USA TODAY Like a scene out of a sci-fi movie, scientists have created part-human, part-monkey embryos in a bid to find new ways to make human tissues and organs for replacement therapies. In a report released Thursday in the journal Cell, scientists announced they successfully injected human stem cells into monkey embryos. It might "constitute a promising strategy for various regenerative medicine applications, including the generation of organs and tissues for transplantation." Jun Wu, assistant professor at the University of Texas Southwestern, began in 2013 working on a study involvin...

Proponents say chimera experiments could lead to a new source of transplant organs. An image from a timelapse of the monkey-human chimera Cell Monkey embryos containing human cells have been developed in a laboratory, a study by a global team of researchers confirms. The development sparks new debate on the ethics of experiments on "chimera" embryos, whose cells come from two different species. In the new study, the researchers, led by Prof Juan Carlos Izpisua Belmonte from the Salk Institute in the US, detail their experiments with cells from a long-tailed macaque and a human. They reveal t...

Credit: Salk Institute LA JOLLA--(April 15, 2021) The ability to grow the cells of one species within an organism of a different species offers scientists a powerful tool for research and medicine. It's an approach that could advance our understanding of early human development, disease onset and progression and aging; provide innovative platforms for drug evaluation; and address the critical need for transplantable organs. Yet developing such capabilities has been a formidable challenge. Researchers led by Salk Professor Juan Carlos Izpisua Belmonte have now come one step closer toward this ...

Scientists used stem cells to create a hybrid human-monkey embryo Chinese researchers have successfully created chimeric embryos by combining human stem cells and monkey blastocysts, a groundbreaking advance with both practical and ethical implications for the future of medicine.

International team creates first chimeric human-monkey embryos Image of one of the chimeric human-monkey embryos. Salk Institute for Biological Studies A team of scientists from the U.S., China, and Spain reported Thursday they have created the first embryos that were part human and part monkey and kept them alive for up to 20 days in laboratory dishes. The ethically controversial creation of chimeras — containing cells from multiple species — is part of a drive to make experimental models to help scientists better understand early development, devise new treatments for h...
