Figure 8From: Cooperative effects in differentiation and proliferation between PDGF-BB and matrix derived synthetic peptides in human osteoblasts Calcification indexed by van Kossa staining for TP508, PDGF, and PDGF/TP508 combination. Increase in calcification was not significantly higher in PDGF/TP508 than control at days 5 and 10 (*p < 0.05).Back to article page
