Scientists from Bristol University in the UK say they have found a to mass produce blood that would be for who need it in . For a number of years, they have been able to produce red blood cells in a . However, the process to do that was very slow and they could not produce a of blood. The new means scientists can make an "unlimited supply" of blood. Researcher Dr Jan Frayne said: "Previous to producing red blood cells have relied on various sources of stem cells which can only presently produce very quantities." She added: "We have demonstrated a feasible way to sustainably manufacture red cells for clinical ."

Professor David Anstee, another of the , told the BBC that his team has found a way to mass produce blood, but they now need the to actually do this on a scale. He said: "There is a bioengineering challenge. To produce that much [blood] is quite a ….The next phase of our work is to look at methods of [producing ]." He told reporters that to begin with, they would produce only types of blood, as these can be difficult to find with blood donation sources. He said: "The first therapeutic use of a cultured red cell product is to be for patients with rare blood , because suitable conventional red blood cell can be difficult to source."
