Guided tissue regeneration (GTR) to regenerate periodontal tissue involves placement of a cell-occlusive barrier membrane functionally excluding the gingiva and associated oral epithelium from the periodontal defect. Gingival connective tissue (CT) contains a rich vascular plexus and is a source of progenitor cells which could contribute to periodontal regeneration. We propose the use of a novel biodegradable and bioactive electrospun fibrous polycaprolactone (PCL) scaffold loaded with microspheres releasing basic fibroblast growth factor (bFGF) to promote gingival CT growth while maintaining a barrier to the oral epithelium. Scaffolds supported human gingival fibroblast proliferation and mesenchymal cell infiltration in a bFGF dose …
