Abstract EN
Delivery of osteogenesis-promoting microRNAs (miRNAs) is a promising approach to enhance bone regeneration.
In this study, we generated nanocomplexes comprising the novel cell-penetrating peptide R9-LK15 and miR-29b and investigated their effects on osteogenic differentiation of bone mesenchymal stem cells (BMSCs).
R9-LK15/miR-29b nanocomplexes were prepared and characterized.
The transfection efficiency, cell viability, and osteogenic differentiation were investigated.
The results showed that R9-LK15 maintained the stability of miR-29b in serum for up to 24 h.
Moreover, R9-LK15 efficiently delivered miR-29b into BMSCs; the transfection efficiency was ~10-fold higher than that achieved using Lipofectamine 2000.
The Cell Counting Kit-8 assay showed that R9-LK15 and R9-LK15/miR-29b nanocomplexes had negligible cytotoxic effects on BMSCs.
Delivery of R9-LK15/miR-29b nanocomplexes promoted osteogenic differentiation of BMSCs and extracellular matrix mineralization by upregulating alkaline phosphatase expression and downregulating histone deacetylase-4 expression.
In general, we developed a novel miRNA delivery system that has a high transfection efficiency and promotes osteogenic differentiation.
