mRNA and protein levels of cyclin D 1 postoperatively. (a) mRNA level of cyclin D1 24, 36, and 72 hours postoperatively by real-time PCR. (b) Protein expression of cyclin D1 24, 36, and 72 hours postoperatively by western blot. n = 6, *P <0.05 and **P <0.01. H-BMMSC, hypoxia-conditioned bone marrow mesenchymal stem cells; N-BMMSC, normoxia-conditioned bone marrow mesenchymal stem cells; VEGF, vascular endothelial growth factor.
