Bilayer PCL/GelMA microneedle patch codelivers deferoxamine and primed mesenchymal stem cell secretome for enhanced diabetic wound repair.
Chronic diabetic wounds remain refractory to healing due to persistent inflammation, impaired re-epithelialization, extracellular matrix dysregulation, and microvascular dysfunction. Here, we report a mechanically robust and biologically integrated microneedle (MN) platform composed of a poly(ε-caprolactone) (PCL) core...
