Dupuytren’s and Collagen: When Healing Turns to Fibrosis
Introduction
Collagen is the body’s most abundant protein and the foundation of connective tissue. But in Dupuytren’s contracture, this vital molecule turns from healer to hindrance. When collagen production spins out of control, it creates fibrous bands that tighten the hand and reduce mobility.
The Healing Cycle Gone Wrong
Normally, after injury or strain, fibroblasts produce collagen to close and strengthen tissue. When healing is complete, these cells switch off. In Dupuytren’s, they don’t — they stay active, transform into myofibroblasts, and keep depositing collagen Type III, creating stiff, rope-like cords.
Why Collagen Becomes Overactive
Several factors can trigger this cycle:
Inflammatory signals (TGF-β, PDGF) that over-stimulate fibroblasts.
Oxidative stress from smoking or metabolic imbalance.
Genetic mutations in collagen regulating genes.
Mechanical stress from repetitive use or hand injury.
Research Highlights
Studies in Matrix Biology show Dupuytren’s tissue contains abnormally high levels of collagen Type III and disorganized cross-linking. This structure reduces flexibility and makes cords resistant to breakdown, explaining why recurrence is common after treatment.
New Directions in Therapy
Scientists are testing ways to interrupt this process by:
Blocking TGF-β signaling to slow fibroblast activation.
Using collagenase enzymes to dissolve excess fibers.
Targeting oxidative pathways to reduce stress signals.
Practical Steps for Patients
Support collagen balance through antioxidant-rich foods and vitamin C.
Stay hydrated and stretch regularly to maintain tissue elasticity.
Avoid smoking and excess alcohol, both of which damage collagen architecture.
Conclusion
Dupuytren’s is a story of good biology gone bad. Understanding how collagen drives fibrosis opens doors to treatments that restore the body’s natural healing balance — and hope for long-term recovery.
