Chinese scientists have created an imaginary monkey

A team of scientists from China announced the world’s first birth of a monkey whose cells come from two genetically different embryos of the same species. Scientists have previously conducted similar studies in mice, but so far they have not been able to obtain chimeras in other species, especially primates.

The results and description of the research were published in the journal Cell (DOI: 10.1016/j.cell.2023.10.005).

Chimeric macaque

Chimeras are organisms created from genetically different cells from at least two individuals. Chimerism can occur within species naturally, including in humans, although it is very rare. The monkeys used in the study were crab-eating macaques (Macaca fascicle), primates commonly used in biomedical research.
