Abstract: The present invention provides transgenic animals (e.g., transgenic porcine animals), organs, tissues, and cells derived from the transgenic animals that are particularly useful for xenotransplantation therapies. In particular, the present invention provides transgenic porcine animals, as well as organs, tissues and cells derived from the transgenic porcine animals, which lack any expression of a functional alpha 1,3 galactosyltransferase (GTKO) gene and comprise at least six transgenes under the control of at least three promoters within a single multi-gene expression vector, and further comprise at least four additional genetic modifications. Also provided are methods of making the transgenic animals (e.g., transgenic porcine animals), and methods of using the transgenic animals, organs, tissues, and cells derived from the transgenic animals for xenotransplantation therapies and treating a disease or condition.

Abstract: Disclosed are compositions derived from non-primate mammals having reduced expression of alpha 1,3 gal and their use in food products, food additives, cosmetic products, cosmetic additives, medical products, medical devices and products used in research and production of therapeutics. The compositions and methods disclosed are particularly useful to subjects diagnosed with ?-Gal Syndrome (AGS).

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.

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.

Abstract: It has been found that dendritic cells can be prepared which cannot mature. These cells can provide signal 1 to T cells but cannot provide co-stimulatory signal 2. T cells which are stimulated by the permanently immature dendritic cells therefore anergise, so the dendritic cells are tolerogenic rather than immunogenic. The cells are generally CD40?ve, CD80?ve and CD86?ve, and remain so when stimulated by inflammatory mediators such as lipopolysaccharide. The cells can be prepared conveniently by the culturing adherent embryonic stem cells in the presence of GM-CSF.
