‘Blood that has been grown in a laboratory has been put into people in a world-first clinical trial, UK researchers say.
Tiny amounts – equivalent to a couple of spoonfuls – are being tested to see how it performs inside the body.
The bulk of blood transfusions will always rely on people regularly rolling up their sleeve to donate.
This is how it works:
They start with a normal donation of a pint of blood (around 470ml)
Magnetic beads are used to fish out flexible stem cells that are capable of becoming a red blood cell
These stem cells are encouraged to grow in large numbers in the labs
And are then guided to become red blood cells’
