Scientists at the German University of Duisburg-Essen have discovered a new type of blood vessel in the bones that provides most of the required blood supply.
The study shows that newly discovered capillaries, called transverse vessels (TCVs), penetrate the hard cortex of rat bones.
The new vessels act as a “short” pathway by transferring immune cells from the bone marrow to the affected area of the body, instead of the cells that the blood must “pick up” when they enter the end of the bone, through the bone marrow.
Bone, to leave the other end. When analyzing human bones, scientists discovered that we also have similar blood vessels in larger bones in our bodies.
Scientists hope that their revolutionary discovery will lead to the development of new therapies, using this blood flow and the “migration” of immune cells, to help treat inflammatory diseases, such as osteoporosis. In the study, fluorescent scientists were injected into long bones in mice.
The long bones are characterized by being solid and dense, they provide strength and support structure.
The findings, published in the journal Nature Communications, revealed long bones in mice fed with oxygen and nutrients by hundreds of newly discovered capillaries along the entire spine.
When the researchers examined small fragments of the human femur, they found the blood vessels themselves, although more intense , the exposed capillaries connect the inner and outer velum surrounding the bones.
It is believed to play a crucial role in helping to transport blood in and out of the bark of hard bone.
It was also discovered that this blood is rich in immune cells, which are transported by capillaries from the bone marrow to the bloodstream.
Scientists believe that re-modeling “TCV” may play a role in fracture healing.
