For people with rare blood types, though, it can be near impossible to find compatible donors, making blood-related health issues far more dangerous. An initiative in the UK could present a viable solution with lab-grown blood.
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.
