KUOW - Scientists Create Early Embryos That Are Part Human, Part Monkey

Using fluorescent antibody-based stains and advanced microscopy, researchers are able to visualize cells of different species origins in an early stage chimeric embryo. The red color indicates the cells of human origin.

For the first time, scientists have created embryos that are a mix of human and monkey cells.
The embryos, described Thursday in the journal Cell, were created in part to try to find new ways to produce organs for people who need transplants, says the international team of scientists who collaborated in the work. But the research raises a variety of concerns. ....

By slipping human stem cells into the embryos of other animals, we might someday grow new organs for people with faltering hearts or kidneys. In a step toward that goal, researchers have created the first embryos with a mixture of human and monkey cells. These chimeras could help scientists hone techniques for growing human tissue in species better suited for transplants, such as pigs.
The paper is a landmark in the stem cell and interspecies chimera fields,” says stem cell biologist Alejandro De Los Angeles of Yale University. The findings hint at mechanisms by which cells of one species can adjust to survive in the embryo of another, adds Daniel Garry, a stem cell biologist at the University of Minnesota (UM), Twin Cities. ....
