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.


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.
