Whether it's a surgical wound, a clumsy scratch, or a trauma left by a bicycle when you were five years old, everyone with scars on their body would like to have their scars disappear. Although there are scars that have occurred, we have no way to take them, but researchers have found ways to update fresh skin into new skin instead of common scar tissue. Prior to this, it was considered impossible for mammals to want wound healing without leaving it. George Cotsarelis, director of dermatology at the University of Pennsylvania, is a research member. He said: "In essence, we can manipulate wound healing so that it can regenerate skin instead of scars. The secret to achieving this goal is to regenerate first. Hair follicles. The signal released by the hair follicles then promotes fat regeneration." If you have wondered why scar tissue looks so different from normal skin, the answer now comes because scar tissue does not contain any fat cells and hair follicles. The skin that regenerates on small wounds contains fat cells, which are like the skin you were born with, which means that the two eventually blend into one when the wound heals. However, the scar tissue is mainly composed of myofibroblasts and does not contain any fat cells at all. Therefore, it does not blend into the surrounding skin after the wound has healed, and it always looks different from the skin next to it. The same is true for aging skin - when we age, we lose our fat cells, causing discolored, deep irreversible wrinkles. But scientists have found that existing myofibroblasts can be transformed into fat cells, which predicts that when a wound heals, scar tissue can be transformed into regenerative skin. Scientists previously thought that only fish and amphibians could do this. Maksim Plikus, from the University of California, Irvine, said: "These findings suggest that we have an opportunity to influence tissue regeneration rather than wait for scar formation."
