Scientists from the United States successfully developed a technique to create artificial blood. This research project has been done since the year 2008. Engineering is done with artificial blood pharming techniques. Artificial blood made from hematopoietic cells taken from umbilical cord and then on if using a machine that could mimic the workings of the bone marrow to produce red blood cells. Red blood cells are produced
from this method does not differ from the original red blood cells and a single umbilical cord can produce 20 units of blood.
This discovery will greatly assist someone who needs blood in critical condition. Type-O negative blood is in mass production because it is the blood type blood type is suitable for all types of patients. If this artificial blood has been in mass production and sold freely, maybe there would be no human victims bitten by a vampire because vampires now have a blood supply very many of these artificial blood.
