Scientists in China have made an astonishing breakthrough in the field of genetic engineering, successfully creating a monkey chimera with two sets of DNA and unique fluorescent characteristics. The scientists employed pluripotent monkey stem cells that were capable of developing into any type of cell within a living organism. These stem cells were labeled with a green fluorescent protein, enabling the researchers to identify the tissues derived from them in the monkey chimera. Pluripotent stem cells labeled with a green fluorescent protein were injected into early monkey embryos, which were then implanted into female macaques. A: The researchers demonstrated that pluripotent monkey stem cells can differentiate in vivo into various tissues within a monkey’s body.
