"Glowing Green: The Breakthrough of Live-Birth Chimeric Monkeys"

Chinese researchers have achieved the first live birth of a chimeric monkey, a significant breakthrough in primate research. The monkey is composed of cells derived from two genetically distinct embryos of the same species, opening new avenues in understanding stem cell pluripotency and having implications for genetic engineering and biomedical studies. The researchers established stem cell lines and injected a subset of stem cells into early monkey embryos, resulting in 12 pregnancies and six live births. The chimeric monkey exhibited stem cell-derived tissue in various organs, with contributions ranging from 21% to 92%. Future research aims to optimize the generation of chimeric monkeys and explore the mechanisms underlying embryo survival.
