RAG-2-deficient blastocyst complementation: an assay of gene function in lymphocyte development.

Abstract excerpt

We describe a system to evaluate the function of lymphocyte-specific and generally expressed genes in the differentiation and/or function of lymphocytes. RAG-2 (recombination-activating gene 2)-deficient mice have no mature B and T lymphocytes due to the inability to initiate VDJ recombination. Blastocysts from RAG-2-deficient mice generate animals with no mature B and T cells following implantation into foster...
