  • 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.
