Used in battlefields for up to 5 years
According to foreign media reports on July 11th, American scientists have successfully developed “artificial blood†and can be used to treat US soldiers wounded on the battlefield as soon as possible within five years.
They use genetic engineering techniques to extract cells from the umbilical cord and use machines to simulate bone marrow hematopoietic mechanisms to produce a large number of available red blood cells, thereby creating artificial blood. The project, called "blood grafting," was initiated in 2008 by the Defense Advanced Research Projects Agency, a research institute under the Pentagon, and is aimed at hematopoiesis to treat American soldiers on remote battlefields. Arteriocyte, which received $1.95 million in research funding for the "artificial blood" project, has sent its first O-negative blood samples for identification to the US Food and Drug Administration.
Human hematopoiesis is generated by a process called "grafting," which is generated by hematopoietic cells taken from the umbilical cord. The term "grafting" refers to the use of transgenic plants or animals to make a large amount of available material. An umbilical cord can eventually be converted to about 20 units of usable blood. On the battlefield, each wounded soldier needs an average of 6 units of blood during treatment. Arteriocyte claims that the function of blood cells made using this technology is “the same as red blood cells in healthy human circulation.â€
In addition to meeting the needs of the military, artificial blood may also help the hospital in the face of blood shortage. Arteriocyte's artificial blood is O-negative blood, which is also the most urgent blood type because it can be used to treat a variety of patients regardless of their blood type. (Yang Xiaowen)
