If successful, scientists could increase reserves of extremely rare blood types.
of blood grown entirely within a laboratory setting—a world’s first. About four months later, the test subjects will also receive a similar injection of donated, naturally-developed blood to compare. If the patients’ bodies don’t reject the “artificial” donation, it could be an absolute game changer for increasing supplies of previously ultra-rare blood types, and may even one day enable smaller and less frequent transfusions.
To grow the artificial blood, researchers first use magnetic beads to isolate and remove stem cells capable of becoming red blood cells from a normal, single-pint donation of blood. These stem cells are then cultivated to grow in massive numbers before being “guided” to become red blood cells. According to the, the process requires about three weeks and a starting pool of half a million stem cells in order to result in 50red blood cells.
Researchers hope to test out the new process on at least 10 volunteers before moving on to further studies. Although roadblocks still remain in terms of cost and stem cell viability times, just the ability to create blood within an artificial setting could easily have huge ramifications for the medical community.
