Heidelberg, 26 April 2018 ? For some blood transfusion patients, it is particularly difficult to find a compatible blood donor. Growing matching blood cells in the laboratory has long been an overarching goal of scientists for these patients. Research from Ashley Toye and colleagues at the University of Bristol, UK, and NHS Blood and Transplant has brought this vision one step closer to reality. The research is published today in EMBO Molecular Medicine.
