Somatic and germline mosaicism in interspecific chimaeras between Mus musculus and Mus caroli.
Detailed analysis of mosaicism in interspecific chimaeras between Mus musculus and Mus caroli revealed that cells of the two species could coexist and interact normally in all tissues studied. No selection occurred against M. caroli cells during gestation of chimaeras in the M. musculus uterus, but some tissue-specific differential growth of M. musculus and M. caroli cells occurred during postn...
متن کاملInterspecific chimeras in mammals: successful production of live chimeras between Mus musculus and Mus caroli.
Live chimeras between two species of mouse, Mus musculus and Mus caroli, were produced by blastocyst injection. These chimeras were entirely similar to M. musculus in equilibrium with M. musculus chimeras in their somatic tissue organization. This is the first report of completely normal development of interspecific chimeras in mammals.
متن کاملDevelopment of interspecific hybrids of Mus.
Artificial insemination has been used to produce interspecific mouse hybrids. Mus musculus x Mus cervicolor cervicolor hybrids failed to complete more than a few cleavage divisions but both M. musculus x M. dunni and M. musculus x M. caroli hybrids completed preimplantation development. These hybrid embryos are heterozygous for various X-linked enzymes and may provide a useful genetic system fo...
متن کاملGenome-wide architecture of reproductive isolation in a naturally occurring hybrid zone between Mus musculus musculus and M. m. domesticus.
Studies of a hybrid zone between two house mouse subspecies (Mus musculus musculus and M. m. domesticus) along with studies using laboratory crosses reveal a large role for the X chromosome and multiple autosomal regions in reproductive isolation as a consequence of disrupted epistasis in hybrids. One limitation of previous work has been that most of the identified genomic regions have been lar...
متن کاملIntrinsic factors affecting apoptosis in bovine in vitro produced embryos.
The main purpose for human assisted reproductive technologies (ART) is clearly to bypass reproductive failures. This purpose is totally different from the aims in animal ART, being genetic improvement and more recently conservation of endangered species. Apoptosis or programmed cell death has been detected before implantation in in vivo as well as in vitro embryos and might contribute to lower ...
