Doctors may soon be able to ‘draw’ new bone, skin and muscle on to patients, after scientists created a pen-like device that can apply human cells directly on to seriously injured people.
The device contains stem cells and growth factors and will give surgeons greater control over where the materials are deposited.
It will also reduce the time the patient is in surgery by delivering live cells and growth factors directly to the site of injury, accelerating the regeneration of functional bone and cartilage, scientists said.
TONY EASTLEY: In a world first Melbourne researchers have rebuilt the surface of a human eye, using adult stem cells grown on a special type of contact lens.
One of the researchers is Karl Brown from the Centre for Eye Research Australia. He’s speaking with Ashley Hall.
KARL BROWN: We collected the adult stem cells from the very edge of the cornea. In the final version this could be the patient’s own eye if they have a good eye and an injured eye. Or it could be from material left over that is not used for a corneal transplant.
