Photo‐Responsive Decellularized Small Intestine Submucosa Hydrogels
Research Overview
Decellularized small intestine submucosa is rich in extracellular matrix proteins — collagen, laminin, fibronectin — and after mild decellularization supports cell adhesion, proliferation, and differentiation. But the conventional thermally crosslinked matrix is soft and unstable.
Methacrylate modification enabled photocrosslinking into more stable hydrogels; this study went further, developing decellularized submucosa modified with clickable handles for orthogonal crosslinking. The result is a photoresponsive biomaterial with tunable stability for tissue regeneration applications.
