(University of California – San Francisco) UC San Francisco scientists have used the CRISPR-Cas9 gene-editing system to create the first pluripotent stem cells that are functionally ‘invisible’ to the immune system, a feat of biological engineering that, in laboratory studies, prevented rejection of stem cell transplants. Because these ‘universal’ stem cells can be manufactured more efficiently than stem cells tailor-made for each patient — the individualized approach that dominated earlier efforts — they bring the promise of regenerative medicine a step closer to reality.
