Figure 3. Light micrographs of perivascular macrophages stained with PAS-haematoxylin.

Figure 3

All scale bars represent 10 μm. Perivascular macrophages (PVMs) surrounding cerebral blood vessels of (A, B) 6-week-old control mouse, (C, D) 12-week-old control mouse, (E, F) 6-week-old UfCB-exposed offspring mouse, and (G, H) 12-week-old UfCB-exposed offspring mouse were shown. B, D, F, H: Enlarged view of A, C, E and G: PVMs of control mice contained many PAS-positive granules, sized 0.9 μm (B, arrow) and 1.3 μm (D, arrow), in the cytoplasm. Many PAS-positive granules were enlarged in UfCB-exposed offspring (F, arrow: 2.6 μm; H, arrow: 3.0 μm).
