Bone marrow in male and female rats

Abstract

Sex differences of high significance in the marrow weight relative to femur volume, as well as to body weight, were found in adult rats. A positive significant correlation was found between the femur volume and the marrow volume in both sexes, while a negative significant correlation between femur density and the marrow content (mg/mm3) exists only in male rats.

Effect of Feed Restriction on Peripheral Blood and Bone Marrow Cell Counts of Wistar Rats

“…Several studies have been reported on the relationships among body weight, bone volume, and bone marrow volume. Skeletal volume was in proportion to body weight in normal dogs [6] and femoral marrow volume was in proportion to bone volume in normal rats [5]. The femoral volume of young rats was reduced to 74% of that of controls by restricted feeding [12] and the tibia length of rats given 33 and 46% restricted feed intakes was 5 and 6-7 % less than that of the controls, respectively…”
