Histological analysis of bones from control and p38α knockout mice.

<p>(A) Representative images of calvarial sections stained with H&E. Right panel shows quantification of calvarial thickness (n = 5 independent animals). (B) Representative images of long bone sections stained with H&E. Quantification of trabecular area and trabecular number from tibiae sections are shown in the right panel (n = 3 (KO) and 4 (FF) independent animals). (C) Thickness and osteocyte count from cortical areas of long bone stained with toluidine blue (n = 3–6) (*p<0.05; **p<0.01; ***p<0.001).
