However, the molecular stability of RNA agents still remains insufficient for clinical application. High porosity, tunable size, and ideal biodegradability and biosafety are a few of the characters of mesoporous silicon nanoparticles (MSNs) that render them a promising biomaterial carrier for RNA treatment.Materials and Methods: In this study, a novel miR-26a delivery system was constructed based on MSNs. Next, we assessed the miRNA protection of the delivery vehicles. Then, rat bone marrow mesenchymal stem cells (rBMSCs) were incubated with the vectors, and the transfection efficiency, cellular uptake, and effects on cell viability and osteogenic differentiation were evaluated.Results: The results demonstrated that the vectors protected miR-26a from degradation in vitro and delivered it into the cytoplasm. A relatively low concentration of the delivery systems significantly increased osteogenic differentiation of rBMSCs.Conclusion: The vectors constructed in our study provide new methods and strategies for the delivery of microRNAs in bone tissue engineering.Keywords: nanocarrier, microRNAs, osteoinduction, tissue engineering Yan JLu XZhu XHu XWang LQian JZhang FLiu MDove Medical Pressarticlenanocarriermicrornasosteoinductiontissue engineeringMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 497-511 (2020) |
