MicroRNAs (miRNAs) are critical regulators in organ development. Among them, miR-191 is known to be regulated in early embryogenesis and dysregulated in cancer. This role in undifferentiated tissues suggests a possible part of miR-191 also in bone marrow derived mesenchymal stem cells (BMSCs) physiology. Here, we report that miR-191 decreased MMP expression and migration of BMSCs. Conditioned media of miR-191 overexpressing BMSCs block VEGF expression, and inhibit angiogenesis of HUVECs. Under osteogenic culture conditions, inhibition of miR-191 significantly induces bone formation. Moreover, our studies showed miR-191 might influence chondrogenesis of BMSCs by directly targeting CCAAT Enhancer Binding Protein Beta (CEBPB). Taken together, here we demonstrate the role of miR-191 in differentiation, migration and paracrine function of BMSCs.

MicroRNA-191 调节间充质干细胞的分化和迁移及其对血管生成的旁分泌作用

MicroRNAs (miRNAs) 是器官发育的关键调节因子。其中,已知 miR-191 在早期胚胎发生中受调节,在癌症中失调。这种在未分化组织中的作用表明 miR-191 也可能存在于骨髓间充质干细胞 (BMSC) 生理学中。在这里,我们报告 miR-191 降低了 MMP 的表达和 BMSCs 的迁移。过表达 miR-191 的 BMSCs 的条件培养基阻断 VEGF 表达,并抑制 HUVEC 的血管生成。在成骨培养条件下,抑制 miR-191 显着诱导骨形成。此外,我们的研究表明 miR-191 可能通过直接靶向 CCAAT 增强子结合蛋白 Beta (CEBPB) 来影响 BMSCs 的软骨形成。总之,我们在这里证明了 miR-191 在 BMSCs 的分化、迁移和旁分泌功能中的作用。
