Identification of embryonic cell lineages in histological sections of M. musculus in-equilibrium M. caroli chimaeras.
An in situ cell marker system has been developed which allows identification of Mus caroli and Mus musculus cells in interspecific chimaeras. A radioactively labelled, cloned DNA probe to M. musculus satellite DNA was hybridized in situ to sections of M. musculus and M. caroli adult tissues. Autoradiography revealed high levels of hybridization to the nuclei of M. musculus cells, but little or ...
متن کاملSomatic 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 کاملFetal adrenal capsular cells serve as progenitor cells for steroidogenic and stromal adrenocortical cell lineages in M. musculus.
The lineage relationships of fetal adrenal cells and adrenal capsular cells to the differentiated adrenal cortex are not fully understood. Existing data support a role for each cell type as a progenitor for cells of the adult cortex. This report reveals that subsets of capsular cells are descendants of fetal adrenocortical cells that once expressed Nr5a1. These fetal adrenocortical cell descend...
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 کاملRabbit M cells and dome enterocytes are distinct cell lineages.
We have studied the M cell origin and differentiation pathway in rabbit gut-associated lymphoid tissues. Micro-dissected domes and epithelium isolated by ethylene diamine tetra acetic acid detachment allowed us to view the whole epithelial surface from the bottom of crypts to the top of domes. We used monoclonal antibodies specific to the apex of either M cells or dome enterocytes, lectins, and...
