作者介绍了克隆的概念和目前动物克隆技术的现状、研究进展及与其有关的社会问题。

This article introduces the conception of Clone and the animals Clone technique situation , the study progresses and problems .

当人们将外源基因转染入哺乳动物细胞以后，总是希望外源基因能高效表达，并通过转基因动物克隆技术制作转基因动物，使其要求导入的外源基因在动物个体高水平表达所需要的新性状。

We always hope that the foreign genes could be highly expressed in mammalian cells and individuals when foreign genes are transfected into mammalian cells and the transgenic animals are made .

但与体内胚胎相比，体外胚胎质量一直是困扰胚胎体外生产的主要问题，这严重影响了体外受精和动物克隆技术的实际应用。

However , compared with in vivo , the quality of embryo in vitro was very unstable in vitro embryo production and affected the practice of fertilization in vitro and animal cloning .
