Abstract The relationship between bone and fat mass is complex. We examined two inbred strains of mice with phenotypic differences in marrow adiposity and bone mass. C3H/HeJ mice, with high bone mass and greater marrow fat, showed increases in gene expression for markers of brown-like adipocytes (Pgc1α, Ucp1) in their bone marrow compared to low basal levels in C57BL/6J mice. Mice with high bone mass may need a marrow thermogenic program to enhance osteogenesis.

Introduction

As the obesity epidemic continues to expand, attention has focused on the relationship between increased adiposity and bone mass. Several lines of evidence from epidemiologic studies demonstrate that fat tissue can influence skeletal function in di ...
