‘Yarn’ grown from human skin cells can be used to sew wounds
By joining really 'bio' material with a textile-based collection, this unique tissue is extremely versatile. It can produce a variety of durable human textiles that can be easily blended in the human body.
Open wounds cause half of all leg amputations and can be life-threatening. Researchers have now developed a printer where the ink is the patient's own cells.
Yarn is usually spun from textiles such as wool, silk, cotton, or synthetic fibers.
But now a team of scientists at the French National Institute of Health and Medical Research in Bordeaux has created what they call a ‘human textile’, which is yarn grown from human skin cells.
The purpose of the human yarn is that it should be used by surgeons to close wounds or knits, crochet and weave unique designs for skin grafts.
The study has recently been published in the scientific journal Acta Biomateriala.
“These human textiles offer a unique level of biocompatibility (suitable for human biology, ed.) And represent a new generation of completely biological tissue-engineered products,” researchers write according to futurism.com.
Conventional synthetic surgical materials, for example, stitches, can trigger an immune response that can complicate the healing process. The ‘human textile’ cannot claims futurism.com.
According to the journal, scientists created the yarn by cutting long strips of human skin cells, which they then ‘wove’ into a yarn-like material.
“We can sew bags, create pipes, valves, and perforated membranes,” Nicholas L’Heureux, the lead scientist in the study, told the New Scientist medium.
So far, the special yarn has not been tested on humans. But the researchers used it to sew a rat’s wound, which helped the wound heal within two weeks.
The researchers have also tried to create a skin graft using a custom-made tissue. This one they used to seal a sheep blood vein, which prevented it from leaking.
