Quantitative analysis of alizarin red staining. rhBMP2_108 demonstrate a concentration dependent increase in alizarin red staining (All experiments were conducted in triplicate with three independent experiments (n = 9). Data represents means +/− SEM. * denotes significant difference between two groups, p < 0.05; ** denotes significantly higher than all other modalities, p < 0.05, # denotes control samples significantly lower than all other treatment modalities, p < 0.05)
