Scientists Have Transfused Lab-grown Blood Into Humans For The First Time

UK scientists have transfused lab-grown blood into humans for the first time. It could revolutionize treatment for people with rare blood types, especially those who need regular transfusions. Two people were injected with 1-2 teaspoons of the synthetic blood to see how how their bodies respond. So far, so good – the trial participants are fit and healthy with no reported side effects.
