Banked blood grows stiffer with age, study finds

5 septiembre 2014

It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body, says a new study. Using advanced optical techniques, the researchers measured the stiffness of the membrane surrounding red blood cells over time. They found that, even though the cells retain their shape and hemoglobin content, the membranes get stiffer, which steadily decreases the cells’ functionality.
