(Medical Xpress)—Yuet Wai Kan of the University of California, San Francisco and colleagues have created HIV-resistant white blood cells by editing the genomes of induced pluripotent stem cells. The researchers inserted genes with a mutation that confers resistance to HIV into stem cells. White blood cells grown from these stem cells were HIV resistant. The research appears in the Proceedings of the National Academy of Sciences.
