Scientists Find Success in Creating Lab-Grown Blood

Researchers in the U.K. have achieved something of a world first: they have manufactured blood in the lab, which they’ve since administered to humans. The clinical trial will aim to test the safety and effectiveness of the lab-made blood in at least 10 healthy people. Two volunteers have already received a dose. The scientists — from the University of Cambridge, the National Health Service and the University of Bristol — are keen to find out whether their novel blood can last as long as normal red blood cells (which normally stay alive for about 120 days inside the human body) and whether there are any side effects.
