Tracking germinal center B cells expressing germ-line immunoglobulin gamma1 transcripts by conditional gene targeting.
Germinal centers (GCs) represent the main sites for the generation of high-affinity, class-switched antibodies during T cell-dependent antibody responses. To study gene function specifically in GC B cells, we generated Cgamma1-cre mice in which the expression of Cre recombinase is induced by transcription of the Ig gamma1 constant region gene segment (Cgamma1). In these mice, Cre-mediated recom...
متن کاملLinker histone H1M transcripts mark the developing germ line in zebrafish
Maternally synthesised factors contribute to the establishment of the germ cell lineage in lower vertebrates. In zebrafish, germ-soma segregation appears to be completed by the late blastula stage of development. To search for new germ cell factors in the zebrafish, we have used subtractive cDNA cloning. Here we report that linker histone H1M transcripts mark the germ line from the early gastru...
متن کاملGerm Line Sex Determination
Zygotically contributed ovo gene product is required for the survival of female germ cells in Drosophila melanogaster. Trans-allelic combinations of weak and dominant ovo mutations (ovoD) result in viable germ cells that appear to be partially transformed from female to male sexual identity. The O V O ” ~ mutation is partially suppressed by many Sex-lethal alleles that affect the soma, while th...

متن کاملSpecification of the germ line.
In C. elegans, the germ line is set apart from the soma early in embryogenesis. Several important themes have emerged in specifying and guiding the development of the nascent germ line. At early stages, the germline blastomeres are maintained in a transcriptionally silent state by the transcriptional repressor PIE-1. When this silencing is lifted, it is postulated that correct patterns of germl...
