FIGURE 5.
Capillary density in both atria and ventricles from control and LKB1-KO mice at 4 and 12 weeks of age. A, top and middle panels, representative histological sections of CD31 immunohistochemistry staining in atria and ventricles. Bottom panel, mean capillary density in control (open bars) and LKB1-KO (filled bars) mice. Values are expressed as mean ± S.E. *, p < 0.05; **, p < 0.01; n = 4–6 in each group. B, mRNA (left) levels and protein levels with the representative blots (right) of VEGF expression in atria and ventricles. Values are expressed as mean ± S.E. *, p < 0.05; **, p < 0.01, n = 6–8 in each group.
