Abstract

Challenged mouse models often require imaging and quantitative assessment of blood vessels and bone cell activities for a better understanding of the role of the vascular system. In this study we compared images of mouse hind limb long bone vascularisation after infusion of either barium sulfate or lead chromate-loaded silicon. The images were then analyzed through histology as well as low-resolution and synchrotron-radiation microtomography. We show that barium sulfate infusion provides the best vessel images and furthermore, that it is compatible with staining procedures used in bone histomorphometry and {CD31} immunohistochemistry. Bone marrow vascularisation displays large structural and spatial distribution heterogeneity, including large lobular clusters of sinusoids and an unexpectedly substantial amount of capillaries in the adipocytes-rich distal third of the tibia. For an unbiased assessment of bone vascular development/changes, these features must be taken into account.
