Fig. 2From: Mesh-like electrospun membrane loaded with atorvastatin facilitates cutaneous wound healing by promoting the paracrine function of mesenchymal stem cellsa–c SEM images of PCL/R, PCL/M, and PCL/MAT, respectively. SEM micrographs of electrospun fibers at a magnification of 100X (scale bar = 500 µm) and a magnification of 5000X (scale bar = 10 µm). d FTIR spectra of ATV powder, PCL/M and PCL/MAT; e Water droplet in contact with PCL/R, PCL/M, and PCL/MAT. f The stress–strain curves, g Young's modulus and h tensile strength. **Indicates significant difference of p < 0.01. ***Indicates significant difference of p < 0.001Back to article page
