In vivo effects of the PLGA-transfected iMEF composite on vessel formation upon subcutaneous implantation into rats. (a) Schematic diagram showing the transfected iMEFs seeded on electrospun PLGA scaffolds implanted into the dorsal subcutaneous space of the mice. (b) Scanning electron microscopy image of the PLGA scaffold (b1) and seeded cells (b2) on the PLGA scaffold (). (c) General observation of harvested PLGA implants at 5 weeks. (d) Immunofluorescence staining for CD31 (vascular formation displays green fluorescence) and the average number of vascular structures in a high-power field for each implant (). (e) Quantification in each group is based on immunofluorescence staining.
