Healthy wound by artificial tissue

American scientists have created artificial tissue pieces from collagen, helping patients with burns or severe skin damage quickly recover, shorten the process of treatment and surgery.

According to Abraham Stroock, a scientist at Cornell University in the US and colleagues, the structure of a piece of artificial tissue is a coin-sized rig made of type 1 collagen, the most commonly used material. in surgery and other biomedical applications. This tissue has the effect of directly promoting healthy tissue to grow in the damaged area.

With this new tissue layer, the vascular system keeps the function of circulating blood and fluids throughout the body. When implanted, blood vessels in the affected areas will develop under the dermis, the deepest layer of skin and blood vessels.

Type 1 collagen is biocompatible and does not contain living cells, thus reducing the immune system response as well as the ability to remove transplanted tissue. It is the reaction of the recovery process of collagen with micro-channels of collagen that plays an important role in promoting healthy tissue and blood vessels rapidly developing.

Using artificial tissue in wound healing is not a new issue, since they have been used a lot in treating burns or other deep wounds.

However, in the past, the ability to promote healthy tissue development was still low due to lack of microchannels in collagen and it took a long time for the patient's body to adapt to the implanted tissue. They are also at high risk of infection and need careful care.
