The production of blood on an industrial scale could become a reality once a trial is conducted in which artificial blood made from human stem cells is tested in patients for the first time. It is the latest breakthrough in scientists’ efforts to re-engineer the body, which have already resulted in the likes of 3d-printed bones and bionic limbs.
Marc Turner, the principal researcher in the £5 million programme funded by the Wellcome Trust, told The Telegraph that his team had made red blood cells fit for clinical transfusion.
Prof Turner has devised a technique to culture red blood cells from induced pluripotent stem (iPS) cells, cells that have been taken from humans and ‘rewound’ into stem cells. Biochemical conditions similar to those in the human body are then recreated to induce the iPS cells to mature into red blood cells, of the rare universal blood type O.
“Although similar research has been conducted elsewhere, this is the first time anybody has manufactured blood to the appropriate quality and safety standards for transfusion into a human being,” said Prof Turner.
There are plans in place for the trial to be concluded by late 2016 or early 2017, he said. It will most likely involve the treatment of three patients with Thalassaemia, a blood disorder requiring regular transfusions. The behaviour of the manufactured blood cells will then be monitored.
