| Popis: | The physiological and pathological complexity of the wound healing process makes it more challenging to design an ideal tissue regeneration scaffold. Precise scaffolding with high drug loading efficiency, efficient intracellular efficacy for therapeutic delivery, minimal nonspecific cellular and blood protein binding, and maximum biocompatibility forms the basis for an ideal delivery system. This paper describes a combinational multiphasic delivery system, where biomolecules are delivered through the fabrication of coaxial electrospinning of different biocompatible polymers. The ratio and specificity of polymers for specific biofunction are optimized and the delivery system is completely characterized with reference to the mechanical property and structural integrity of bromelain (debridement enzyme) and salvianolic acid B (pro-angiogenesis and re-epithelialization). The in vitro release profile illustrated the sustained release of debriding protease and bioactive component in a timely fashion. The fabricated scaffold showed angiogenic potential through in vitro migration of endothelial cells and increased new capillaries from the existing blood vessel in response to an in ovo chicken chorioallantoic membrane assay. In addition, in vivo studies confirm the efficacy of the fabricated scaffold. Our results therefore open up a new avenue for designing a bioactive combinational multiphasic delivery system to enhance wound healing. |
