,State Intervention, 1901–1904, in gene expression, the functional diversity of cell types formed is increased, but the spectrum of lineage potentials for any given progenitor cell is diminished. The processes of lineage commitment and differentiation are regulated by an array of soluble cytokines (.) and growth factors (.–.) and by intercellular interactions (.).

Creation and Use of a Cre Recombinase Transgenic Database,knockout” resulted in early embryonic lethality, which obscured the study of potential later functions. In other cases the “knockout” did not have any phenotype due to the compensation of the gene deficiency by other family members. These limitations have called for further development of the powerful gene-targeting technology (.–.).

Isolation of Embryonic Fibroblasts and Their Use in the In Vitro Characterization of Gene Function, for pups to be born. Also, if the gene modification results in lethality late (i.e., >d 12) in the fetal period, then an analysis of the “phenotype” or of gene function could still be undertaken at the cell biological or molecular level using the embryonic fibroblast cells.

train of mice for mating contribute to the genetic composition of the targeted mouse, whereas the strain of host embryos is only relevant in that it must be compatible with the choice of ES cells, otherwise the ability of the chimeric mice to provide germline transmission of the ES cell genome may be compromised.
