Further cell testing utilized fluorescent MEW scaffolds composed of a crosshatch design with 500 microns spacing and 5 layers. These were punched to 5mm diameter and sterilized with 70% ethanol for 30 minutes. Surface treatment with 0.1M sodium hydroxide was utilized to improve cell attachment by reducing the hydrophobicity of PCL scaffolds. MSC's were seeded at a density of 60,000 cells/scaffold in the same media mix utilized above. After 1 day, the media mix was changed to include fibroblast growth factor beta to improve cell expansion. Scaffolds
