Interspecific chimeras in mammals: successful production of live chimeras between Mus musculus and Mus caroli.

"Interspecific Chimeras in Mammals: Successful Production of Live Chimeras Between Mus musculus and Mus caroli" (1980), by Janet Rossant and William I. Frels

In 1980 Janet Rossant [5] and William I. Frels [6] published their paper, ?Interspecific Chimeras in Mammals: Successful Production of Live Chimeras Between Mus musculus and Mus caroli ,? in Science. Their experiment involved the first successful creation of interspecific mammalian chimeras [7]. Mammalian chimeras [8] are valuable for studying early embryonic development. However, in earlier st...

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...

Development 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...

Leptospirosis in small mammals of Iran: II: Isolation of Leptospira grippotyphosa, from Mus musculus

Reduced nucleotide variability at an androgen-binding protein locus (Abpa) in house mice: evidence for positive natural selection.

Previous work has shown that the gene for the alpha subunit of androgen-binding protein, Abpa, may be involved in premating isolation between different subspecies of the house mouse, Mus musculus. We investigated patterns of DNA sequence variation at Abpa within and between species of mice to test several predictions of a model of neutral molecular evolution. Intraspecific variation among 10 Mu...
