FIG. 2.

Relative changes in osteogenic marker gene expression for HDPSCs cultured on 45S5 Bioglass scaffolds in vitro. (A) The effect of osteogenic culture conditions on the expression of osteogenic marker genes by HDPSCs on 3D Bioglass scaffolds after 2 and 4 weeks (n=3). The data for osteogenic conditions were normalized to corresponding controls cultured under basal conditions using the ΔΔct method. (B) The effect of 3D Bioglass scaffolds on osteogenic marker gene expression by HDPSCs cultured under basal or osteogenic condition on 3D Bioglass scaffolds for 2 and 4 weeks (n=3). The data for 3D culture were normalized to corresponding controls in monolayers using the ΔΔct method. The data are presented as log₁₀ of the mean 2^−ΔΔct±SD (*p<0.05, ***p<0.001).
