上皮细胞

Objective Whether amniotic epithelial cells could promote the survival and differentiation of neural stem cells was explored in vitro.

目的：探讨羊膜上皮细胞是否能在体外促进胚胎脑神经干细胞的存活及分化。

Sham group was subjected with only anesthetization and laparotomy but not ischemia.

结果： 1。组织病理学观察：肾缺血再灌注损伤后肾小管上皮细胞形态和肾小管结构发生明显的病理改变。

We also observed an anteroposterior migration of medial edge epithelial cells, which may play an important role in posterior palate fusion.

作者还观察到中脊上皮细胞前后向的迁移，这种机制可能在后部腭板的融合中起到重要作用。

The score of renal calcium oxalate crystallization of 12%,25% medlar soak and apozem was reduced 38.7%, 54.8% and 48.4%, 58.1%(P.01) compared with the ethylene glycol drinking group. Conclusions: LBP can reduce the formation of renal calcium oxalate crystallization. The mechanism is to protect from damage by free radical and reduce the apoptosis of renal tubular epithelial cell by hyperoxaluria.

适量的枸杞多糖可减少饮用诱石剂大鼠的肾草酸钙结石形成，其作用机制是通过抗氧化反应，减少自由基对肾组织的损伤，从而减少高草酸尿对肾小管上皮细胞的凋亡。

AIM: To investigate the effects of Aspergillus fumigatus extract on the expressions of Muc5ac in human bronchial epithelial cells and its possible mechanism.

目的：探讨烟曲霉菌对呼吸道上皮细胞的黏液蛋白Muc5ac表达的影响及其可能机制。

Of the four Shigella, S. flexneri is mainly responsible for the endemic form of bacillary dysentery in our country.

福氏志贺氏菌是一种兼性胞内细菌病原体，通过一种称为病原体诱导的胞饮过程侵袭人结肠上皮细胞。

Transmission electron microscopy examination: epithelium cells degeneration, chromatin margination and collagen arrangement disorder could be observed at early stage after bothsided LASIK.

透射电镜下：BSL术后早期上皮细胞轻微变性，少量纤维细胞核染色质边集，角膜瓣边缘局部胶原排列稍紊乱。1mo时基质胶原纤维排列整齐，直径大小一致。

These findings indicate variable patterns of bronchiolar epithelial cytokine expression depending on the duration of CS exposure, and that complex mechanisms govern bronchiolar molecular dynamics in vivo.

此研究表明CS不同暴露时间导致细支气管上皮细胞因子表达的差异。这种复杂的机制支配着体内细支气管分子动力学。

Meanwhile we describe a simple and efficient method for culturing bronchiolar epithelial ant tumor tissue with MCDB151 serum-free medium, supplemented with hormones and growth factors.

我们的研究结果表明：Fez1在正常肺组织和癌旁支气管上皮细胞中正常表达，在肺癌中57.37％表达下调或不表达。

At 4th week, the percentages of Clara cells over bronchiolar epithelial cells were similar between groups. At 24th week, the percentages of Clara cells were reduced in mice exposed to TCDD, NNK, CSC, or TCDD+CSC exposure, but not in mice exposed to TCDD+1 mg NNK. Thus, these findings suggested that TCDD, NNK, CSC, or TCDD+CSC exposure injuried Clara cells to lose CCSP protein in mice lung.

在A/J mice 4周实验组中，TCDD或NNK各实验组Clara cell的数目(26.6%-34.3%)与控制组(34.2%)比较，并没有明显的差异；反观A/J mice 24周实验组中，除了TCDD+NNK (1 mg)实验组外，其他各实验组Clara cell的数目与控制组(55.9%)比较明显下降11.7%-41.4%，显示暴露NNK、TCDD、CSC或TCDD+CSC皆会伤害Clara cell，暗示Clara cell对这些环境毒物比其他呼吸道上皮细胞敏感。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
