Stem cells: International team of researchers creates 132 human-monkey embryos in China | USA

A team of researchers led by the Spanish scientist Juan Carlos Izpisúa has created 132 human-monkey embryos in a laboratory in China, in a controversial experiment first revealed by EL PAÍS in the summer of 2019 and now officially published in detail. Three of the embryos, which grew to contain up to 10,000 cells, developed for 19 days outside the uterus, at which point the researchers interrupted the study, they said in an article published by the scientific journal Cell on April 15.

Now, a team led by researchers from Brigham and Women s Hospital, has shown that a specific astrocyte sub-population can do the opposite, instead serving a protective, anti-inflammatory function within the brain based on signals regulated by the bacteria that reside in the gut. Findings on the new anti-inflammation pathway are published in
