Maybe there are still unknown structures in human bones – Science – iTech

The study, published in the scientific journal Nature Metabolism, indicates that these capillaries, or small tunnels seen in laboratory mouse leg bones, could be vital for the transport of immune cells from the bone.

Certainly, something in the bones of the mouse does not automatically mean that the same person will be present, and the time required to officially confirm this discovery in the human context can be very long. However, not in this case.

One of the researchers decided not to delay and sink into a magnetic resonance device. As a result, it became apparent that such a capillary network could well be a human bone.

It is known that there are blood cells in the bone marrow capable of moving very quickly from the bone marrow to the circulatory system. But how exactly do these cells come out of the bone is not known.

Now, with the help of a special medical procedure, when a special substance is injected into the human bone, which then enters the blood, we have found wires indicating unknown capillary bones.

To detect microscopic tunnels in the bones, the researchers used a special chemical that gave the mouse a transparent appearance. This chemical removes opaque components such as bone fat. As a result, hundreds of unprecedented capillaries have been clearly exposed to the eyes by researchers using several different microscopes.

This discovery was a big surprise for the researchers. "21. in the century, it is unlikely that you will discover anything new in the human body, "said Matthias Gunzer, senior scientist at Live Science.

Gunzer wanted to know if there were such structures in human bones. So he willingly let his foot explore. He spent an hour in a magnetic resonance machine, which was not in vain. Although the capillaries are not visible, bone tissue has revealed suspicious holes that could indicate the existence of a capillary.

In addition, in another study published last year in the scientific journal Nature Neuroscience, scientists have discovered similar capillary networks in the skull.
