Vanadium Compound Treatment Modulates MC3t3-E1 Osteoblast Function

Year: 2025

Type: article

Abstract: Osteoblastogenesis plays a critical role in bone repair. Insulin and insulin-mimetic compounds, such as vanadium (IV) oxide acetylacetonate (VAC), have been reported to enhance bone healing in various models. This study aimed to evaluate the effects of vanadium compounds, VAC and vanadium (IV) oxide sulfate (VOSO4), on osteoblast proliferation and function. MC3T3-E1 pre-osteoblast cells were treated with insulin, ascorbic acid, and varying concentrations of VAC or VOSO4, and samples were collected at multiple time points over 21 days. We assessed cell proliferation, functional markers, and gene and protein expression. Our findings demonstrate that both VAC and VOSO4 stimulate MC3T3-E1 proliferation, increase calcium and proteoglycan deposition, and enhance phosphorylation of Protein Kinase B (Akt) over time. Gene expression analysis revealed that VAC treatment upregulated RUNX2, BGLAP, and TWIST2 at Day 7 compared to controls, with sustained expression patterns observed at Day 10. These results align with existing literature, supporting that VAC and VOSO4 promote osteoblastogenesis and may serve as effective adjuvants to accelerate bone regeneration during fracture healing.
