Figure 3.

Pericyte coverage of SVZ capillaries is not increased following irradiation and during aging. Scale bars = 50 µm. The p-value was determined using the Mann–Whitney U-test (B) and the Kruskal–Wallis test (C).

A. SVZ capillaries presented laminin immunostaining but had partial desmin mural coverage, with this marker being absent from regions with numerous nuclei (dashed line).

B. The pericyte coverage of SVZ microvessels was examined using electron microscopy.

C. The quantification of NG2/pericytes on SVZ capillaries following irradiation and during aging. The mean ± SD is shown and the number of mice is indicated within the bars.

D. A NG2/pericyte on a SVZ capillary is shown (arrowhead).
