Osteogenic gene expression of osteoblasts grown on tissue culture plastic in the presence or absence of soluble QHREDGS on the indicated day (D): (A) alkaline phosphatase, (B) osteocalcin, (C) type I collagen and (D) bone sialoprotein. Gene expression was normalized by dividing by the expression of the housekeeping gene β-actin. Data presented are the mean ± SEM (n=3) and the lines indicate statistical significance (P < 0.05, unless noted, n=3).
