Abstract: Objective  To evaluate the effects of melatonin on the function of osteogenic differentiation of human periodontal ligament cells (hPDLCs). Methods  Melatonin was added into hPDLCs as experimental group. The blank control group was not added with melatonin. The effect of different concentrations of melatonin on proliferation of hPDLCs was assessed through MTT assay. Alkaline phosphatase (ALP) activity assay, ALP staining, Alizarin red S staining, Real-time PCR and Western Blot were used to observe the ALP activity, formation of mineral nodules, mRNA and protein expression of hPDLCs, respectively. Results  Compared to the control group, the proliferation of hPDLCs in the melatonin groups decreased. Melatonin was shown to enhance the ALP activity and expression of hPDLCs. The melatonin groups were observed more mineral nodules compared to the control group. Real-time PCR and Western Blot results showed that the mRNA and protein expression of Col-I, Runx2 and OSX increased by melatonin in different concentration. Conclusions  Melatonin has a promoting effect on the osteogenic differentiation of hPDLCs, and it has further research on the value of periodontal regenerative therapy.
