Characterization of Olfactory Ensheathing Glial Cells Cultured on Polyurethane/Polylactide Electrospun Nonwovens

Figure 1

SEM micrographs of PU/PLDL nonwovens (right) and bar graphs (left) displaying fiber diameters. Weight ratios of PU/PLDL: (a, b) 5/5, (c, d) 6/4, and (e, f) 8/2. Thickness of the fibers depends on the blend composition; that is, the more PU in the blend the thicker and more regular the fibers. Some beads are created along the fibers; however, they were not taken into consideration in the average diameter calculation.
