Finally science also found a way to heal without leaving a scar

So, the uneasiness of the sisters when unfortunately scratching is already solved.

If statistics, perhaps almost everyone in this world is . scarred. Whether it's a car crash, sports or . bitten by a dog, scars still represent painful memories that few people want to remember.

Now with scars already available, you only have beauty salons to remove them. But there are new wounds, leave the science to worry. Because recently, experts have found a way to recover open wounds without scarring.

Who doesn't have one of these two .

"We can control the process of restoring wounds, helping to heal the skin thanks to self-regeneration , instead of scar tissue," said George Cotsarelis, dean of the Department of Dermatology at the University of Pennsylvania.

In fact, the injury without scarring what is supposed to be impossible for animals. That's because scar tissue does not contain fat, nor does it contain follicular cells, causing the area of ​​the injured area to have different colors and properties.

"The secret is that the hair follicles will be restored first. They will give a signal to the body to store fat on the wound, through which the skin will be closed without scarring, " Cotsarelis said.

More specifically, the skin can repair itself by pushing the fat cells (adipocyte) wound, forming our innate skin. But at the same time, scar tissue also appeared. They do not contain fat, but only myofibroblast cells - or fibroblast cells.

Compare scar tissue without fat (left) and contain fat (right).

This process is like the aging process. As you age, fat cells gradually disappear, causing the skin to become dull, different from youthful skin.

However, the experts had a great discovery. They realized that the fibrous cells could turn into fat cells, ie during the recovery process, the scar tissue would be transferred to the process of self-replicating skin. This ability is only found in fish and amphibians.

"The results of the study open up a new direction, suggesting the hope of impacting self-replicating tissues instead of scar formation," said Maksim Plikus, a researcher at the University of California, Irvine.

Some previous studies have shown that the recovery process of fat cells and hair follicles can be isolated, but not independent. Hair follicles always recover first.

If using this protein during wound healing, the skin can be closed without scarring.

Suspecting that the relationship between these two things is reciprocal, experts have tried to stimulate hair follicle cells on an injured mouse. As a result, the skin of the mouse leaves no scars. The same thing happens when testing on human skin.

Experts said that hair follicles when stimulated will emit signals in the form of morphological proteins (BMP) . It is this protein that can turn raw fiber cells into fat. And if you use this protein during wound healing, the skin can be closed without scarring.

According to Cotsarelis: "Fibroblasts are thought to be unable to turn into other cells. But this study is possible."

However, Cotsarelis also pointed out that new research is at a test level. It is true that the human skin and mouse have been shown to be effective, but the human skin here is only a laboratory sample. Obviously stimulating cells in the body hair follicles is much harder.

However, if future experiments find a way to control BMP protein, it will be a breakthrough for the cosmetology industry in the world.

The study is published in the journal Science.
