| Sumario: | Electrospun nanofibrous membranes (NFM) can serve as a physical barrier, employed to confer polypropylene (PP) mesh with anti-adhesion capability for repairing abdominal wall hernias. Still, the feasibility of NFM combined with different PP meshes was poorly researched. In this study, nanofiber containing composite meshes with three PP substrates were produced by integrating the NFM barrier compositing poly (lactic-co-glycolic acid) and polycaprolactone (PLGA/PCL) into each PP mesh. Tensile mechanical test results revealed that the PP component played a dominant role in the mechanical support, and this structure has not deteriorated in any case during the process. In vitro cell studies showed that the PP mesh with a higher density was significantly beneficial for cell proliferation within 3 days of seeding, while the one with lower density exhibited notable cell proliferation after a culture of 5 days. All the meshes had excellent biocompatibility. Moreover, an intraperitoneal implantation rabbit model was used to assess the anti-adhesion effects and tissue compatibility. The results revealed that the NFM barrier could be incorporated into the lightweight PP mesh to yield the composite mesh with superior anti-adhesion property and tissue compatibility. |
