Targeted mutagenesis: analysis of phenotype without germ line transmission
... When ES cells are combined with tetraploid mouse embryos, fetuses and, in the best case scenario, viable offspring can be generated in which all tissues are ES derived (6, 7). This situa- tion is brought about by the ...

Differential Reactivity of Germ Line Allelic Variants of a Broadly Neutralizing HIV-1 Antibody to a gp41 Fusion Intermediate Conformation
... germ line allelic variants are capable of binding not only to the linear nominal 2F5 epitope but also to a gp41 conformation that mimics the fusion intermediate state, thus implying that the hu- man B cell ...

glp-3 Is Required for Mitosis and Meiosis in the Caenorhabditis elegans Germ Line
... Since glp3 mutants fail to progress in either mitosis or meiosis in the germ line, glp3 may be required for both types of cell cycle. Alternatively, the lack of meiosis in glp3[r] ...

A global disorder of imprinting in the human female germ line
... The contrasting behaviour of H19 and GNAS1-NESP55 in the BiCHM is noteworthy. Although both DMRs are normally pater- nally methylated, for H19 this is primary, and therefore unaffected by an oocyte defect. At NESP55, ...
