Researchers successfully 3D-printed human-like ears in mice

Can potentially repair damaged cartilage in other parts of the human body

05-Jun-2020

Key points from article :

Human-like ears have been grown on the backs of mice using 3D printing.

Researchers injected a “bio-ink” made of hydrogel particles and cartilage cells into mice.

Then they shone ear-shaped patterns of near-infrared light onto the ink.

This caused hydrogel particles to stick together, develop layer-by-layer into ear-shaped structures.

After a month, cartilage cells grew around the hydrogel structures.

This resembles ear cartilage structures and team reported no side-effects.

The researchers hope the new technique could be used to construct new ears.

Helpful for people born with microtia, a condition that prevents proper ear development.
