Figure 3. Responsiveness of FGF receptors and proteoglycans gene expression by Runx2 in osteoprogenitors.

Figure 3

Expression levels of FGF receptors (A) or proteoglycans (B) were determined by qPCR analysis in Runx2 null osteoprogenitors infected with vectors that either do or do not express Runx2 protein. Relative mRNA levels were plotted as fold change of exogenous Runx2 expressing cells over the GFP expressing control and normalized to 18S ribosomal RNA level. Statistical significance of differences was determined by Student’s T-test. Values with P < 0.05 are indicated by asterisks and values with P < 0.01 have two asterisks. Error bars represented Standard error of mean (SE) between three independent experiments. Panel B (right part) also contains data for two glycosaminoglycan (GAG) modifying enzymes that did not fit the scale of the graphs in Figure 4A.
