Scientists develop 'fake' genetically-engineered blood for use on the battlefield

So what's the self life for this very expensive substitute?

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.

The blood is made by using hematopoietic cells taken from umbilical cords in a process called ‘pharming’ – using genetically engineered plants or animals to create mass quantities of useful substances.
One umbilical cord can be turned into around 20 units of usable blood. A wounded soldier in the field will require an average of six units during treatment.
Blood cells produced using this method are 'functionally indistinguishable from red blood cells in healthy circulation', the company claims.
‘We’re basically mimicking bone marrow in a lab environment,' Arteriocyte boss Don Brown told Wired magazine.
