Catalpol-Loaded Silk Fibroin Nanoparticle/GelMA Hydrogels Promote Autophagy-Mediated Angiogenesis for Vascular Regeneration in Limb Ischemia.
Limb ischemia is a severe manifestation of peripheral arterial disease with limited therapeutic options. Induction of therapeutic angiogenesis represents a promising strategy to restore blood perfusion. Natural bioactive compounds, particularly when integrated with biomaterial engineering, offer therapeutic potential w...
