Examples of xenotransplantation in a Sentence

Recent Examples on the Web

The field of xenotransplantation, or transplanting organs across species, has made serious strides. Katherine Ellen Foley, Quartz, "These are the organs transplant patients need the most," 30 May 2019 Since the early days of xenotransplantation, researchers and surgeons have seen pigs (specifically miniature pigs) rather than primates as the best potential organ donors for humans. Joshua Mezrich, WSJ, "Losing the Humanity of Transplants," 18 Jan. 2019 Toward Custom Organs Scientists have long been dreaming of xenotransplantation—putting animal organs into people—as a possible solution to the current human organ shortage. Megan Molteni, WIRED, "The WIRED Guide to Crispr," 27 Apr. 2018 In one study, a team of researchers edited a common virus from fetal pig genomes and then bred piglets that could one day be a source for xenotransplantation to address the human organ shortage. Jessica Firger, Newsweek, "Trump, Tasty Pigs and Hurricanes: The Top Medical Stories of the Year," 13 Dec. 2017 Luhan Yang, corresponding author on the paper and co-founder and chief scientific officer of eGenesis, which is pursuing gene editing to enable xenotransplantation, said the study addresses a key safety concern. Amy Dockser Marcus, WSJ, "What Gene-Altering for Pigs and Ants Might Mean for Humans," 10 Aug. 2017 The retroviruses are dormant in pigs, but fear of transmission to humans has been a major barrier in moving forward with animal-to-human transplants, known as xenotransplantation. Amy Dockser Marcus, WSJ, "What Gene-Altering for Pigs and Ants Might Mean for Humans," 10 Aug. 2017 The technical feat has, ironically, inspired some dread among those enthusiastic about xenotransplantation, the transfer of nonhuman animal organs into people. Kelly Servick, Science | AAAS, "CRISPR slices virus genes out of pigs, but will it make organ transplants to humans safer?," 10 Aug. 2017 In addition to immune rejection, another concern about xenotransplantation is the risk of transmittingviruses and other pathogens from one species to another. Annalee Newitz, WIRED, "Science That Could Be Fiction: Xenotransplantation," 13 Apr. 2007
