For the First Time, Lab-Grown Blood Is Pumped Into a Human’s Veins | Popular Science

Artificial blood may become a common reality, thanks to the first successful transfusion of lab-grown blood into a human. Luc Douay, of Pierre and Marie Curie University, Paris, extracted hematopoietic stem cells from a volunteer’s bone marrow, and encouraged these cells to grow into red blood cells with a cocktail of growth factors. Douay’s team labeled these cultured cells for tracing, and injected 10 billion of them (equalling 2 milliliters of blood) back into the marrow donor’s body.
