内皮细胞层

Q3 : The endodermis is a layer of cells that performs an important physiological role.

内皮是一层具有重要生理角色的细胞。

We hypothesized that Notch signaling might play an important role in specifying endothelial progenitors from the mesoderm, given that this pathway acts as a bipotential cell-fate switch on equipotent progenitor populations in other settings.

由于在其他系统中的研究表明，Notch信号通路在同一潜能的前体细胞走向两种不同命运的过程中发挥着关键的转换作用，我们假定该通路在中胚层特化为内皮前体细胞的过程中也发挥重要功能。

Results The expression level of ERβ was moderate or highter in stroma cell, anterior pigment epithelium as well as pasterior pigment epithelium of the iris, unpigmented epithelium, pigmented ciliary epithelium and vascular endocemet of the choroid layers.

结果 ERβ在虹膜基质细胞、虹膜前后两层色素上皮细胞、睫状体非色素上皮和色素上皮、脉络膜各层血管内皮的表达水平主要呈中表达或高表达；ERα则表达不明显。

The pleural superficial blood vessels were smooth, while the constrictions of smooth muscle cells and round imprints of endothelial nuclei occurred on the surface of the subpleural and parenchymal arteriole and venule.

肺胸膜面浅层微血管的铸型表面光滑，胸膜下和肺实质内微动脉和微静脉的铸型表面可见平滑肌细胞形成的缩窄，以及圆形内皮细胞核的压痕。

The pleural superficial blood vessels were smooth, while the circular and oblique constrictions of smooth muscle cells occurred on the surface of the subpleural arteriole, venule and parenchymal venule. The round imprints of endothelial nuclei were found on the cast surface of the arteriole and venule.

胸膜面浅层的微血管铸型表面光滑，胸膜下微动脉或微静脉以及肺实质内微静脉的表面可以见到呈环形或斜形的平滑肌细胞的压迹，微动脉和微静脉的表面可见圆形内皮细胞核的压痕。

In resent year, several in vitro models for committed differentiation of ES cells have been described which give rise to a variety of cell types, including hematopoietic, neuronal, chondroitic, osteocytic, endothelial, myogenic, cardiac and smoothes muscle cells, but the committed differentiation into epidermal stem cells have not been reported.

ES细胞为研究基因功能、胚胎发生和个体发育，及组织细胞分化机理提供了理想的模型。近年来的研究表明，适当条件下，ES细胞可定向分化为三个胚层的各种类型的细胞，其中包括向神经元、造血细胞、成骨细胞、心肌细胞、血管内皮、软骨细胞、平滑肌特方向的定向分化。

There was mild cytologic atypia in one of the cases but no multilayering of endothelial cells in any case.

有1例的瘤细胞轻度异性，这6例均无多层内皮。

Results There were significant overexpressions of Bc-X in all layers of epidermis, inflammatory cells and vascular endothelia in dermis; there were mild up-regulations of Bax expression in stratum granulosum and stratum spinosum in the lesional skin.

结果 银屑病皮损中，Bcl-X在表皮各层、真皮炎症细胞及血管内皮的表达均较正常明显增高；Bax在颗粒层与棘层的表达轻度增高。

Results①The tunica intima and tunica media of the BVs were thin, the tunica adventitia was thick. No complete layer of smooth muscle was found in the tunica intima, the SMC with single elliptical or rod-shape nuclear, fusiform in shape and different in length, ran longitudinally and distributed unequally in the wall of BVs, intercrossed with each other, endothenial cell wasn't covered fully sometimes.

中膜未见完整平滑肌层，SMC呈梭形，大多呈纵切面，有的呈斜切面，不均匀地分布于管壁中；平滑肌纤维长短不一，相互交错排列，有时并不完全覆盖内皮细胞，细胞核单个，椭圆形或长杆状。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
