But in 2007, scientists made a revolutionary breakthrough. Three different groups simultaneously announced that they had converted unipotent, mature skin cells back into an undifferentiated state. In other words, they had created cells that behaved like embryonic stem cells without using any embryo derived materials. These new cells, dubbed "induced pluripotent stem cells" or IPS's could then be converted into a variety of different cell types, such as pancreas, muscle or brain cells. The IPS's were created by inserting certain genes into the DNA of the adult cells.

不过，在2007年，科学家已经取得了重大突破，三个不同组织同时发表声明称：已经能将成熟皮细胞转化回心肌细胞，也就是说不通过胚胎组织就能让细胞具有胚胎干细胞的属性，能够让多种不同类型的细胞细胞如胰腺细胞，肌肉细胞或脑细胞重新转化为人造胚胎干细胞，将某种组织注入成体细胞DNA中便能产生IPS'S。

Regression of a specialized cell or tissue to a simpler, more embryonic,''.'unspecialized'.

去分化，反分化指高度分化的细胞或组织向更简单，更初期非特化的形式的退化。

Regression of a specialized cell or tissue to a simpler, more embryonic, unspecialized form.''.'Dedifferentiation'.

去分化，反分化指高度分化的细胞或组织向更简单，更初期非特化的形式的退化。

Embryonic development is one of the most important basic questions in biology. All of the multicellular organisms are developed from a single cell, zygote.

胚胎发育是生物学研究中最重要的基本问题之一，所有的多细胞生物都是由一个单细胞——受精卵发育而来。

The study, led by Benjamin Alman from the Hospital For Sick Children, Toronto, investigated the role of the beta-catenin signaling pathway, which activates T cell factor -dependent gene transcription, and which is known to have a key regulatory role in embryonic skeletal development.

这一研究的主要负责人是来自加拿大多伦多儿童医院的Benjamin Alman，他的小组主要研究了beta-catenin信号路径的作用，这一分子信号主要负责激活和T细胞因子相关的基因转录，而科学家们已经知道以上这一激活过程对于胚胎期间的骨骼形成起着关键的调控作用。

The study, led by Benjamin Alman from the Hospital For Sick Children, Toronto, inestigated the role of the β-catenin signaling pathway, which actiates T cell factor -dependent gene transcription, and which is known to hae a key regulatory role in embryonic skeletal deelopment.

这项由来自多伦多儿童医院（Hospital For Sick Children？）的Benjamin Alman领导的研究调查了β连环蛋白信号通路的作用，这条通路能激活T细胞因子依赖的基因转录，并且被发现在胚胎骨骼发育中起关键作用。

The Antiviral substance was induced from blastulae embryonic cell line of crucian carp by ultra violet inactivated grass carp reovirus.

用紫外线灭活的草鱼呼肠孤病毒诱导鲫鱼囊胚细胞能产生一种高滴度的抗病毒物质。

BACKGROUND: Embryonic stem cells develop from early blastular inner cell mass. Under proper condition, ESCs can maintain undifferentiated state in vitro, normal diploid nuclear type, and proliferative potential. In addition, ESCs possess multi-directional differentiation capacity and can differentiate into all sorts of cells of three germ layers.

背景：胚胎干细胞来源于发育早期囊胚的内细胞团，适当条件下能在体外维持未分化状态、正常二倍体核型及无限增殖能力，且具有多向分化潜能，能够发育分化成机体3个胚层的所有类型细胞。
