Cloning Animals
February 2nd, 2009 | by Ramaswami |Cloning animals technique helps the human race in protecting the rare variety of animal species. Some of the patented techniques are given below.
Patent No: 6,603,059 titled ‘Method of cloning animals’ with the abstract: The present invention relates to cloning technologies. The invention relates in part to immortalized and totipotent cells useful for cloning animals, the embryos produced from these cells using nuclear transfer techniques, animals that arise from these cells and embryos, and materials, methods, and processes for establishing such cells, embryos, and animals.
Patent No: 7,071,372 titled ‘Method for cloning animals with targetted genetic alterations by transfer of long-term cultured male or female somatic cell nuclei, comprising artificially-induced genetic alterations, to enucleated recipient cells’ with the abstract: An improved method of nuclear transfer employing long-term cultured somatic cells as the donor cells and enucleated oocytes as the recipient cells to produce dividing cybrids. Such cybrids are useful for developing viable animal’s clones when nurtured in a suitable host environment.
Patent No: 6,781,030 titled ‘Methods for cloning mammals using telophase oocytes’ with the abstract: he present invention pertains to methods for cloning animals. In particular, the invention includes methods of cloning an animal by combining a genome from an activated donor cell with an activated enucleated oocyte to thereby obtain a nuclear transfer embryo, and impregnating an animal with the nuclear transfer embryo in conditions suitable for gestation of a cloned animal. The invention further relates to methods of chemically enucleating an oocyte having a meiotic spindle apparatus by exposing the oocyte with a compound that destabilizes the meiotic spindle apparatus.
Patent No: 6,395,958 titled ‘Method of producing a polypeptide in an ungulate’ with the abstract: The present invention relates to cloning technologies. The invention relates in part to immortalized and totipotent cells useful for cloning animals, the embryos produced from these cells using nuclear transfer techniques, animals that arise from these cells and embryos, and materials, methods, and processes for establishing such cells, embryos, and animals.
Patent No: 6,011,197 titled ‘Method of cloning bovines using reprogrammed non-embryonic bovine cells’ with the abstract: The present invention relates to cloning technologies. The invention relates in part to immortalized and totipotent cells useful for cloning animals, the embryos produced from these cells using nuclear transfer techniques, animals that arise from these cells and embryos, and materials, methods, and processes for establishing such cells, embryos, and animals.
Patent No: 6,011,197 titled ‘Method of cloning bovines using reprogrammed non-embryonic bovine cells’ with the abstract: The present invention relates to cloning technologies. The invention relates in part to immortalized and totipotent cells useful for cloning animals, the embryos produced from these cells using nuclear transfer techniques, animals that arise from these cells and embryos, and materials, methods, and processes for establishing such cells, embryos, and animals.
Patent no: 5,945,577 titled ‘Cloning using donor nuclei from proliferating somatic cells’ with the abstract: An improved method of nuclear transfer involving the transplantation of donor differentiated cell nuclei into enucleated oocytes of the same species as the donor cell is provided. The resultant nuclear transfer units are useful for multiplication of genotypes and transgenic genotypes by the production of fetuses and offspring, and for production of isogenic CICM cells, including human isogenic embryonic or stem cells. Production of genetically engineered or transgenic mammalian embryos, fetuses and offspring is facilitated by the present method since the differentiated cell source of the donor nuclei can be genetically modified and clonally propagated.
