Scientists use spider silk and silk to make artificial skin
An international team of researchers recently reported that they combine silk fibroin with silk protein to create a low-cost bio-composite that can be used as a wound dressing to promote healing and is also expected to replace natural skin for transplant operations.
This material, developed by researchers from the Royal Swedish Institute of Technology and the Guwahati campus of the Indian Institute of Technology, has shown good results in vitro experiments and is about to be carried out in animal experiments. Spider-Silk protein has high elasticity, strength and excellent biological properties. The researchers used genetically engineered Escherichia coli to produce recombinant spider-silk proteins.
The protein binds to natural substances in human skin, such as substances that promote cell bonding, growth factors, and antibacterial proteins that promote the growth of skin cells. The production cost of recombinant silk protein is high and difficult to produce, and the researchers used it as a coating, which is combined with a substrate made of silk protein. Silk protein has no biological activity, but it can produce low cost.
The resulting composite has the advantages of both, making the flake can be used as a dressing, made of porous sponge can become the framework of artificial skin.
In an in vitro experiment, the researchers published papers in the Journal of the American Chemical Society, "Applied Materials and Interfaces," which were cultured with a variety of skin cells to produce a layered tissue similar to natural skin. The difficulty of using foreign materials to promote wound healing is to prevent bacterial infection and harmful immune responses while stimulating skin cell regeneration. The researchers say the new material allows skin cells to grow, bind, and be resistant to bacteria in a natural way.
From this news, it can be seen that the silk material is very close to the skin.So our company uses natural silk to make silk scarves, which makes your skin feel very comfortable.As a qualified silk scarf manufacturer, we will grasp the quality of silk, to bring you high-quality digital printed scarf
