  • Publication number: 20220211018
    Abstract: The present disclosure is directed to transgenic animals (e.g., transgenic porcine animals) comprising multiple genetic modifications that advantageously render these animals suitable donors for xenotransplanation. The present disclosure extends to organs, organ fragments, tissues and cells derived from these animals and their therapeutic use. The present disclosure further extends to methods of making such animals. In certain embodiments, the transgenic animals (e.g., transgenic porcine animals) have reduced expression of the growth hormone receptor (GHR) gene or have impaired function of the GHR protein.

  • Publication number: 20220072200
    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: 11085054
    Abstract: The present invention provides ungulate animals, tissue and organs as well as cells and cell lines derived from such animals, tissue and organs, which lack expression of functional endogenous immunoglobulin loci. The present invention also provides ungulate animals, tissue and organs as well as cells and cell lines derived from such animals, tissue and organs, which express xenogenous, such as human, immunoglobulin loci. The present invention further provides ungulate, such as porcine genomic DNA sequence of porcine heavy and light chain immunogobulins. Such animals, tissues, organs and cells can be used in research and medical therapy. In addition, methods are provided to prepare such animals, organs, tissues, and cells.
