Human–monkey chimeric embryos created using stem cells

Written by Heather Jones

Image credit: Weizhi Ji, Kunming University of Science and Technology Researchers in China and the USA have successfully grown chimeric embryos for up to 20 days by integrating human stem cells into primate embryos. Though this research does raise ethical concerns, it has the potential to provide new insights into developmental biology and evolution, and address the shortage in donor organs. The study has been published in Cell. The ability to grow the cells from one species within an organism of another species offers a powerful tool for medical research. The potential implications are wide and could advance our understanding...
