Age-specific effects on tissue markers in nonirradiated mice.

<p>The expression of <b>a</b>) CD31, E-selectin, thrombomodulin, ICAM-1, VCAM-1, Thy-1 and of <b>b</b>) CD45 and collagen IV^+ve cells is presented in sham-irradiated 0 Gy control mice at 2, 5, and 8 months of age. The relative number of specifically stained cells per 1000 nuclei around the left ventricle of the heart is given (mice at 2 months = 1, mean ± SEM, n = 8). Asterisks indicate p-values ≤ 0.05: *, p ≤ 0.01: **, p ≤ 0.001: *** compared to the 2-month group.
