The study successfully developed a lipoplex system for delivering FGF-2 encoding plasmid DNA, which demonstrated significant transfection and FGF-2 expression ability in vitro, promoting cell proliferation and migration.
Background Developing an alternative and efficient therapy for wound healing has been an important research topic for pharmaceutical sciences. A straightforward but effective system for delivering fibroblast growth factor-2 (FGF-2) encoding plasmid DNA (pFGF-2) for wound healing therapy was aimed to develop in this study. Methods In order to provide the delivery of pFGF-2, a delivery vector, namely, cationic lipid nanoparticle (cLN) was developed by the melt-emulsification process, complexed with pFGF-2 to form a lipoplex system and further characterized. The pFGF-2 binding and protecting ability of lipoplexes were evaluated. The cytotoxicity and transfection efficiency of the lipoplexes, FGF-2 expression levels, and in vitro wound healing ability have been investigated on the L929 fibroblast cell line. Results The obtained lipoplex system has a particle size of 88.53 nm with a low PDI (0.185), and zeta potential values of 27.8 mV with a spherical shape. The ability of cLNs to bind pFGF-2 and protect against nucleases was demonstrated by gel retardation assay. Furthermore, the developed FGF-2 carrying lipoplexes system showed significant transfection and FGF-2 expression ability comparing naked plasmid. Finally, scratch assay revealed that the developed system is able to promote in vitro cell proliferation/migration in 48 h. Conclusion Promising results have been achieved with the use of lipoplexes carrying pFGF-2, and this approach could be considered as a potentially applicable concept for the future gene-based wound healing therapies.
