The secret to make artificial skin may lie in spider silk. The yarn spun by the animal known as the world's strongest natural materials. Since 2,000 years ago, spider nets have also been used to prevent infection, stop bleeding, heal wounds, and function as artificial ligaments.
Now a number of German scientists to try to make artificial skin from silk spider. Transplantation of skin is vital in treating burn victims or patients who have chronic wounds, such as abrasions caused by persistent lying. In the United States, the number of patients with such wounds, reaching 6.5 million people and cost U.S. $ 25 billion per year.
German researchers studied the use of artificial skin as a skin substitute graft usually taken from the patient's body. Ideally the skin graft made of materials that can be taken into the body, strong and can be a skin cell growth medium and can unravel when new skin grows.
"A variety of materials studied so far are not strong enough to face any task," said Hanna Wendt engineering expert at the Medical School Hannover, Germany.
Strength and elasticity of spider silk is an important factor for transferring various types of implants. Unlike the silk from silkworms, spider thread does not trigger the body's rejection.
Wendt and his team have red spider silk spinning webs giant of the genus Nephila, which spun out and taken directly from the silk gland. They establish the mesh of the silk on a steel frame.
Human skin cells are placed in the mold that thrives, supplied with nutrition, warmth, and enough air. They were able to grow two types of skin cells, keratinocytes and fibroblasts, into the epidermis, the outer skin, and dermis, the layer of living tissue containing blood vessels.
