Abstract

Neurotrophic factors play important roles in neuron survival, growth and differentiation. In the present research, the expression of multiple neurotrophins and their effects on cell migration were studied in the dental pulp stem cells (DPSCs). Human DPSCs from five patients were cultured. Expression of neurotrophins and their receptors were evaluated by PCR, immunofluorescent staining and ELISA. Scratch assay was performed in the presence or absence of neurotrophic factors. Level of phosphorylated-ERK was evaluated with Western blotting. Neurotrophins were expressed at various levels in the DPSCs. Treatment of 100 ng/ml BDNF or NT4/5 accelerated wound healing in scratch assay and elevated the expression of phosphorylated–ERK. The work indicated that neurotrophins promoted human DPSCs migration in vitro.
