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 ...
10 Μαρ 2022 · Biology definition: A chimera is an organism that possesses genetically distinct types of cells. Chimerism (the condition) can be formed by the fusion of two early blastula stage embryos or by the reconstitution of the bone marrow in an irradiated recipient or by somatic segregation.
1 Δεκ 2016 · A chimaera is typically defined as an organism composed of a mixture of different cell populations that derive from more than one zygote. They can be formed by processes such as...
1 Σεπ 2020 · This review concerns natural human chimeras that are born with cell populations derived from more than one zygote. In earlier papers on chimeras the two terms have been used interchangeably. Human chimeras have been described for nearly 70 years by clinicians, serologists and cytogeneticists.
28 Αυγ 2018 · Chimeras are organisms composed of cells derived from two or more zygotes. Clinicians, blood group serologists, and cytogeneticists have recognized natural human chimeras for more than 60 years and molecular biologists are now able to recognize them using more sensitive and definitive tests.
The term chimera has been borrowed from Greek mythology and has a long history of use in biology and genetics. A chimera is an organism whose cells are derived from two or more zygotes. Recipients of tissue and organ transplants are artificial chimeras.
The term chimera refers to an organism or tissue of a mixture of genetically different cell populations from different individuals. They can be composed of different embryos or the grafting of tissues at different developmental stages or the adult [88,89].
