Scientists create the first embryo with combined human and non-human primate cells

  TORONTO A new study explores how scientists successfully created the first embryo made with combined human and non-human primate cells. The findings, published in the journal “Cell”, may “constitute a promising strategy for various regenerative medicine applications,” including organ and tissue generation for transplants, the study says. Led by scientists at the Salk Institute for Biological Studies in California, the study takes the “next step in chimeric organisms – organisms that contain cells from two or more species to understand a host of diseases and address the severe shortage in donor organs,” according to a release. “These chimeric approaches could be really very useful for advancing biomedical research not just at the very earliest stage of life, but also the latest stage of life,” said study lead Juan Carlos Izpisua Belmonte in the release.

Human-monkey embryo created in bid to learn how cells communicate

Researchers from the Salk Institute in California have produced what is known as monkey-human chimeras, with human stem cells - special cells that have the ability to develop into many different cell types - inserted in macaque embryos in petri dishes in the lab. However, some ethicists in the UK have raised concerns, saying this type of work poses significant ethical and legal challenges and opens Pandora s box to human-nonhuman chimeras .
