Vascular Tissue Engineering: Effects of Integrating Collagen into a PCL Based Nanofiber Material

Figure 1

The analysis of SEM images shows that median fiber diameters of our scaffolds range from 184 nm (PCL/Coll 5%) to 265 nm (PCL) (a). Fiber diameters do not assume Gaussian distribution, as the more detailed histogram (b) depicts. (c)–(g) show SEM images of our scaffolds’ surface magnified 5k-fold (scale bar 2 μm).
