Abstract
The present study demonstrates the development of polysaccharide gelatin naturapolyceutics hydrocolloidal biomatrix with cobalt nano-additives for restructuring native tissue vasculature for tissue regenerative applications. The engineered Gelatin/Aloevera mucilage polysaccharide/nanoscaled Cobalt (GAC) hydrocolloids resulted from the intermolecular interactions between the aloevera mucilage, cobalt nano-therapeutic and gelatin. GAC hydrocolloid showed enhanced thermal stability in comparison with control Gelatin/Aloevera mucilage (GA) hydrocolloid. FTIR analysis validated that the reinforcement of aloevera mucilage and cobalt nano-therapeutic did not affect the structural integrity of the gelatin molecule. 3-Dimensional sponge-like orientation of GAC hydrocolloid facilitates perfusable biomatrix for access to nutrients and gaseous exchange for high cell adhesion and proliferation. The combined therapeutic efficacy of mucilage polysaccharides, biodegradable nanoscaled cobalt and bio-polymer enhanced the pro-angiogenic capability of the hydrocolloids by stimulating Vascular Endothelial Growth Factor (VEGF) response at wounded tissue for faster healing. The experimental outcomes on in vivo angiogenesis profiling further confirmed the development of micro vessel in chick embryonic model and regeneration of blood vessels in zebra fish model. This study opens up the potential of mucilage polysaccharides in stimulating high density angiogenesis and conveys the progress of a biocompatible, biodegradable mucilaginous hydrocolloid as an effective bio-adhesive for vascular development in soft tissue regeneration.
