Bone Matrix Maturation in a Rat Model of Intra-Cortical Bone Remodeling.

ABSTRACT: Matrix maturation within cortical bone is an important but oft-neglected component of bone remodeling because of the lack of a suitable small animal model. Intra-cortical remodeling can be induced in rodents by feeding virgin or lactating animals a low-calcium diet. The current study aimed to determine which of these two models is most suitable for studying intra-cortical matrix maturation. We compared intra-cortical remodeling in female rats fed a normal calcium diet (virgin/normal Ca), a low-calcium diet (virgin/low Ca), or a low-calcium diet during lactation (lactation/low Ca). The low-calcium diet was administered for 23 days (induction phase) followed by return to normal calcium for 30 days (recovery phase). At the end of induction, the virgin/normal Ca and virgin/low-Ca animals had n
