J. Warren Evans Department of Animal Science Texas A&M University College Station, Texas 77843 In the near future, improvement of domestic animals for the production of food and fiber is poised to undergo a revolution by the utilization of recent breakthroughs and advances in molecular genetics, embryo manipula tions, and gene transfer systems. Utilization of these techniques will have a wide impact on animal agriculture by improvement of production effi ciency via manipulation and control of many physiological systems. The end result will be to decrease production costs, increase food production and quality, and lower food costs. Health and well being of domestic and other animals will be improved as a result of new methods of disease diagnosis, vaccine production, and disease prevention practices. Genetic engineering also offers the possibility of utilizing animals for the development of pharmaceutical products to benefit society. Research progress will be en hanced via manipulation of the gene pool. The objectives of this Conference were to discuss the current status of animal bioengineering and to realistically assess the potential applica tions of current and future genetic technologies for the production of food and fiber to meet the needs of our hungry world, and to provide animal sci entists who may wish to utilize bioengineering in current or future re search programs with current background information regarding concepts, ap plications, and methodologies.

为了解决这个问题,张进团队在“鸡蛋”还没有受精前进行细胞核移植,这种做法从技术上看是领先的,同时从伦理道德上也相对容易被接受。具体操作过程为,医生先移除Shaban的卵子原核,再植入同被去除卵子原核的捐赠者卵子内,然后授精。张进团队以这种方法, ...
