The products yielded a 30% increase in the risk of death and about a threefold chance of having a heart attack of for the recipients. More than 3,711 patients were tested in sixteen studies using five types of artificial blood.[7]

Scientists from the experimental arm of the Pentagon of United States began creating artificial blood to transport blood to remote areas and transfuse blood to wounded soldiers more quickly in 2010.[10] The blood is made from the hematopoietic stem cells removed from umbilical cord between the mother and fetus of humans after birth using a method called blood pharming. Pharming has been used in the past on animals and plants to create medical substances in large quantities. Each cord can produce approximately 20 units of blood or three blood transfusions. The blood is being produced for the Defense Advanced Research Projects Agency by Arteriocyte. The Food and Drug Administration has examined and approved the safety of this blood from previously submitted O-negative blood. Using this particular artificial blood will reduce the costs per unit of blood from $5,000 to equal or less than $1,000.[10] This blood will also serve as a blood donor to all blood types. Pharmed blood may be used in human trials in 2013.
