Figure 7. Quantification of patent bone marrow blood vessels.

Figure 7

The volume of patent bone marrow blood vessels per tissue volume ratio and the number of patent bone marrow blood vessels from young and old male Fischer-344 rats were quantified from barium sulfate-perfused sections. The volume of patent bone marrow blood vessel per tissue volume (a) did not differ between ages; however, the number of patent bone marrow blood vessels (b) was lower with old age. Values are means ± S.E. *Denotes a significant (p < 0.05) difference from young rats.
