These Yarns Are Grown From Human Skin Cells And They Can Be Used To Stitch Up Wounds

A research team at the French National Institute of Health and Medical Research has just announced human textile, yarn developed from human skin cells. The experts said that the invention can be used by surgeons to stitch patients up after surgeries as well as making skin grafts for implants.

According to the researchers in a paper published on the journal Acta Biomaterialia, their human textiles can give us a uniquely high level of biocompatibility and herald a new era of biological tissue engineering.

The highlight of growing yarn from human tissues is that when they are used on patients’ bodies, they will less likely to trigger reactions from the immune system, which can make healing harder.

As stated by the paper, the team cut human skin cells into sheets and then weave them together to make yarns. These materials can then be shaped as we like.

Some of the applications suggested by Nicholas L'Heureux, the lead researcher of this creation, are tubes, pouches, perforated membranes, and valves. As the material is in yarn-like shape, any weaving techniques can be used on it, be it braiding, crocheting, knitting, or weaving.

Some of the tests the researchers have done were stitching up a wounded rat and making a skin graft with a special loom. The first test’s result was the test subject healed in two weeks, while the skin graft helped a patch the leak of a sheep’s artery.

The team’s previous creation is the foundation for this one. Before this human textile, the researchers developed biomaterial sheets and turned them into blood vessels.
