Then, under the control of systemic factors, mesenchymal cells aggregate and differentiate to form catilage blastemal elements that prefigure skeletal limb components.

脊椎动物胚胎期骨与关节系统的发生是一种复杂生命现象，起始于中胚层间充质细胞的定向聚集，形成肢芽，然后在一系列作用因子的调控下，肢芽内细胞进一步分化，形成具有骨骼雏形的软骨原基，后者经软骨内骨化发育成骨。

It was found that the extract of Ficus carica leaves showed remarkable inhibitory and killing effects on the Newcastle disease virus.

采用组织细胞培养技术，充分利用无花果叶提取物中的有效成分，在人上皮样癌（Hep-2）细胞株、地鼠肾（BHK21）细胞株和鸡胚成纤维细胞上研究其抗新城疫病毒的作用。

OBJECTIVE: To observe the inhibitory effects of hAS/293 and hES/293 cells on angiogenesis in chick chorioallantoic membrane.

目的：观察以基因工程技术构建的人血管抑素/293细胞和人内皮抑素/293细胞对鸡胚尿囊膜血管新生的抑制效应。

The terpenoid and its crude extracts were used to treat on blood vessel of chick chorioallantoic membrane, as well as human umbilical vein endothelial cell.

通过鸡胚绒毛囊膜和人脐静脉内皮细胞研究了白芨中萜类化合物及其粗提物对血管及血管内皮细胞的抑制作用。

We derived cell populations with properties of ectodermal and mesenchymal cells in 2D culture and incorporated these divergent cell populations into 3D epithelial tissues.

我们利用二维培养将胚胎干细胞分化为具有外胚和间充质特性的细胞，再将这些细胞复合入三维上皮组织。

These cells are known as endodermal cells.

这些细胞称为内胚层细胞。

At the fifth passage, two cell strains were made into cell suspension at l×10^9L^(-1). 0.5 mL was subcutaneously incubated at the inguina of each rat for 8 weeks. Amplified cells were cultured in PGC culture medium and non-adherence culture flask till idiosome formed, adhered and differeotiated.

体内实验取连续传5代的2个细胞株，分别制备浓度为l×10^9L^(-1)的细胞悬液，于每只小鼠两侧腹股沟处皮下各接种0.5 mL，培养8周体外分化采用无私附特性的培养瓶和除去白血病抑制因子的原始生殖细胞培养液，以脱饲养层法悬浮培养扩增的细胞，直到拟胚体形成及贴壁分化。

Lots of starch grains in nucellar cells and integumentary cells surrounding endosperm haustoria decreased and disappeared with the development of endosperm haustoria.

随着胚乳吸器的发育，吸器附近的珠心细胞和珠被细胞中贮存的大量淀粉粒逐渐减少和消失。

Renal-cell carcinoma, clear-cell sarcoma, mesoblastic nephroma, rhabdoid tumour, and renal medullary carcinoma form a heterogeneous group of childhood renal malignancies known as non-Wilms' tumours.

肾细胞癌、透明细胞肉瘤、先天性中胚叶肾瘤、横纹肌样瘤以及肾髓质癌均为来自于名为非 Wilm 肿瘤的一种儿童肾脏恶性肿瘤。

We show that these pATSCs can differentiate into several mesodermal lineages, as well as neural lineage cells.

我们发现这些基质细胞不但能向多个胚层分化而且还能分化为神经系细胞。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
