For the first time, researchers have used stem cell technology to grow huge quantities of red blood cells. This could help eliminate the need for blood donations, as blood types A, B and O have been harnessed. Now there would be no question of a shortage of blood supply in blood banks, as it can be created on demand without any limits. Red blood cells could be used instead of blood and save millions of people. The universal donor blood type O-negative could be mass-produced, which is found in small numbers of Caucasians and a minuscule number of Asians. This could also mean avoiding the transmission of viruses during blood transfusions, so the future looks bright. However, the cells need to be able to survive long enough in the human body to be useful.
