An animal chimera is a single organism that is composed of two or more different populations of genetically distinct cells that originated from different zygotes involved in sexual reproduction. If the different cells have emerged from the same zygote, the organism is called a mosaic. Innate chimeras are formed from at least four parent cells (two fertilised eggs or early embryos fused together). … WebMar 26, 2015 · Introduction: Chimeric mice with humanized livers were recently established by transplanting human hepatocytes.
