【摘要】 胚胎干细胞是从早期胚胎内细胞团或原始生殖细胞分离和克隆的具有全能性的细胞。其在动物克隆转基因动物的生产、基因结构与功能的研究以及细胞分化与发育调控的研究方面具有广泛的应用 ,对胚胎干细胞的概念特性以及胚胎干细胞特性之间的关系进行了论述更多还原

【Abstract】 Embryonic stem (ES) cells are pluripotential stem cells derived from animal embryos or primordial germ cells (PGCs). The most important applications ES cell is to clone animal, to produce transgenic Animal to, understand the relationship between genes function and their structure and to study cell differentiation and development. The concept, characteristics and their relationship were discussed with in this paper.更多还原
