The first case of transgenic goat egg cell nuclear transfer surgery in dairy goats was recently successful, and the first clone carrying the genetically modified clone Daishan goats will be born within the expected time. Experts said that a major breakthrough in this biotechnology will have a historic leap in the field of pharmaceutical production in China. The dairy goat transgenic egg cell nuclear transfer surgery was carried out in the research and development base of genetically modified mammary gland bioreactor invested by Qingdao Senxi Industrial Co., Ltd. Many well-known domestic and foreign scientists were invited to participate in the research and experiments. The genetically engineered mammary gland bioreactor for genetically modified animals uses gene engineering technology, genetically modified organism technology, animal cloning technology, bioinformatics technology, and gene mapping "targeting" technology that is currently mastered and used by only a few scientific research units in the world. The expert who performed the operation said that the significance of the operation was to use genetic "targeting" techniques to destroy the gene in a certain position in the gene chain of the original Fushan dairy goat fibroblasts and to expect some kind of treatment. The genes of the class or nutrients and hormonal pharmaceutical proteins are transplanted at this site. Then the nuclei of the fibroblasts are transplanted into the egg cells of normal Daishan dairy goats. The sheep developed from this egg cell contain the expected results. The genes. People can drink the milk of such genetically modified sheep to achieve the purpose of treating diseases; the medicinal proteins in the milk of such genetically modified sheep can be extracted through pharmaceutical means, and medicines for treating certain diseases can be obtained. Thus, genetically modified sheep carrying different target genes become human resource-rich "drug stores" for the treatment of all kinds of intractable diseases, such as viral infections, cardiovascular and cerebrovascular diseases, and hereditary hemophilia and hepatitis B and cancer. The various pharmaceutical proteins extracted therefrom have the characteristics of low cost, high biological activity, non-infection of other viruses, and no environmental pollution during the “production†process. In view of this, the successful cultivation of genetically modified dairy goats has enormous social benefits.
