Expression of cytokine genes at four time points post-fracture.

<p>Data are expressed as fold-change in the expression of the gene in the fractured bones compared to unfractured bones of WT mice. We analyzed 3–4 animals/mouse strain at 1 and 3 days and 5–8 mice at 7 and 15 days post-fracture.*<i>p</i><0.05 <i>vs</i> WT unfractured bones, #<i>p</i><0.05 between fractured bones of the two lines of mice.
