医生用3D打印机移植人耳细胞

Doctors Transplant Ear of Human Cells, Made by 3-D Printer

A 20-year-old woman who was born with a small and misshapen right ear has received a 3-D printed ear implant made from her own cells, the manufacturer announced on Thursday. Independent experts said that the transplant, part of the first clinical trial of a successful medical application of this technology, was a stunning advance in the field of tissue engineering.

制造商于周四宣布,一名出生时右耳小而畸形的20岁女性接受了由自己细胞制成的3D打印耳朵植入物。独立专家表示,这项移植是该技术成功医学应用的首次临床试验的一部分,是组织工程领域的一个惊人进步。

The new ear was printed in a shape that precisely matched the woman’s left ear, according to 3DBio Therapeutics, a regenerative medicine company based in Queens. The new ear, transplanted in March, will continue to regenerate cartilage tissue, giving it the look and feel of a natural ear, the company said.

据位于皇后区的再生医学公司3DBio Therapeutics介绍,这种新耳朵的形状与这位女性的左耳完全匹配。该公司表示,3月份移植的新耳朵将继续再生软骨组织,使其具有天然耳朵的外观和感觉。

“It’s definitely a big deal,” said Adam Feinberg, a professor of biomedical engineering and materials science and engineering at Carnegie Mellon University. Dr. Feinberg, who is not affiliated with 3DBio, is a co-founder of FluidForm, a regenerative medicine company that also uses 3-D printing. “It shows this technology is not an ‘if’ anymore, but a ‘when,’” he said.

卡内基梅隆大学生物医学工程和材料科学与工程教授亚当·范伯格说:“这绝对是一件大事。”。范伯格博士不是3DBio的附属公司,他是FluidForm的联合创始人,FluidForm是一家再生医学公司,也使用3D打印。他说:“这表明这项技术不再是‘如果’,而是‘何时’。”。
