UK researchers have begun giving lab-made blood to healthy volunteers in an unprecedented trial to provide treatment solutions for people dependent on a regular blood supply or with rare blood types.
The research project combines teams from the universities of Bristol, Cambridge, London and the British Health Service (NHS) blood and donation unit and focuses on red blood cells that carry oxygen from the lungs to the rest of the body, according to the BBC.
The trial began on two volunteers who received small amounts of artificial blood and plans to expand them over the coming months to at least 10 healthy people who will receive donations of 5 to 10 ml at least four months apart. One of the normal blood and the other blood is grown in the laboratory.
Artificial blood is labeled with a radioactive substance, which is often used in medical procedures so that scientists can see how long it stays in the body, and is expected to be more potent than usual.
Normally, red blood cells last for about 120 days before they change, and donated blood contains a mixture of young and old red blood cells, while scientists believe that artificial blood should last longer because It has recently been made in the laboratory.
According to professors from the University of Bristol involved in this unprecedented trial, the goal is to be able to manufacture certain rare blood groups in the laboratory and also meet the demand for routine blood transfusions that some people need to treat specific pathologies.
