Swine Patents (Class 800/17)
  • Patent number: 12115037
    Abstract: Reserves of immortalized genetic material are stored in a bank for providing a resource (e.g., artificial gametes) for couples (e.g., same sex couples) to produce biologically-related children. The reserves provide the ability to derive sperm from induced pluripotent stem cells (iPSCs) of one partner and/or eggs from iPSCs of the other partner. For example, a biological sample is stored as iPSCs that can be used to generate an unlimited supply of genetic material (e.g., artificial gametes for conception) when needed by a user (e.g., a year or more after the sample is provided, e.g., 5 years or more after the sample is provided). Such a bank is helpful for an individual in a same sex (or infertile) couple who desires to have biological children at some point during his/her lifetime, but does not plan to have children in the immediate timeframe, for example.

  • Patent number: 11208659
    Abstract: The present disclosure relates methods and compositions useful for prevention of porcine reproductive and respiratory syndrome virus (PRRSv) in animals, including animals of the species Sus scrofa. The present teachings relate to swine wherein at least one allele of a CD163 gene has been inactivated, and to specific methods and nucleic acid sequences used in gene editing to inactivate the CD163 gene. Swine wherein both alleles of the CD163 gene are inactivated are resistant to porcine reproductive and respiratory syndrome virus (PRRSv). Elite lines comprising homozygous CD163 edited genes retain their superior properties.

    Abstract: Methods for protecting porcine fetuses from infection with Porcine Reproductive and Respiratory Syndrome Virus (PRRSV). The methods comprise breeding a female porcine animal with a male porcine animal. The female porcine animal comprises modified chromosomal sequences in both alleles of its CD163 gene, wherein the modified chromosomal sequences reduce the susceptibility of the female porcine animal to infection by PRRSV, as compared to the susceptibility to infection by PRRSV of a female porcine animal that does not comprise any modified chromosomal sequences in the alleles of its CD163 gene. The male porcine animal comprises at least one wild-type CD163 allele.

  • Publication number: 20140017215
    Abstract: The present invention provides certain donor animals, tissues and cells that are particularly useful for xenotransplantation therapies. In particular, the invention includes porcine animals, as well as tissue and cells derived from these, which lack any expression of functional alpha 1,3 galactosyltransferase (aGT) and express one or more additional transgenes which make these animals suitable donors for xenotransplantation of vascularized xenografts and derivatives thereof. Methods of treatment and using organs, tissues and cells derived from such animals are also provided.

  • Patent number: 8581021
    Abstract: The present invention relates to a genetically modified pig comprising at least one site for integration of at least one transgene. The invention also pertains to a porcine embryo, blastocyst, fetus, donor cell and/or cell nucleus, derived from said genetically modified pig. In another aspect, the invention relates to any genetically modified porcine blastocyst, wherein the genetically modified genome comprises at least one site for integration of at least one transgene.

  • Publication number: 20130298268
    Abstract: Disclosed are materials and methods for creating customizable traits in animals. In the demonstration of the principle of the subject invention, a keratin-14 specific promoter is used with, red fluorescent protein in the loxp cassette, dominant black (?G23) beta defensin 103 in the pigment cassette, and an SV40 (with intron) polyadenylation sequence. When Cre recombinase (or HTNCre) is applied to the animal's skin in a carrier base (e.g., lipid bilayers), fur is permanently genetically modified to turn black in the shape in which it was applied.

  • Publication number: 20130276157
    Abstract: Novel mutations in cytochrome P450C17 (CYP17) and cytochrome b5 (CYB5) affecting 16-androstene steroid synthesis are disclosed. The novel mutations result in alterations in production of critical intermediaries in the synthesis of 16-androstene steroids. Altering the activity of these enzymes may be useful in enhancing reducing androstenone synthesis and reducing boar taint. The identification of these novel mutations also allows for the development of transgenic pigs bearing mutations in these enzymes or for genetic screening to identify pigs on the basis of their CYP17 and/or CYB5 genotype. Pigs having these mutations may be selected and bred to produce pigs that have a lower incidence of boar taint.
