Forces from walking or running are transmitted from the surface of our bones to the interior bone marrow along blood vessels. In reporting that discovery, researchers at Children’s Medical Center at UT Southwestern Medical Center show the mechanism by which new bone and immune cells are produced. Previous research had already shown exercise can improve bone strength and immune function, but this study, in the journal Nature, documents the mechanism by which it occurs. Another element of the study of laboratory animals showed when the bone-forming cells stopped sensing the pressure brought by exercise, the formation of new bone and immune cells was reduced.
