原肠

An embryo at the stage following the blastula, consisting of a hollow, two-layered sac of ectoderm and endoderm surrounding an archenteron that communicates with the exterior through the blastopore.

原肠胚一种囊胚之后的胚胎，含有中空、两层的外胚层和内胚层，包围着通过胚孔跟外界交流的原肠

The PGCs of Varicorhinus macrolepis first appeared in the mesoderm of early gustrula and subsequently remained in the hypoblast of the embryonic region during late gustrula and neurula stage. At the stage of muscular effect they were found in the splanchnic mesoderm and the proceeded around the gut to the dorsal mestery during hatching stage.

结果表明：泰山螭霖鱼PGCs最早出现于原肠早期；原肠晚期和神经胚期靠近卵黄囊的内胚层；肌肉效应器迁移到脏壁中胚层的肾原基附近；临出膜期到达体腔壁，随后，沿肠系膜进入两侧的生殖嵴中。

Nodal gene is a member of the TGF-β superfamily.

它在小鼠原肠期的原条形成过程中起重要作用。

The results showed that when both β-actin and GAPDH were used as internal control the MYH mRNA expression was complete consistent, and its expression was increased from the gastrula stage to larval stage, which represented the statistic significant difference at the level of 0.05 possibility. However, the level of mRNA expression during the developmental stages was instable when 18S rRNA was used as internal control gene.

研究结果表明，以β-actin和GAPDH作为内参，MYH基因mRNA表达水平完全一致，其表达量从原肠到仔鱼阶段逐次递增，仔鱼与原肠期阶段相比表达量差异显著；当采用18S rRNA作为内参时，MYH基因mRNA在发育阶段的表达量呈不稳定状态。

It is required for the formation of the primitive streak during mouse gastrulation.

它在小鼠原肠期的原条形成过程中起重要作用。

Since the altered dorsal-ventral domain was started at early gastrulation and became more obvious at the late gastrulation stage, P5 and P4 both may affect cell fate maintenance through regulating cell migration during gastrulation period.

因为cyp11a1表现下降的鱼卵是在原肠期刚要开始的时候才开始出现不正常腹部组织增大，而且随著时间的增加而更加明显，所以P5和P4可能是藉由影响原肠期的细胞移动进而去影响后来的细胞分化。

Suppression subtractive hybridization cDNA plasmid libraries were constructed between gastrula embryos and tail bud embryos in gynogenetic gibel carp.739 and 816 PCR positive clones were respectively selected to perform dot blot,and 72 dot blot positive clones and 98 dot blot positive clones were obtained from the SSH plasmid libraries specific for gastrula embryos and tail bud embryos.

构建了雌核发育银鲫原肠期胚胎和尾芽期胚胎间的抑制性差减杂交cDNA质粒文库。对原肠期739个和尾芽期816个PCR阳性克隆进行斑点杂交，得到72个原肠期和98个尾芽期斑点杂交阳性克隆。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
