Background aimsSustained gene delivery could be particularly necessary in modulating gene expression in healing intrasynovial tendons and may be a promising approach for preventing adhesions.MethodsPolylactic-co-glycolic acid nanospheres were prepared and were then incorporated with plasmids expressing enhanced green fluorescence protein and miRNA for inhibiting the transforming growth factor-β1 gene expression.ResultsWe demonstrated that cultured tenocytes could be effectively transfected by means of nanosphere/plasmid. The expression of transforming growth factor-β1 is significantly downregulated in healing chicken flexor tendon treated with nanosphere/plasmid. Histology analysis did not demonstrate any significant inflammation or necrosis in tendons injected with nanosphere/plasmid after surgery.ConclusionsNanosphere/plasmid may be a promising non-viral vector for gene therapy of the injured flexor tendon.
