germ layer meaning in English
胚层。
Examples
- Embryonic stem ( es ) cell lines isolated from primitive embryonic cells are highly undifferentiated and totipotent cells . in vitro , es cells can spontaneously differentiate into embryoid bodies ( ebs ) containing derivatives of three germ layers
胚胎干细胞( embryonicstemcell ， escell )系是从早期胚胎细胞分离培养而建立的高度未分化的具有全能性的细胞系。 - Part 1 : the culture and identification of es - d3 cells and the study of the efficiency of eb formation from es cells when grown on mef feeder layer in es culture medium or cultured in es culture medium supplemented with lif 1000u / ml , es - d3 cells being used in our experiments formed normal clones , expressed akp and kept their normal karyotype over many passages . the in vitro and in vivo differentiation experiments showed that es - d3 cells could differentiate into variety of cell types derived from three primary germ layers
结果显示： eso3细胞在小鼠胚胎成纤维细胞上和或含白血病抑制因于亿f ）的es细胞培养液中形成典型的胚胎干细胞克隆，碱性磷酸酶染色结果为强阳性，具有正常二倍体核型以及具有在体内外分化为三个胚层来源的组织细胞的潜能，而且具有形成种系嵌合动物的能力。 - As a member of this superfamily , human acidic fibroblast growth factor ( afgf or fgf1 ) , expressed by a variety of cells from all three germ layers , shows great potential for clinical applications for therapy of a variety of diseases , such as parkinson ' s disease , spinal cord contusion injury , neural regeneration in reimplantation of broken - off finger , brain ischemia , renal ischemia , myocardial infarction , occlusive vascularitis , retinal ischemia , gastric ulcer and nonhealing wound and so on
人类酸性成纤维细胞生长因子( afgf ， fgf - 1 )是成纤维细胞生长因子超家族成员。来自于三个胚层的多种细胞都可以表达afgf 。 afgf在治疗帕金森综合症、急性脊柱扭曲性损伤、断指中神经功能重建、脑缺血、肾缺血、心肌梗塞、闭塞性脉管炎、视网膜缺血、胃溃疡及难愈合性伤口等多种临床应用方面具有巨大潜力。
