Imagine having an ear made out of an apple.It seems like a crazy idea from a horror movie.But it could
happen in the near future.
Canadian biophysicist Andrew Pelling used an apple to grow a human ear.He thinks fruit and vegetables can
be used to cheaply repair human body parts in the future.
Scientists have been trying to grow organs in labs to replace our old ones.But it is a hard job.For example,
liver cells can grow in a lab,but the cells still need things like blood vessels to actually work.These things have to
grow inside a scaffold called the extracellular matrix.
In the past,scientists have used man-made materials,animal parts and even dead people as scaffolds.But that
has proved to be complicated and expensive.
Pelling and his team,however,found the apple to be a cheap and easy-to-use scaffold.
They first cut an apple into the shape of an ear.Then they used a special way to take out the apple's cells and
make it a scaffold.The team then added human cells to the apple,and watched it grow.
"You can implant these scaffolds into the body,and the body will send in cells and a blood supply and
actually keep these things alive,"Pelling said during a Ted Talk speech.
The team put the apple scaffold inside a living mouse and the mouse's cells slowly took over the pieces of
apple.
Now Pelling is thinking of other fruit,plants or vegetables to use.
He says that the shape of flower petals could be perfect for repairing skin.And asparagus could fix a broken
spine.
