Figure 6From: Cooperative effects in differentiation and proliferation between PDGF-BB and matrix derived synthetic peptides in human osteoblasts Calcification indexed by van Kossa staining for AC-100, PDGF, and PDGF/AC-100 combination. Increase in calcification was significantly higher in PDGF/AC-100 than control at days 5 and 10 (*p < 0.05).Back to article page
