The authors have retracted this article. While trying to replicate this study they found that the polydatin could not recover the mRNA and protein expression of RUNX2, Osteopontin, DLX5, and OCN after lentivirus transfection. The authors believe that this could be due to contamination of lentivirus or the vector, or that polydatin was wrongly prepared in this study. All authors agree to this retraction.
