Bone/cartilage organoid on-chip: Construction strategy and application.

Area of Science:

• Biotechnology
• Regenerative Medicine
• Biomaterials

Background:

• Developing accurate ex-vivo models for bone and cartilage disorders remains a significant challenge, bridging the gap between cell cultures, animal models, and human physiology.
• Existing models often fail to fully replicate the complex microenvironment and biological functions of native bone and cartilage tissues.

Purpose of the Study:

• To introduce the novel bone/cartilage organoid-on-chip (BCoC) platform concept.
• To review the fundamental modules and integration strategies for BCoC systems.
• To discuss current disease models, challenges, and future directions for ex-vivo therapeutic strategies.

Main Methods:

• The review focuses on the organoid-on-a-chip technique, specifically adapting it for multi-tissue bone and cartilage constructs.
• It details the orchestration of basic modules within a single microfluidic system to emulate physiological conditions.
• The BCoC system is designed to replicate essential tissue elements, biological functions, and pathophysiological responses.

Main Results:

• The BCoC platform demonstrates potential for revolutionizing basic research and drug screening for bone/cartilage diseases.
• It offers a more faithful emulation of biological functions and disease responses compared to traditional models.
• The system aims to provide a generic ex-vivo tool for understanding and treating pathological conditions.

Conclusions:

• The BCoC platform represents a significant advancement in creating functional ex-vivo models for bone and cartilage disorders.
• Further development and application of BCoC systems are expected to deepen the understanding of diseases like osteoporosis and arthritis.
• This technology holds promise for accelerating the development of novel therapeutic strategies.
