(a) Schematic showing the fabrication of electrospun P(VDF-TrFE) and P(VDF-TrFE)/ZnO scaffolds, hMSC seeding, and subsequent implantation into Wistar rats. (b) Histological examinations of fibrous scaffolds with or without pre-seeded hMSCs after implantation in rats for 7 days, and stained with Masson’s trichrome. Blood vessels developed in connective tissue adjacent to scaffolds as distinguished by yellow dashed lines, and collagen was found in all scaffolds (green). P(VDF-TrFE)/ZnO-1 and P(VDF-TrFE)/ZnO-2 contained 1 wt% and 2 wt% ZnO, respectively. Reproduced with permission from [177], published by Springer, 2017.
