科学家们从人体皮肤细胞中培育出“纱线”，这样他们就可以把人缝上
A team of researchers at the French National Institute of Health and Medical Research in Bordeaux have grown yarn from human skin cells that they call a "human textile" - and they say it could be used by surgeons to close wounds or assemble implantable skin grafts.
位于波尔多的法国国家健康与医学研究所的一组研究人员已经从人体皮肤细胞中培育出了纱线，他们称之为“人体纺织品”——他们说，外科医生可以用它来缝合伤口或组装植皮。
These human textiles offer a unique level of biocompatibility and represent a new generation of completely biological tissue-engineered products, the researchers wrote in a paper published in the journal Acta Biomaterialia.
研究人员在发表于《生物材料学报》(Acta Biomaterialia)的论文中写道:“这些人体纺织品提供了独特的生物相容性，代表了新一代全生物组织产品。”
The key advantage of the gruesome yarn is that unlike conventional synthetic surgical materials, the material doesn't trigger an immune response that can complicate the healing process, according to New Scientist.
据《新科学家》杂志报道，这种可怕的纱线的主要优势在于，与传统的合成外科材料不同，这种材料不会引发免疫反应，从而使愈合过程复杂化。
To create it, according to the magazine, the researchers cut sheets of human skin cells into long strips - and then "wove" them into a yarn-like material that can be fabricated into a variety of shapes.
据该杂志报道，为了制造这种材料，研究人员将人体皮肤细胞切成长条，然后将其“编织”成类似纱线的材料，可以制成各种形状。
We can sew pouches, create tubes, valves and perforated membranes, lead researcher Nicholas L'Heureux told New Scientist.
首席研究员Nicholas L'Heureux告诉《新科学家》杂志:“我们可以缝袋子，制造管道、阀门和穿孔膜。”
With the yarn, any textile approach is feasible: knitting, braiding, weaving, even crocheting.
“有了纱线，任何纺织方法都是可行的:编织、编结，甚至钩针。”
So far, the researchers have used the special yarn to stitch a rat's wounds and help it fully heal over two weeks. They even created a skin graft, using a custom-made loom, to seal a sheep's artery and stop it from leaking.
到目前为止，研究人员已经使用这种特殊的纱线来缝合老鼠的伤口，并帮助它在两周内完全愈合。他们甚至用特制的织布机做了一个皮肤移植，来缝住羊的动脉，防止它渗漏。
The work builds on prior research by the same team in which they produced sheets of biomaterial and rolled them into artificial blood vessels.
这项工作建立在他们之前的研究基础之前。在之前的研究中，他们制作了生物材料薄片，并将其制成人造血管。
