Laboratory-grown red blood cells have been transfused into people in the first such clinical trial in the world.
Two people have been given the lab-grown cells and have so far had no side effects.
"This is the first-time lab-grown blood from an allogeneic donor has been transfused and we are excited to see how well the cells perform at the end of the clinical trial," wrote co-chief investigator Ashley Toye.
At this time, the project is still in its trial phase and time is needed before its effects are proven.
"We hope our lab-grown red blood cells will last longer than those that come from blood donors," - Cedric Ghevaert, co-chief investigator.
"...patients who currently require regular long-term blood transfusions will need fewer transfusions in future, helping transform their care."
