Figure 5. Quantification of cell proliferation, VIC density and SMA expression in mouse models of valve disease.
(A) The number of pHH3 positive nuclei/total nuclei in aortic valve leaflets was calculated for 3 independent sections of 3 hearts per genotype. (B) The total number of nuclei per μm2 of aortic valve leaflet area was calculated for 3 independent sections of 3 hearts per genotype. (C) The number of SMA positive cells/total nuclei in aortic valve leaflets was calculated for 3 independent sections of 3 hearts per genotype. Cohorts of oim and Postn mice and controls were evaluated at 4 months of age. Klotho null mice and WT littermates were evaluated at 6 weeks of age. Statistical significance was determined by paired student’s t-test. * is p≤0.05.
