When there is a wound on the body, we often groan with pain. But have you ever wondered why this happens? A recent research has shown that when skin cells are injured, they also send electric signals and communicate with each other. This process was previously considered associated with nerve cells (nerve cells).
Research found that these electric signals run very slowly, but they can reach the surrounding cells and activate them to heal wounds. These signs can affect a distance of about 500 micrometers.
What do scientists say?
The research took place at the University of Massachusetts Amharst, the US, where scientists Sun-Min U and Steve Creatures studied skin and kidney cells. They grown human skin and dog kidney cells on special types of chips. Then with the help of laser, they hurt controlled and recorded electric activity.
How does this electric system work?
Research found that the injured cells produce electric pulse operated by the flow of calcium ions. These pulse are similar to nerve cells, but are slow in speed.
-
While nerve signals become active in milliseconds, skin cells leave pulse in 1 to 2 seconds.
-
Researchers Sun-Min U did not recognize these slow signals earlier, as their software was made only to record sharp nerve signals. Later, these signals were successfully recorded when the settings changed.
What is the effect of these signals?
These electric signals remain active for about 5 hours. Scientists believe that it indicates the surrounding cells that there is damage to somewhere and the process of repair has to be started.
According to Minho of the University of California, Davis, it takes several days or weeks for tissues such as skin to recover, so slow and long signal is suitable for this process.
What next?
This discovery challenges the notion that only biochemical and mechanical signals are important in healing the wound. It is now becoming clear that the electric field also plays a big role in tissue repair.
The purpose of future research is to know how these slow electric pulse 3D works in tissue structures and how to communicate with other cells. This can help in better understanding the complex process of healing wounds.
This research is not only important from the point of view of science, but it can also open new treatment avenues in medical science, especially for patients whose wounds do not heal quickly.
