YTHDF3 Enhances Osteogenic Differentiation of Bone Marrow Mesenchymal Stem Cells in Osteoporosis by Promoting TBX19 Expression

Cell Proliferation, EarlyView.
In this study, OP‐BMSCs were successfully isolated from OVX osteoporotic rats. Mechanistic investigations revealed that the RNA‐binding protein YTHDF3 significantly upregulates Tbx19 expression by enhancing the stability of Tbx19 mRNA. Elevated Tbx19 levels, in turn, activate key osteogenic molecules, effectively promoting the differentiation of OP ...
