摘要
Insulin, an old but still actual molecule, has many roles in various cellular processes including bone formation and also angiogenesis. Insulin effects on different cell types were investigated, and we intended to check its effect on dental pulp cells (DPC) during osteoblast differentiation. First, bone differentiation ability of isolated dental pulp cells was assessed by alizarin red (AR) staining. Insulin increased dental pulp cell proliferation after 25 hours of culture. It increased mRNA expression of osteogenic markers such as Col1, RunX2, ALP, Osc, Mef2C and expression of genes involved in TGF b pathway such as Smad3, TSP1, VEGF at different time points.
