Human chimera

A human chimera is a human with a subset of cells with a distinct genotype than other cells, that is, having genetic chimerism. In contrast, an individual where each cell contains genetic material from a human and an animal is called a human–animal hybrid, while an organism that contains a mixture of human and non-human cells would be a human-animal chimera.^[1]

Human chimera embryos are human embryos that have had animal cells added to them during early development. … Lastly, transgenic human embryos are human embryos that have had animal genes inserted into them early in development.
