Figure 4.

Histopathology sections of experimental CNV after young or old BMT into young recipient mice. Sections were stained with hematoxylin and eosin. CNV lesions were significantly less severe in young mice that received young BM ([A], Y-to-Y) when compared with young mice transplanted with old BM ([B], O-to-Y). White arrowheads show the margins of the CNV membranes. (C) A significant difference in lesion size was observed between the two transplanted groups when the mean cross-sectional area was quantitatively analyzed. Magnification: ×100; scale bar: 100 μm.
