Researchers create artificial skin that can grow hair and sweat
It is a new achievement in the creation of replacement tissues that has emerged in aJapanese laboratory. A team at the RIKEN Center for Developmental Biology helpedother experts, has succeeded in creating artificial skin in the laboratory. A structure very similar to real skin, with sebaceous glands and hairs.
From skin cells of gingiva
To get there, the scientists used cells from mouse gingiva. They have updates in contact with chemical substances in order to turn them into similar cells capable of differentiating stem cells. They then used these to design a functional skin tissue.
Finally, researchers have implanted tissue obtained in mice and perfectly, it continued its development. He created three layers and structures found in normal skin. Thefabric is even managed to establish connections with the nerves and surrounding muscles, allowing a normal operation.
Fourteen days after the transplant, the team found that hair had begun to grow onartificial skin, according to the findings published in the journal Science Advances.
An obstacle overcome
Before this work, Japanese researchers had already managed to design a skin substitute. It had even been tested successfully in human patients. But the substitute wasmuch more basic. He presented only one to two layers of fabric and was devoid of structures such as hair follicles and sebaceous glands.
"Until now, the development of artificial skin has been hampered by the fact that the skin has lacked important organs, such as hair follicles and (...)
