As a revolutionary 3D cell culture system, organoids bridge the gap between traditional 2D models and animal studies. This review synthesizes the current state of organoid engineering, from fundamental methods to transformative applications.
Organoid Construction
Key methods enable the generation of complex organoids:
Air-Liquid Interface (ALI) Culture: Ideal for modeling hollow organs and co-culturing with immune cells to study the tumor microenvironment.
Bioreactor Culture: Uses agitation to enhance nutrient exchange, supporting the growth of large, complex organoids like brains and enabling scalable production.
Vascularization: A critical advancement where organoids are integrated with blood vessels to improve survival and model neurovascular interactions.
Representative Models
The review details the construction of organoids for major organs, including kidneys, livers, lungs, brains, and intestines. These models are derived from pluripotent or adult stem cells using specific signaling pathways and scaffolds to recapitulate organ-specific structure and function.
Applications in Biomedicine
Organoids are transforming biomedical research:
Disease Modeling: They accurately mimic diseases like cancer, Zika virus infection, and cystic fibrosis.
Drug Screening & Biobanking: Patient-derived organoid biobanks allow for high-throughput drug testing and personalized treatment prediction.
Precision Medicine & Toxicity Assessment: They enable the selection of effective therapies for individual patients and provide human-relevant platforms for safety testing.
Application in TCM
Organoids offer a modern platform for TCM research, enabling the screening of active components, studying multi-target mechanisms, and evaluating the safety and efficacy of herbal compounds.
Frontier Technologies
The integration with cutting-edge technologies is pushing the field forward:
Gene Editing creates precise disease models.
Single-Cell RNA Sequencing reveals cellular heterogeneity.
3D Bioprinting allows for the precise fabrication of complex structures.
Artificial Intelligence analyzes complex organoid data for patterns and predictions.
Conclusion
Despite challenges in standardizing complexity and addressing costs, organoid technology is a powerful tool rapidly advancing our understanding of biology and disease. Its continued integration with other technologies promises to accelerate drug discovery and usher in a new era of personalized and integrative medicine.
