据外媒报道,英国纽卡斯尔大学的科学家首次成功采用3D技术打印出人类眼角膜。

According to foreign media reports, human corneas have successfully been 3D printed for the first time by scientists at Newcastle University inEngland.

 

科学家通过将来自健康供体角膜的干细胞与藻盐酸(来自海藻的凝胶)和胶原蛋白混合在一起,创造出可以打印的“生物墨水”溶液。

By mixing stem cells from a healthy donor cornea with alginate, a gel derived from seaweed, and collagen, researchers managed to create a "bio-ink" solution that can be printed.

 

之后,3D打印机可以把这种生物墨水成功打印成眼角膜的同心圆状,整个过程仅需10分钟。这项研究成果发表在《实验性眼科研究》期刊上。

This bio-ink then would be successfully expelled out of the printer in concentric circles in the shape of a cornea in less than 10 minutes, according to a paper published in Experimental Eye Research.

 

据报道,3D打印的人类角膜将需要进行进一步测试,但这一技术有望在5年内投入常规使用。

The 3D printed corneas will now have to undergo further testing but it is hoped the technique could be in regular use within five years.

 

首席研究员彻-康农表示,这项研究有助于缓解全球范围内的眼角膜移植供体短缺问题。

The lead researcher Che Connon said the research could help with the worldwide shortage of corneas for transplant.
