Cartilage grown to rebuild body parts

Patients needing surgery to reconstruct body parts such as noses and ears could soon have treatment using cartilage which has been grown in a lab.
The process involves growing someone’s cells in an incubator and then mixing them with a liquid which is 3D printed into the jelly-like shape needed.
It is then put back in an incubator to grow again until it is ready.
Researchers in Swansea hope to be among the first in the world to start using it on humans within three years.
