Angiostatin抑制轉(zhuǎn)移性腫瘤血管生成的數(shù)值模擬
摘要:針對(duì)某些原發(fā)性腫瘤能夠抑制遠(yuǎn)處轉(zhuǎn)移性腫瘤快速生長(zhǎng)的特性,建立轉(zhuǎn)移性腫瘤附近血管內(nèi)皮細(xì)胞遷移運(yùn)動(dòng)的二維、三維離散數(shù)學(xué)模型,對(duì)原發(fā)性腫瘤分泌的Angiostatin、轉(zhuǎn)移性腫瘤分泌的促血管生成因子(TAF)共同作用下轉(zhuǎn)移性腫瘤內(nèi)外微血管網(wǎng)的生成過(guò)程進(jìn)行數(shù)值模擬.結(jié)果表明,原發(fā)性腫瘤分泌的血管抑素對(duì)轉(zhuǎn)移性腫瘤內(nèi)外微血管網(wǎng)的生成速度、成熟度及血管分支數(shù)量均有明顯的抑制作用;可以降低轉(zhuǎn)移性腫瘤的血管化程度,有效抑制轉(zhuǎn)移性腫瘤的快速生長(zhǎng),達(dá)到治療腫瘤的目的;為腫瘤抗血管生成治療提供有益信息.Abstract:We present 2D and 3D discrete mathematical models for migratory response of endothelial cells inside and outside a metastasic tumor based on a physiological fact that some primary tumor can inhibit metastasic tumor growth quickly. In models we consider inhibitory effects of angiostatin excreted by primary tumor, chemotactic effects of TAF due to metastasic tumor and random movement of endothelial cells and simulate spatiotemporal evolution of microvascular network inside and outside the metastasic tumor. It shows that the angiostatin excreted by primary tumor has obviously inhibitory effects on vascular growth rates, bifurcation amount and development of microvascular network inside and outside the metastasic tumor. Inhibitory effects of angiostatin decrease revascularization of a metastasic tumor and suppress growth of the metastasic tumor in tumor therapy. It provides theoretical references for experimental research on clinical anti-angiogenesis. 作者: 趙改平[1] 陳二云[2] 沈力行[1] 吳潔[3] 許世雄[3] Author: ZHAO Gaiping[1] CHEN Eryun[2] SHEN Lixing[1] WU Jie[3] XU Shixiong[3] 作者單位: 上海理工大學(xué)醫(yī)療器械與食品學(xué)院,上海,200093上海理工大學(xué)能源與動(dòng)力工程學(xué)院,上海,200093復(fù)旦大學(xué)力學(xué)與工程科學(xué)系,上海,200433 期 刊: 計(jì)算物理 ISTICEIPKU Journal: CHINESE JOURNAL OF COMPUTATIONAL PHYSICS 年,卷(期): 2010, 27(2) 分類號(hào): H318.01 TB115 關(guān)鍵詞: 轉(zhuǎn)移性腫瘤 血管生成 Angiostatin 抑制效應(yīng) 數(shù)學(xué)模型 Keywords: metastasic tumor angiogenesis angiostatin inhibitory effects mathematical model 機(jī)標(biāo)分類號(hào): R73 R61 機(jī)標(biāo)關(guān)鍵詞: Angiostatin 抑制作用 轉(zhuǎn)移性腫瘤 腫瘤血管生成 數(shù)值模擬 Tumor Angiogenesis inhibitory effects endothelial cells 原發(fā)性腫瘤 experimental research mathematical models 快速生長(zhǎng) 抗血管生成治療 促血管生成因子 network 血管網(wǎng) 血管內(nèi)皮細(xì)胞 離散數(shù)學(xué)模型 分泌 tumor growth 基金項(xiàng)目: 國(guó)家自然科學(xué)基金,上海高校選拔培養(yǎng)優(yōu)秀青年教師科研專項(xiàng)基金,博士科研啟動(dòng)費(fèi)基金 Angiostatin抑制轉(zhuǎn)移性腫瘤血管生成的'數(shù)值模擬[期刊論文] 計(jì)算物理 --2010, 27(2)趙改平 陳二云 沈力行 吳潔 許世雄針對(duì)某些原發(fā)性腫瘤能夠抑制遠(yuǎn)處轉(zhuǎn)移性腫瘤快速生長(zhǎng)的特性,建立轉(zhuǎn)移性腫瘤附近血管內(nèi)皮細(xì)胞遷移運(yùn)動(dòng)的二維、三維離散數(shù)學(xué)模型,對(duì)原發(fā)性腫瘤分泌的Angiostatin、轉(zhuǎn)移性腫瘤分泌的促血管生成因子(TAF)共同作用下轉(zhuǎn)移性腫瘤...【Angiostatin抑制轉(zhuǎn)移性腫瘤血管生成的數(shù)值模擬】相關(guān)文章:
