Skin healing as in the film: This technology is the end of chronic wounds – Trends of the future

The ability to skin injuries heal quickly and painlessly arguably the most common medical reference in science ficition movies. In series like Star Trek doctors can heal any injury to the skin quickly and easily with a kind of radiation. What looks like pure science fiction, is actually now much closer to reality than you might think.

self-healing - This material heals itself

support in wound healing

A team led by Mark Bass by Department of Biomedical Science at the University of Sheffield uses small ultrasonic transmitter and the self-healing powers of the skin to speed up and support. The devices are so small that they can be used on TV by hand. Of course, no immediate cure as in Star Trek takes place, but a study showed that the healing time of injuries could be reduced by 30 percent. This is especially important because the duration of exposure of the wound and thus also the risk of infection is reduced.

Interestingly, this technology is for people whose healing is already compromised anyway. From the age of 30 years, the healing can last may increasingly longer. In extreme cases (mostly in patients older than 60) can even become chronic skin lesions which, although rarely life threatening, but at least is very prejudicial. In many cases it is necessary to amputate limbs affected.

Natural processes are activated

With its ultrasonic treatment, the researchers activate resting cells and speed up the healing process. Based on such accelerated self-healing powers are also the skills of many superheroes to heal injuries immediately.

embryo in the womb is able to heal injuries without scarring. These skills go continuously lost after birth. The sonication “remembers” the body as it were to his own healing powers. Unlike many drug treatments, the method is very low risk, as only natural processes are supported.

cell activation by vibrations

The ultrasonic waves loosen microvibrations the membranes of skin cells and open so their calcium channels. The calcium flux is essential for the signaling pathways of the cell and controls many of the cellular functions. In addition, by the treatment inside the cell produces a calcium gradient that draws the cell toward the breach. The wound margins are thereby brought together and wound healing additionally accelerated.

There the team was able to demonstrate the effect already in patients with venous ulceration of the leg. Among other things, so patients were treated with the “diabetic foot”.

In the near future the team will create larger clinical trials to explore the boundaries and limitations of the technology. In the long term bass but considers it possible that the scar-free healing, the embryos are able, even in adult humans can be resurrected
