Structural Development and Gravity

Abstract

Major research projects designed to elucidate the mechanisms by which gravity loading and/or fluid distribution alter bone formation and/or resorption in rat bone are reported. Projects completed include: (1) analysis of bone parameters in rats from 6 weeks to 68 weeks of age; (2) restricted access area in which rats on the model were not allowed to touch any side of the cage; and (3) the effect of dietary calcium levels on bone formation and resorption rates in controls and head-down rats.
