Everyone knows that playing sports strengthens the body. But how this works, scientists managed to find out at the Research Institute at the children's medical center in Utah.
According to the journal Nature, the object of the study was the leptin receptor cells, which produce osteolectin. Peri-arteriolar cells are rapidly dividing, short-lived, increasing in number after fracture and depleting with aging. They are located only near the arteriolar blood vessels of the bone marrow and are involved in the synthesis of stem cells, but their growth decreases with age.
Scientists conducted an experiment with mice. Running wheels were installed in the cage, and the mice were constantly exercised. As a result of training, the muscles of the rodents strengthened. A laboratory study showed an increase in osteolectin cells around the arterioles.
Thus, scientists conclude that cell regeneration in the bone marrow occurs due to mechanical stimulation. With physical exertion and regular training, the impulse is transmitted through the arteriolar vessels to the bone marrow, which leads to the renewal of the bone-forming cell, and as a result, immunity and bone tissue are strengthened.
