Osteoblastogenesis is an essential part of the bone healing process. Insulin has been shown to improve bone healing in both normal and diabetic bone healing models. In addition, insulin mimetic compounds such as Zinc chloride (ZnCl2) and Vanadyl acetylacetonate (VAC) have also been shown to improve bone healing in these models as well. The purpose of this study was to determine the effects of vanadium compounds VAC and Vanadium (II) sulfate (VSO4) in osteoblast proliferation and function. In addition the mechanisms by which growth and function are facilitated by these Vanadium compounds were also evaluated. In …

Researchers have begun investigating whether insulin mimetics such as ZnCl2 could promote bone healing in both non-diabetic and diabetic fracture healing similarly to insulin. Our research focused on understanding the mechanism by which ZnCl2 affects chondrogenesis, an important component of bone fracture healing. The increases in proteoglycan deposition and cell proliferation seen in our data may be a result of ZnCl2 induction of the IGF-1 pathway. When the VEGF pathway was inhibited in ZnCl2- or insulin-treated cells significant decreases in proteoglycan deposition occurred on day 7 and 14 (P=0.007 for ZnCl2, P=0.028 for insulin) when compared to controls. This data …
