Following arrival of the post-genomics era,transgenic animals have become the most effective novel experimental model, and the application field of Transgenic mice ( Tg mice ) is becoming more and more extensive. The study of the functional genomics using Tg mice is called post-genomics as well. The in vivo study of genome and it's regulatory role has overcome the limitations and one-sidedness in the field. The technical platform for preparation of genetically engineered mice has been formed scaled up and commercialized both at home and abroad. The article here is an overview of the application, development and the status and trend of Tg mice at home and oversea.%随着后基因组时代的到来,转基因动物已成为新兴的最有效的动物实验模型,转基因小鼠应用领域越来越广泛.利用转基因小鼠,从生物整体上研究基因组的功能学,又称为后基因组学.活体研究各基因及调控作用,克服了原来此领域研究的局限性和片面性.国内外基因工程小鼠的制备已经形成了技术平台,发展规模化、商业化.现就转基因小鼠的发展、应用及转基因小鼠国内外现状和发展趋势予以综述.
