Scientists in Romania have developed artificial
blood
made from water, salt and protein that could one day be used in humans.
Made from the protein hemerythrin extracted from sea worms, the
faux-blood has already been successfully tested on laboratory mice. If
fully developed, the
artificial blood could end blood shortages and become a universal donor in
medical emergencies.
Unlike other past
artificial blood
experiments, the blood developed researchers at Babes-Bolyai University
in Cluj-Napoca is both durable and viable. Proven to withstand chemical
and mechanical stress, the blood remains intact and usable during
transfusions. Dr. Silaghi-Dumitrescu of the research team credits
hemerythrin for this durability, a protein found to be even more
resilient than natural hemoglobin. The artificial blood could then
transport oxygen within the bloodstream and tissue until the body is
able to recover itself.
The Romanian scientists’ work builds off of research conducted by Edinburgh and
Bristol University, which created
red blood cells from bone
marrow stem cells
in 2011. With the successful acceptance of the artificial blood by lab
mice, the team hopes to extend trials to human subjects by 2015.
