New bioreactor turns stem cells into an immune-cell factory, producing 40 million human macrophages per week
Apr 2026, phys.org
Researchers at Hannover Medical School (MHH) have developed a method for the efficient production of human immune cells, such as macrophages, in medium-sized bioreactors.
"Medium-sized", for now
