First human patients receive transfusions of lab-grown blood cells
Lab-grown blood cells have reached a genuine turning point: manufactured red blood cells grown from stem cells have been safely transfused into human patients for the first time. What makes these cells special is their freshness — unlike donated blood, every lab-grown cell is the same age, meaning they should last closer to the full 120-day lifespan and reduce repeat transfusions. Early participants completed the process with no adverse effects. For millions worldwide living with blood disorders or rare blood types, this science crossing into human trials is the kind of progress that quietly changes everything.
