Cytoplasmic hybrid

from Wikipedia, the free encyclopedia

A cytoplasmic hybrid or abbreviated Zybrid ( English Cybrid ) is a living cell , its nucleus removed and replaced with the nucleus of another (animal) nature has been replaced (by somatic cell nuclear transfer ). There is therefore a hybridization at the cellular level, which creates a chimera . The chromosomal and cytoplasmic hereditary material (the Barr bodies ) come from different species. The cybrid cell can be capable of multiplying. A development into an organism has not yet been observed. The process of creating cytoplasmic hybrids is bioethically controversial.

Cytoplasmic hybrids with animal cell nuclei are used to examine genetic defects in human mitochondria , among other things to examine whether they are involved in the development of certain tumors .
