We have to wait a few more years for human trials, but this could have a significant positive impact for military and disaster situations.
"American scientists have developed 'artificial' blood that could soon be used to treat wounded soldiers in battle.
The genetically-engineered blood is created by taking cells from umbilical cords and using a machine to mimic the way bone marrow works to produce mass quantities of usable units of red blood cells.
Known as 'blood pharming' the programme was launched in 2008 by the Pentagon's experimental arm, Darpa, to create blood to treat soldiers in far-flung battlefields.
The firm Arteriocyte, which received $1.95 million for the project, has now sent off its first shipment of O-negative blood to the food and drugs watchdog in the US, the FDA."
