The study, funded by the British Heart Foundation (BHF), Medical Research Council (MRC) and Wellcome Trust, outlines a way for scientists to get the cells they need to make induced pluripotent stem (iPS) cells (3) from a routine blood sample. Previously scientists have struggled to find an appropriate type of cell in the blood that can be turned into a stem cell, and often make iPS cells from skin or other tissues, which can require a surgical procedure, like a biopsy.
Dr Amer Rana and his colleagues at the University of Cambridge grew patients’ blood in the lab and isolated what are known as ‘late outgrowth endothelial progenitor cells’ (L-EPCs) to turn into iPS cells. The iPS cells can then be turned into any other cell in the body, including blood vessel cells or heart cells – using different cocktails of chemicals. Scientists use these cells to study disease, and ultimately hope to grow them into tissue to repair the damage caused by heart and circulatory diseases.
