In Vitro Human Joint Models Combining Advanced 3D Cell Culture and Cutting-Edge 3D Bioprinting Technologies

Area of Science:

• Biomedical Engineering
• Tissue Engineering
• Rheumatology

Background:

• Joint-on-a-chip is an emerging technology for replicating joint functions in microscale systems.
• It aims to closely mimic pathophysiological conditions relevant to joint diseases.

Purpose of the Study:

• To detail the capabilities of joint-on-a-chip technology.
• To highlight its potential in studying rheumatic disease physiopathology, biomarker development, and drug screening.

Main Methods:

• Utilizes advanced 3D printing for precise control over cellular compartment architecture (chondrocytes, stromal cells, osteocytes, synoviocytes).
• Integrates fluid circulation, growth factor delivery, and physical stimulation (oxygen, pressure, mobility).

Main Results:

• The technology enables the creation of microscale systems that replicate diarthrodial joint functions.
• These systems mimic mobility, biomechanical aspects, and cellular interactions within the joint.

Conclusions:

• Joint-on-a-chip technology offers a novel platform for in-depth study of joint diseases.
• It holds significant promise for advancing the development of diagnostics and therapeutics for rheumatic conditions.
