  • The plan, says the company, is to use the gene-editing method known as CRISPR to introduce extensive DNA modifications into pigs as a way of humanizing their organs so they won't get rejected if transferred into a person. (technologyreview.com)
  • The idea of xenotransplantation-or using animal organs to replace human ones-fell out of favor in the 1990s because of evidence that pig or baboon organs unleashed severe immune storms and would be swiftly destroyed in the human body. (technologyreview.com)
  • Recent and ongoing research suggests an alternative approach that can achieve the same goal (repair of damaged or diseased organs) without destroying human embryos. (reasons.org)
  • The chief one is hyper-acute rejection (HAR)-the rejection of pig organs by the human recipient. (reasons.org)
  • Continued development of new biotechnologies also will allow farm animals to serve as sources of both biopharmaceuticals for human medicine and organs for transplantation. (nationalacademies.org)
  • General Assembly the following year,3 and the World Medical Association's Resolution on Cloning, endorsed in 1997, have confronted the issue but lack binding legal force. (who.int)
  • There he continued his research on the cloning and genetic modification of livestock. (nottingham.ac.uk)
  • For example, genetic modification of animals may lead to technologies that reduce the major losses that occur during the first months of embryogenesis. (nationalacademies.org)
  • Cloning in biotechnology refers to processes used to create copies of DNA fragments ( molecular cloning ), cells (cell cloning), or organisms . (wikiquote.org)
  • The term applies not only to entire organisms but also to copies of molecules (such as DNA) and cells. (who.int)
  • Animals sexually derived from the fusion of gametes from two different organisms, such as mules, are considered "hybrids. (frontiersin.org)
  • To take human organ generation via BC and transplantation to the next step, we reviewed current emerging organ generation technologies and the associated efficiency of chimera formation in human cells from the standpoint of developmental biology. (frontiersin.org)
  • The activated oocytes were then transferred into the oviducts or uterine horns of recipient dogs at times appropriate to the embryos' developmental stages. (nature.com)
  • In this review, we summarize the history of interspecies chimerism in various animal models to find hints for BC application and describe the challenges and prospects of utilizing BC for human organ generation. (frontiersin.org)
