胚胎形成的

During embryonic development, many animals form a number of temporary structures along their anterior-posterior axis-somites. Cells in somites differentiate into sclerotome, which gives rise to vertebral column, dermatome, which gives rise to dermis, and myotome, which gives rise to skeletal muscle.

脊椎动物在胚胎发育的过程中沿身体前后轴形成一定数目的暂时性结构－体节，随着胚胎的继续发育每个体节分化成为生骨区、生皮区和生肌区，继而生成各种组织。

The eccrine sweat unit is composed of three sections that are modified from the tubular structure that formed during embryogenesis as a downgrowth of surface epidermis.

小汗腺单位由三部分组成，它由胚胎形成时自表面表皮向下生长形成的基本管状结构转化而成。

Many animals form a number of temporary structures along their anterior-posterior axis during embryonic development – somites. Cells in somites differentiate to form the sclerotome, the dermotome and myotome.

脊椎动物在胚胎发育的过程中沿身体前后轴形成一定数目的暂时性结构—体节，随着胚胎的继续发育每个体节分化成为生骨节，生皮节和生肌节，继而生成各种组织。

The vertebrate embryonic structure that is located just dorsal and lateral to the neural tube; it is formed from neural plate cells that break away as the neural tube is being formed; the neural crest develops into the PNS.

脊椎动物的胚胎结构，是在神经管的背向和侧向；他是从神经板细胞形成的，如同神经管被打破而形成；神经冠发展至周边神经系统。

Endoscopic Describing the type of development of a plant embryo in which the inner cell formed by the first division of the zygote develops into the embryo, while the outer cell develops into the suspensor.

内向极性：该名词用来描述植物胚胎发育的一种形式，指受精卵第一次分裂形成的内细胞最后发育为胚胎，外细胞发育为胚柄。

Bone morphogenetic proteins, members of the TGFβ(transforming growth factor-β) superfamily, play important roles in gastrulation and neurulation during embryonic period.

骨骼型态发生蛋白质(bone morphogenetic proteins， BMPs)是转型生长因子β族(transforming growth factor-β，TGF-β)的一员，其在胚胎时期的原肠胚形成及经轴胚形成过程中扮演重要角色。

This site provides image materials on fish development, including time-lapse recordings illustrate the morphogenesis of zebrafish embryos, from early cleavage to organ rudiment formation, fish epidermal cell movies, 3-D films of zebrafish gastrulation, and much more.

该网站提供有关鱼类发育的图像材料，包括阐明斑马鱼胚胎形态发生（从早期卵裂到器官初期形成）的时间间隔录象、鱼类表皮细胞影片、斑马鱼原肠胚形成的三维影片，等等。

We generated EG4-GFP cell lines expressing enhancing green fluorescence protein which still maintained typical characteristics of pluripotent stem cells. We microinjected green cells into perivitelline of 8-cell stage embryos as well as aggregated them to 8-cell stage embryos with zona pellucida removed, to investigate developmental fate of EG4-GFP cells during formation of chimeric blastocysts.

我们建立了稳定表达绿色荧光蛋白的EG细胞系（EG4-GFP），发现该细胞仍能保持野生型的一般生长特性；通过显微注射和体外聚集得到细胞与8-细胞受体胚胎共同发育形成的嵌合胚，发现转基因细胞参与了胚胎早期发育过程中的生长与分化，大部分细胞集中于内细胞团，也有细胞分化为滋胚层细胞。

Commitment to the hematopoietic and endothelial lineages within the yolk sac results in the development of discrete structures known as blood islands.

胚胎造血实质是具有不同分化潜能的前体如成血-血管形成细胞、原始红系前体细胞和永久造血多能祖细胞等有序形成的过程。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
