The effects of recombinant human insuline-like growth factor-1 and basic fibroblast growth factor on the proliferation of periodontal ligament cells / 实用口腔医学杂志

Objective: To observe the effects of human insuline like growth factor 1 (rhIGF 1) and/or basic fibroblast growth factor (bFGF) on the proliferation of periodontal ligament (PDL) cells. Methods: PDL cells were exposed to rhIGF 1 and/or bFGF at various concentrations for 1,3,5 and 7 d respectively. The proliferation of the cells was studied with MTT assay.Results: rhIGF 1 at 3.125～25.000 ?g/L or bFGF at 0.1～10 ?g/L promoted PDL cells growth in a dose and time dependant way.3.125 ?g/L of rhIGF 1 and 1 ?g/L of bFGF showed stronger effects on cell growth than both used individually.Conclusion: rhIGF 1 and/or bFGF can promote the proliferation of PDL cells.
