Artificial blood is a blood substitute that is created in a laboratory and can be used as a replacement for human blood in medical procedures.
Japanese scientists have developed a process of using stem cells from umbilical cord blood to create red blood cells, which are then combined with a solution of oxygen-carrying proteins to produce artificial blood.
Artificial blood can be used in emergency situations where there is a shortage of donated blood, as well as for patients with rare blood types or those who have experienced severe blood loss. It also eliminates the risk of transmitting diseases through donated blood.
One potential risk is the body's immune response to the artificial blood, which could lead to rejection or adverse reactions. There is also a concern about the long-term effects of using artificial blood, as it is a relatively new technology.
No, the artificial blood created by Japanese scientists is still in the early stages of development and has not yet been approved for use in medical procedures. Further research and testing is needed before it can be used in clinical settings.
