  • Production of reprogrammed cells with restored potential
    Publication number: 20070032447
    Abstract: A method for treating cells and/or nuclear transfer units and/or stem cells in culture with such compounds, individually or in combinations, is described. The method results in a globally hypomethylated genome and a restoration of cell differentiation and/or developmental potential, or potentiality. In addition, a method for the in vitro production of reprogrammed cells which have had differentiation potential (totipotential, pluripotential, or multipotential) restored by demethylating the genome is described.

  • Methods for cloning mammals using remodeling factors
    Publication number: 20050149999
    Abstract: Methods and compositions are provided for remodeling nuclear donor material used in nuclear transfer procedures. By exposing donor chromatin to one or more exogenous remodeling factors, the limited ability of mammalian oocytes to remodel the chromatin of differentiated cells, including fetal and live-born somatic cells, can be increased, resulting in dramatically improved cloning efficiencies.

  • Sex- specific selection of sperm from transgenic animals
    Publication number: 20050081256
    Abstract: The present invention relates to methods and materials for pre-selecting the sex of mammalian offspring. In particular, the materials and methods described herein permit the enrichment of X- or Y-chromosome-bearing sperm in semen by introducing a transgene into a sex chromosome under control of regulatory sequences that provide for expression of the transgene in a haploid-specific manner.

  • Immune response replication in cloned animals
    Publication number: 20040055025
    Abstract: The present invention provides a method and materials for reproducing an immune response of a mammal against one or more antigens of interest. The method preferably involves cloning a founder mammal and producing an immune response in the clone that is substantially identical to the immune response of the founder animal to the antigen or antigens of interest. Accordingly, a source of valuable antibodies can be maintained despite the death or illness of the antibody producing animal.
