Used in research to study tissue repair and fibrosis, particularly in connective tissue diseases. Supports cell adhesion and proliferation in vitro, making it valuable for cell culture applications. Investigated for its role in wound healing, bone formation, and cartilage regeneration. Also employed in immunoassays and protein interaction studies due to the Fc tag, which allows easy detection and purification. Potential therapeutic target in fibrotic disorders and osteoarthritis.
