There’s a difference between ‘can do’ and ‘should do’, and some people, supposedly very smart people, apparently don’t know how to determine that.
Scientists grow human-monkey chimeric embryos in lab.
April 15 (UPI) — After injecting human stem cells into primate embryos, scientists were able to grow and maintain human-monkey chimeric embryos for up to 20 days.
The international research team, including geneticists in China and the United States, detailed their breakthrough in a new paper, published Thursday in the journal Cell.
“As we are unable to conduct certain types of experiments in humans, it is essential that we have better models to more accurately study and understand human biology and disease,” senior study author Juan Carlos Izpisua Belmonte, an expert in pluripotent stem cells who operates a lab at the Salk Institute for Biological Studies in California, said in a news release. “An important goal of experimental biology is the development of model systems that allow for the study of human diseases under in vivo conditions.”
The research builds on previous successes achieved by Izpisua Belmonte and his research partners in China. The team first successfully created human-monkey chimeric embryos a few years ago, keeping them alive for only a few days.
