Italian scientists published the most detailed photographs of nerve endings



    What you see in the announced photo is not at all the creation of the next artist, as an attractionist, who displayed his own associative fantasies on canvas. This is a photograph of the nerve endings of ordinary mice, obtained by using special technology.

    In the picture you can see the hair follicles, receptors, individual nerve endings. Upon receipt of the images, SNAP tagging technology was used. This technology is more than ten years old, but Italian scientists used it together with a new protein, the derivatives of which pass through the tissues and can be photographed.

    Previously, images of this class could not be obtained, since skin samples, although easy to obtain, are not very susceptible to fluorescence microscopy. The fact is that when you try to photograph something in the structure of the tissues using blue light, the tissues begin to fluoresce, and nothing can be considered. It is very difficult to introduce antibodies and usual SNAP tags into skin samples.

    Now scientists have circumvented the problem by using a special protein, the derivatives of which pass through various tissues of the body, and make such areas clearly visible against a dark background under fluorescence microscopy. The scientist himself is going to improve his method, and try to remove individual neurons of the brain or spinal cord at the time of their work.
