Research shows that, at least in animals, it is possible to reproduce the human ear in full size.

Researchers at Massachusetts General Hospital in Boston (USA), presented a complete and adult human ear, with the flexibility of a real ear. Scientists say they are close to creating the body from the patient's own cells.

The research used living tissue of cows and sheep that developed in a wire frame titanium flexible 3D format of a real human ear.

Then the ear was implanted in a mouse model with suppressed immune system allowing its development. We have created the first human ear in actual size from mouse model, keeping the shape of the ear after 12 weeks of growth, and mimic the natural flexibility of cartilage, Cervantes said Thomas, who led the study.

The new work shows that, at least in animals, it is possible to reproduce the human ear in full size. "This research is a significant step in the preparation of these types of fabrics for human clinical trials. Believe that these early human trials can be conducted in five years, adds the researcher.

The aim of the study conducted in the United States is creating artificial ears to help people who are born with malformed or pass through accidents or traumas.
