, but current systems often lack functional maturity and physiological relevance. Recent advances in vascular organoid engineering provide new opportunities to address this limitation. By integrating self-organization, co-culture, and bioengineering approaches, iPSC-derived systems can form three-dimensional vascular networks with increasing physiological relevance. Emerging evidence from studies of iPSC-derived vascular systems, spanning both two-dimensional differentiation models and three-dimensional organoid platforms, highlights the critical roles of hemodynamic cues, including shear stress and perfusion, together with metabolic and immune signaling, in driving the coordinated maturation of endothelial and mural compartments. These platforms enable modeling of key vascular pathologies, including inflammation, vascular remodeling, and barrier dysfunction, while gene editing further facilitates mechanistic investigation in patient-specific contexts. Together, iPSC-derived vascular systems provide a scalable and physiologically relevant platform for disease modeling, drug discovery, and regenerative medicine.

Advances in organoids for personalized medicine: from technological development to clinical application

Organoids, three-dimensional cell culture models derived from patient tissues or stem cells, have emerged as a cutting-edge technology in personalized medicine, owing to their remarkable ability to closely recapitulate in vivo tissue architecture and function. This review provides a comprehensive overview of the technological evolution and construction methodologies of organoids, highlighting their significant applications in oncology, genetic disorders, infectious diseases, and drug screening. This review examines how organoids enable precision medicine by preserving genomic fidelity, predicting drug sensitivity, and creating disease models via gene editing. Despite these advances, organoid technology faces several technical challenges that impede its full clinical translation. Addressing these obstacles is critical for realizing the potential of organoids in individualized therapeutic strategies. This article aims to delineate current progress and future directions in organoid research, furnishing a theoretical foundation and guiding future investigations towards enhancing personalized treatment paradigms.
