A British man who lost his nose to cancer is having a new nose made for him by scientists at University College London. The nose is currently being grown inside the man's arm, where it will acquire blood vessels, nerves and skin.
University College London professor Alex Seifalian explained that the new nose will look exactly the same as the old one. "His nose was a little bit bent to the left and we asked if he wanted it straight but he said no, he wanted it exactly the same," Seifalian said.
This animation illustrates how the University College London scientists created the new nose from stem cells taken from the man's cartilage.
