Abstract: Objective: To investigate the effect of advanced glycation end products ( AGEs) on the proliferation of human periodontal ligament stem cells ( HPDLSCs). Methods: HPDLSCs were isolated by limited dilution of culture cells for single cell clone. The osteogenic differentiation capacity of HPDLSCs was evaluated by Alizarin red staining. The adipogenic differentiation capacity of HPDLSCs was evaluated by oil red staining. HPDLSCs were induced with different concentrations of AGEs, The proliferation of HPDLSCs was assayed by MTT, Real time quantitative reverse transcription polymerase chain reaction (real time PCR) was performed to detect the differences of gene expression between the control group and experimental group. Results: After 21 days induction,Alizarin red staining showed mineralization nodules were formed, oil red staining showed lipid droplets were formed. Different concentrations of AGEs had different effects on the PDLSCs proliferative capacity. High concentrations (100mg/L, 200mg/L) significantly inhibited the proliferation of PDLSCs. Low concentration (1mg/L, 10mg/L) had little effect on the proliferative capacity of PDLSCs. After 3 days, the expressions of cell cycle gene (cyclinD1) in the experimental group were lower than those in the control group, the expressions of HSG in the experimental group were higher than those in the control group (P<0.05). Conclusion: High concentrations of AGEs reduced the proliferation capacity of HPDLSCs,and changed the expressions of HSG and cyclinD1 mRNA levels.
