Fabrication of Biodegradable Polyester Nanocomposites by Electrospinning for Tissue Engineering
Figure 4
Fluorescence images of transverse sections of the nanofibrous structure. (a) and (b) Multifunctional scaffolds prepared by sequentially electrospinning of solutions as designated. (b) High magnification highlighting the clear layers. (c) Cell cultured in multifunctional scaffolds composed of PCL/collagen fibrous layer (outlined by red broken line) and PCL/BSA-FITC (green). High magnification (d) clearly showed cells attached onto PCL/collagen layers (#), but not onto PCL/BSA-FITC (*). Cell nuclei stained blue with DAPI. Scale bar: (a) and (c), 50 μm; (b), and (d), 20 μm. Reproduced from Journal of Experimental Nanoscience with permission from Taylor & Francis [20].
