ER took part in cell wall material deposition during endosperm cell construction. ER rounded up matrix forming endocytic vacuole. ER cisterna swelling and accumulating starch developed into amyloplast. ER took part in protein synthesis and deposition, played a core role in protein body formation. ER swelled at the end to form many vesicles. ER was associated with the plasmodesmata, helped transporting nutrients at the development and differentiation stage.

内质网参与胚乳细胞构建中细胞壁物质的积累；内质网包裹基质形成吞噬体，为胚乳的发育提供营养；内质网槽库膨大，积累淀粉转变成淀粉质体；内质网参与蛋白质的合成与积累，在蛋白体的形成中处于核心地位；内质网末端节状膨胀，形成潴泡；灌浆高峰期内质网常与胞间连丝相连，有助于物质的运输。

Wilms" tumor is one of the most common solid tumors in children, and the genesis of Wilms" tumor is believed to be associated with delayed differentiation of metanephric blastema in fetus and retaining proliferation in postnatal period.

肾母细胞瘤（Wilms tumor， WT）是儿童最常见的实体瘤之一，其发病与后肾胚基细胞分化受阻并在出生后继续增殖有关。

The changes of oligosaccharides imply the glicoconjugates, including sialic acid, galactose and fucose may play important roles during implantation.

在着床期子宫内膜各种细胞的凝集素受体糖基呈现规律性变化，提示子宫内膜糖基的变化与胚泡着床密切相关。

Its histogenesis and pathogenesis are always arousing the enthusiasm of many researchers.

它由未分化的胚基、上皮和间质成分组成，其组织来源和发生学一直受到众多学者的关注。

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。

At the reproductive stage, RA68 was expressed in the inflorescence meristem, the tip of rachis branch, spikelet primordia, macrospore sac and pollen grains.

原位杂交分析结果表明：在幼苗期RA68主要在幼芽胚芽鞘的内外层细胞和幼叶原基的表层细胞中表达；转入生殖生长期后，在花序分生组织、枝梗原基顶端、花器官原基、大孢子囊和花粉粒中表达。

Bead by, nucellus radical ministry and the place with bead confluent handle are called close a point , it is the place that bead handle vascular bundle enters gastrula.

珠被。珠心基部与珠柄汇合的部位称为合点，是珠柄维管束进入胚囊的位置。

FOXC2 protein and mRNA were extensively expressed in pregnant 40 day embryonic somite and neural tube mesoderm which would form cardiovascular and axial skeleton primordia, especially strong expressed in the cells of mesenchyme surrounding notochord and dorsal aorta approaching the head.

这个基因广泛表达在孕40天胚胎体节和神经管周围未来分化为心血管和中轴骨骼始基的中胚层，靠近头部围绕脊索和背主动脉的间充质细胞核中表达强烈。

This result indicates that WT1 gene plays an important role in differentiation and development of fetal kidney and may be the factor that promotes metanephric blastemal cell to differentiate into epithelial cell.

结果显示小胎龄肾组织中WT1蛋白在胚基细胞和幼稚肾小球细胞核表达而大胎龄组肾组织中WT1在肾小管细胞胞浆表达，阳性率分别为57.1％(8/14)和46.2%(6/13)，提示WT1基因在胚胎肾分化发育的过程中起着重要作用，WT1蛋白可能是促进后肾胚基细胞向上皮细胞分化的调控因子，其表达在时间上和空间上都受到严格的调控，WT1的表达异常可能导致胚基细胞分化停滞。17例肾母细胞瘤WT1蛋白表达阳性率为41.2%(7/17)，阳性部位在胚基型和上皮型肿瘤细胞核，表达部位和阳性率与早期胚胎肾相似，其中间质型肾母细胞瘤均为阴性，胚基型和上皮型肾母细胞瘤阳性率70%(7/10)，两组间阳性率有显著差异。

AMELX, AMBN and ENAM are the major matrix proteins of enamel, and play different roles during different developing stages of tooth germs. AMELX may facilitate the growth of crystals in the early mineral stage, and act in the repairing of bone. AMBN may promote the mineralization of enamel matrix, and also keep the shape and size of crystals. ENAM may act in remineralization and promoting the growth of crystals.

AMELX、AMBN和ENAM为主要的釉质基质蛋白，在牙胚发育的不同阶段有不同的调节矿化的作用，AMELX在釉质矿化早期促进晶体生长，而其在骨中的表达则进一步表明其在骨修复中可能的作用；AMBN促进釉质基质矿化，并维持晶体形状、大小；ENAM促进和维持晶体生长，并与再矿化有关。
