Plasma future or extracted from transgenic rice

The hospital's "blood shortage" reported from time to time in newspapers. However, the latest research by scientists shows that the plasma needed for blood transfusion may be "planted" in rice fields in the future. Scientists have successfully transformed rice genes to allow rice to make a key protein in human blood, and it is hopeful to use rice to supply human serum. The research results were published in the recent "American Academy of Sciences".
In hospitals, donated blood is divided into three components, namely red blood cells, platelets and plasma. The main component of plasma is a protein called human serum albumin, which is mainly used to supply blood to injured or patients with excessive blood loss.
Human serum albumin is mostly extracted from plasma, and this mode of production is not only limited by plasma supply, but also has a high risk of carrying viral transmission.
Scientists from Wuhan University in China, the National Research Council of Canada, and the State University of New York at Albany have teamed up to make this breakthrough. The reconstructed rice can produce a protein containing human genes that can be used to treat burned wounded people and to provide blood to wounded people who have lost too much blood.
Scientists say that this GM rice will provide hospitals with a large amount of safe human serum albumin. Yang Daichang, a professor of life sciences at Wuhan University, said: “Human serum albumin is an important protein. The global demand for this protein is more than 500 tons per year. The transgenic rice seeds can be produced in a safe and economical non-animal way. Ingredients."
The team is also studying the transformation of rice genes to produce insulin-like proteins. Insulin treats diabetes. Murphy, a cardiologist at the Royal Bristol Hospital in Bristol, UK, pointed out that this research breakthrough is expected to have a revolutionary impact on medical blood supply. He said: "This is a groundbreaking achievement. However, they have so far only verified the results on mice. The real test is to prove that it is safe for humans."
