“Changes in bmp2, runx2 and osteocalcin (bglap) mRNA expression in PDPCs seeded on (a) Gel and (b) HA/Gel scaffolds. Data are expressed as fold-regulation which represents fold-change results in a biologically expressive manner. Fold-regulation is equal to the fold-change (2−ΔΔCt) for fold-change values greater than one, which indicate an up-regulation. Fold-change values less than one indicate a down-regulation: in this case the fold-regulation is the negative inverse of the fold-change (−1/2−ΔΔCt). a = p < 0.05 vs CTRL; b = p < 0.05 vs 25/75 scaffolds; c = p < 0.05 vs 60/40 scaffolds.”
