Figure 1From: Lack of anabolic response to skeletal loading in mice with targeted disruption of the pleiotrophin geneExpression levels of PTN gene as a function of duration of loading. The y-axis represents fold increase in the PTN gene in response to four-point bending on tibia and the x-axis represents duration of loading on 10-week female B6 mice. Values are mentioned as mean ± SD, ap < 0.01 vs. non-loaded tibiae, bp < 0.05 vs. 2-days (Post Hoc test, ANOVA), N = 5.Back to article page
