Scientists make a “human-mouse chimera” that is 4% of humans



Researchers have created an embryo containing both human and mouse cells in the great advancement of genetically modified organisms.

The hybrid embryo, called the human-animal chimera, was grown by a team at Buffalo State University in New York and the Roswell Park Cancer Center.

The mouse embryo contains 4% human cells – a far higher proportion than has ever been achieved.


“It was not possible to generate naive people [stem cells] which contribute significantly to mouse embryos̵

“The generation of chimeras, competent naive [stem cells] unites some common features of naivety [stem cells] in mammals and may allow application as a generation of human organs in animals. “

The experiment involved human blood cells and eye cells, proving that it is possible to generate mature human cells at a much faster rate than is possible in a human embryo.

This can have significant implications for the treatment of human diseases, including Covid-19 coronavirus, as it allows cells, tissues or organs to be grown for research purposes.

The researchers injected human stem cells into the mouse embryo and allowed them to grow for two weeks. When they analyzed the embryo, they found human cells in the liver, brain, eyes, heart, blood and bone marrow of the mouse.

The researchers did not gestate further for the embryo, although there have been previous incidents in which researchers have produced chimeric hybrids outside the fetal stage.

In 1984, scientists created a hybrid of sheep and goats that survived into adulthood. Most recently, scientists in China created two chimeras from monkey pigs, but they survived only a few weeks after birth.

The study was published in the journal Scientific progress,,
