20100077494 | Ungulates with Genetically Modified Immune Systems - 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. | 03-25-2010 |
20110038841 | Multi-Transgenic Pigs for Diabetes Treatment - The present invention provides certain animals, and in particular porcine animals, tissue and cells derived from these, which lack any expression of functional alpha 1,3 galactosyltransferase (αGT) and express one or more additional transgenes which make them suitable donors for pancreatic islet xenotransplantation. Methods of treatment and prevention of diabetes using cells derived from such animals are also provided. | 02-17-2011 |
20120282226 | Tissue Products Derived From Animals Lacking Any Expression of Functional Alpha 1, 3 Galactosyltransferase - The present invention provides tissues derived from animals, which lack any expression of functional alpha 1,3 galactosyltransferase (alpha-1,3-GT). Such tissues can be used in the field of xenotransplantation, such as orthopedic reconstruction and repair, skin repair and internal tissue repair or as medical devices. | 11-08-2012 |
20140017215 | Genetically Modified Pigs for Xenotransplantation of Vascularized Xenografts and Derivatives Thereof - 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. | 01-16-2014 |

20080250517 | Methods - The production of genetically modified animals, in which the genetic modifications are engineered in somatic cells cultured in vitro by gene targeting, is described. Genetically modified cells may then used as nuclear donors to produce, inter alia, live animals. The methods described can also be used to validate loci in animal chromosomes which are suitable sites for transgene addition to cells. | 10-09-2008 |
20120090039 | Immunocompromised Ungulates - Porcine animals, tissue and organs as well as cells and cell lines derived from such animals are provided that lack functional endogenous immunoglobulin loci and are deficient in immunoglobulin expression and B-cells. These animals are useful as model systems for research and for development of new pharmaceutical and biological agents. In addition, methods are provided to prepare such animals. | 04-12-2012 |
20120255047 | Porcine Animals Lacking Any Expression of Functional Alpha 1,3 Galactosyltransferase - The present invention is a porcine animal, tissue, organ, cells and cell lines, which lack any expression of functional alpha 1,3 galactosyltransferase (alpha1,3GT). These animals, tissues, organs and cells can be used in xenotransplantation and for other medical purposes. | 10-04-2012 |
