blood grown in a lab has been transfused into humans for the first time

For the first time ever, blood grown in a lab from adult stem cells was transfused into two people. The trial will be expanded to include 10 participants, with scientists comparing the lab-grown blood’s longevity to that of a traditional transfusion. The bulk of blood transfusions will always rely on people regularly rolling up their sleeve to donate. But the ultimate goal is to manufacture vital, but ultra-rare, blood groups that are hard to get hold of. [https://www.bbc.com/news/health-63513330](https://www.bbc.com/news/health-63513330)
