Trabecular and endocortical bone surfaces in the rat: Modeling or remodeling?

There is conflicting evidence as to whether bone resorption and bone formation are coupled in the site‐specific manner that is typical of bone remodeling in the rat. The aim of this study was to elucidate this controversy further by analysis of tibial and vertebral cancellous and endocortical bone in rats of different age groups with a combination of in vivo fluorochrome labeling with cement line staining.
