1st chimeric monkey born with large embryonic stem cell contribution

Nov. 9, 2023
By Anette Breindl
Investigators at the Chinese Academy of Sciences have generated a chimeric monkey by injecting an embryonic stem cell into the morula, which is an extremely early embryo consisting of 16 to 32 cells. The animal survived for only 10 days, and it is not the first live birth of a chimeric primate. But it is the first such chimera with contributions from an embryonic stem cell, and that stem cell contributed a far higher proportion of cells in the newborn than have been achieved in previous attempts at creating chimeras.
