Mechanical forces from running and walking that are transmitted along blood vessels in marrow induce the growth of new bone and immune cells in mice, scientists reported in Nature on February 24. The study is the first to demonstrate that mechanical forces can influence cellular growth and differentiation in the bone marrow, according to the authors, and provides a possible new explanation for how exercise strengthens bones and the immune system.
