查询词典 extracellular

The essential events of the process are detachment, intravasation, circulation, arrest, extravasation, angiogenesis and proliferation, which come down to interactions of neoplastic cells with host cells and extracellular matrix -governed by adhesion, migration, invasion, proteaselysis, and the complicated signal transduction.

而所有步骤均可归结为癌细胞与宿主细胞及细胞外基质(Extracellular Matrix，ECM)之间的相互作用——粘附、浸润、移动、蛋白酶分泌以及复杂的信号转导过程，基于细胞信息传递和调控在细胞生命活动中处于主导地位，癌细胞信号转导系统的作用及相关机制对于揭示肿瘤转移的本质，探索新的抗肿瘤转移途径具有十分重要的作用。

Results:①In normal extracellular solution, the non-selective cholinergic agonist acetylcholine and the muscarinic agonist muscarine both caused the increace of [Ca2+]i in separately 21 out of 25 and 14 out of 18 VHCs I, while only 3 out of 20 and 2 out of 16 VHCs I had a weak increase of [Ca2+]i if investigated in calcium free extracellular solution; nicotine could increase the [Ca2+]i in 7 out of 32 VHCsⅠonly at enough high concentration(up to 10 mmol/L) in normal extracellular solution, this [Ca~(2+)]_i increase by nicotine at high concentration could not be investigated if at calcium free solution.

结果①非选择性胆碱能受体激动剂乙酰胆碱、M型胆碱能受体激动剂毒蕈碱在正常细胞外液中均可引起大部分(21/25， 14/18)单离VHCⅠ[Ca~(2+)]_i的升高，但无钙外液中ACh、muscarine仅使少部分(3/20，2/16)VHCⅠ[Ca~(2+)]_i升高且作用减弱；正常外液中，N型受体激动剂尼古丁仅在高浓度(≥10 mmol/L)时引起部分(7/32) VHCⅠ[Ca~(2+)]_i升高，在低浓度时对胞内钙离子浓度影响不明显，无钙外液中，10 mmol/L nicotine对胞内钙离子浓度影响不明显。

In the latter generations of rice suspension cell, the activity of extracellular POD and the cell suspensibility curve raises at first and then declines. The activities of extracellular POD induced by exogenous H_2O_2, CaCl_2 and VK3 are different and the same concentration of VK3, CaCl_2, H_2O_2 can all inhibit extracellular POD activities, especially to the callus tissue subculturing for six times.

外源H_2O_2，CaCl_2与VK3诱导悬浮细胞所产生的胞外POD活性并不相同，相同浓度的VK3、CaCl_2和H_2O_2都抑制胞外POD活性，对继代六次的愈伤组织的悬浮细胞胞外POD活性影响最大，H_2O_2对POD的抑制作用更为强烈。H_2O_2随浓度和处理时间的增加，使胞外POD的活性减弱；处理6h、12h，胞外POD活性随着VK3和CaCl_2浓度的增加而增强，但处理48h胞外POD活性随浓度的增加而减弱。

However, at the beginning of PVR process, stimulated and activated by the initiative factors, RPE begin to dislocate from Bruchs membrane , migrate, proliferate, dedifferentiate, transdifferentiate and secrete provisinal extracellular matrix proteins, followed by membrane formation and contraction on both surfaces of the neuroretina and in the vitreous body, resulted in tractional retinal detachment.

PVR发生后，RPE受到始动因素的刺激，开始活化，脱离原位，去分化，移行、增生、发生表型转化等，并分泌细胞外基质(extracellular matrix， ECM)，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

20 Centuries 60 time, american Gristina put forward, all biology material are embedded inside body hind, its surface all can form a kind of biomembrane, bacterial criterion is many in this kind of biomembrane progenitive, the many mucilage outside producing a cell is qualitative (Extracellular Slime Substance, ESS), it is the easy hair sex that causes false body infection and the main factor that study a gender hard.

概要： 20世纪60年代，美国Gristina等提出，所有的生物材料植入体内后，其表面均能形成一种生物膜，细菌则在这种生物膜中大量繁殖，并产生细胞外多粘质物质(Extracellular Slime Substance，ESS)，是导致假体感染的易发性和难治性的重要因素。

SPARC (secreted protein, acidic and rich in cysteine) is a multifunctional glycoprotein, which influences many important physiological and pathological processes, such as modulating cellular interaction with the extracellular matrix, abrogating cell focal adhesions, inhibiting cellular proli-feration, and regulating the activity of growth factors.

SPARC (secreted protein， acidic and rich in cysteine)即富含半胱氨酸的酸性蛋白，为一种多功能糖蛋白，在各种生理与病理过程中发挥作用，如调节细胞与细胞外基质(extracellular matrix， ECM)相互作用、溶解黏着斑完成抗黏附反应；抑制细胞增殖及调节生长因子活性等。

In the precessing of tumor invasion and metastasis, extracellular matrix and basement membrane are playing an important role of barrier.

在肿瘤的侵袭和转移过程中，细胞外基质(extracellular matrix，ECM)和基底膜(basement membrane，BM)起着重要的屏障作用。

Fibronectin is a very important biological molecule in collagen glucoprotein that plays a number of important roles in the extracellular matrix. It has roles in structural support and signaling cues for cell survival, migration, differentiation, gene expression, growth factor signaling, cell contractility, epithelial tissue repair, alignment regularization and organism immunoregulation.
