Elastic Porous Microspheres/Extracellular Matrix Hydrogel Injectable Composites Releasing Dual Bio-Factors Enable Tissue Regeneration

Investigators developed a biomaterial system consisting of elastic porous poly(l-lactide-co-ε-caprolactone) microspheres mixed with ECM hydrogels as injectable composites with interleukin-4 and insulin-like growth factor-1 dual-release functionality.
