Artificial human ear grown in lab

Artificial human ear3US scientists say they have moved a step closer to being able to grow a complete human ear from a patient’s cells.

In a new development in tissue engineering, they have grown a human-like ear from animal tissue.

The ear has the flexibility of a real ear, say researchers at Massachusetts General Hospital in Boston.

The technique may one day be used to help people with missing or deformed outer ears, they believe.

Tissue engineering is a growing field in medical science, where substitute organs are made in the laboratory in the hope of using them to replace damaged ones.

The US research team is working on artificial living ears to help people born with malformed ears or who have lost them in accidents or trauma.

Previously the researchers had grown an artificial ear, the size of a baby’s, on a mouse.

In the latest development, published in the Journal of the Royal Society Interface, they took living tissues from cows and sheep and grew them on a flexible wire frame that has the 3D shape of a real human ear.

This was then implanted into a rat whose immune system they had suppressed enabling the ear to grow.
