Preparation of PVA/hFDM and ciprofloxacin-loaded PVA/hFDM. (A) Schematic illustration of the overall process in fabricating PVA/hFDM and ciprofloxacin-loaded PVA/hFDM. (B) Microscopic image of decellularized hFDM on TCP and the surface of TCP right after the transfer of hFDM into PVA hydrogel. Scale bar is 100 μm. (C) Immunofluorescence of FN in the PVA/hFDM. (D) Cross-sectional view of the interface (dashed red line) between PVA and hFDM. Scale bar is 50 μm. (E) Loading of ciprofloxacin with different initial concentrations into PVA hydrogel and (G) the release profile over 24 h in PBS at 37 °C. FN: fibronectin; hFDM: human lung fibroblast-derived matrix; PVA: polyvinyl alcohol; TCP: tissue culture plastic.
