摘要:Objective: The aim of this study was to evaluate the influence of matrine on osteogenic differentiation of rat bone marrow-derived mesenchymal stem cells (BMSCs) as well as on bone metabolism in a rat rapid maxillary expansion (RME) model. Methods: In in vitro experiments, rat BMSCs were adopted and cell proliferation of BMSCs was measured. Meanwhile, the osteogenic differentiation of BMSCs was detected by alkaline phosphatase (ALP) activity assay, Alizarin red S staining and gene expression. In vivo bone regeneration was analyzed in a rat RME model. Eighteen rats were divided into 3 groups: one group without any treatment, one group receiving only RME, and a group with RME and matrine treatment. After 2 weeks, new bone formation was detected by Micro-CT and histology. Immunohistochemical staining was used to evaluate ALP and BMP2 expression. Results: Overall, we found that matrine upregulated cell proliferation dose-dependently. Also, ALP activity and mineralized matrix generation were enhanced. Moreover, the osteoblast-related gene expression (ALP, bone sialoprotein and osteocalcin) by BMSCs was also promoted. Micro-CT revealed that matrine significantly promoted in vivo bone formation after 2 weeks. Concomitantly, histological examination of haematoxylin-eosin, safranin-O and toluidine blue staining confirmed these findings. In addition, the levels of ALP and BMP2 in the palatal suture tissues of rats with matrine treatment were the highest among three groups. Conclusion: This work suggests that matrine regulates osteogenesis and enhances bone regeneration. Matrine treatment may be beneficial in improving the stability of maxillary expansion. © 2020 Elsevier Ltd
