人體皮膚“紗線”很快就能用來縫合傷口

French researchers say they’ve grown ‘yarn’ from human skin that could be used to stitch people back up after suffering major wounds, according to a paper published in the journal Acta Biomaterialia.

據(jù)《生物材料學(xué)報》發(fā)表的一篇論文稱，法國研究人員稱，他們已經(jīng)從人類皮膚上培育出“紗線”，可以用來縫合受重傷的人。

The “human textile,” as it’s called, could one day replace standard synthetic stitches that can sometimes cause immune reactions that complicate the healing process, Science Alert reported.

據(jù)《科學(xué)警報》報道，這種“人體紡織品”有朝一日可能取代標準的人工縫線，這種人工縫線有時會引起免疫反應(yīng)，使愈合過程復(fù)雜化。

The sci-fi threads — which can be woven like a handmade sweater — may also be used for skin grafts.

這種人體紗線可以像手工毛衣一樣編織，也可以用于植皮。

“We can sew pouches, create tubes, valves and perforated membranes,” lead researcher Nicholas L’Heureux told New Scientist.

“這種人體紗線可以縫袋子，制造管子，閥門和穿孔膜。”首席研究員尼古拉斯·勒魯告訴《新科學(xué)家》。

Researchers cut sheets of human skin cells into long, yarn-like strips and have used them to successfully mend animals so far, the report said.

報告稱，研究人員將人類皮膚細胞切成細長的、像紗線一樣的條狀，迄今為止，他們已經(jīng)成功地用這些細胞修復(fù)了動物。

They stitched up a rat’s wound that healed within two weeks and created a skin graft with a custom-made loom to repair a sheep’s leaking artery.

他們縫合了一只老鼠在兩周內(nèi)愈合的傷口，并用特制的織布機做了皮膚移植，修復(fù)了一只羊漏水的動脈。

“By combining this truly ‘bio’ material with a textile-based assembly,” the team wrote in their article abstract, “this original tissue engineering approach is highly versatile and can produce a variety of strong human textiles that can be readily integrated in the body.”

“通過將這種真正的‘生物’材料與以紡織品為基礎(chǔ)的組件結(jié)合起來，”該團隊在他們的文章摘要中寫道，“這種原始的組織工程方法是高度通用的，可以生產(chǎn)多種強大的人體紡織品，很容易融入人體。”
