Because bone marrow contains stem cells that develop into red blood cells, a person with a bone marrow transplant will have blood cells that are genetically identical to those of the donor whileother types of cells in their own bodies may remain the same, turning the recipient into a human chimera. One way that. Scientists have found it much easier to create chimeras from species that are evolutionarily close to each other, like mice and rats, or humans and monkeys. For example, the animal can end up with one organ made up entirely of cells of one genotype, and another organ completely built from cells of the other genotype. Because of this, most human chimeras do not know theyre chimeras until they have to take a DNA test for another reason. Khan F, et al.
