The Meaning of T’sip in Qing Lawtic processes that take place during gastrulation and early organogenesis. These experiments allow the analysis of the developmental fate and the differentiation potency of cells that are allocated to different tissue lineages during postimplantation development. Results of lineage analyses using .

ual cells and in the context of a complete organism. The method of gene inactivation relies on the ability of virtually every cell type to exchange DNA sequences with a high degree of sequence similarity by homologous recombination. In general, the procedure involves the generation of a targeting co

enome and to generate mice with specific targeted gene mutations. The improvement in the quality of reagents (embryonic stem (ES) cells and media) available to the scientific community has made this technology accessible to many laboratories.

re relatively straightforward and many of the experimental procedures are standardised (.–.). A further step toward increasing the efficiency in the generation of knockout mice lies in the pooling of resources and knowledge by establishing a centralized gene-targeting facility.
