| 1 | TGF-β 1对肺癌干细胞和非干细胞增殖的影响显示文摘目的:研究TGF-β1对肺癌干细胞和非干细胞增殖的影响,为深入研究肺癌干细胞增殖与分化的分子调控机制奠定基础。方法:利用无血清培养基从人大细胞肺癌组织中分离、培养肿瘤细胞,并建立大细胞肺癌细胞系。以流式细胞术分选表达CD44和(或)CD90的肺癌细胞亚群,通过细胞球形成实验及X射线敏感实验鉴定分选的肺癌干细胞。用流式细胞术及细胞增殖抑制实验检测TGF-β1对肺癌干细胞生长的影响。结果:成功地培养出高纯度的原代大细胞肺癌细胞,其传代次数可达30代以上。应用CD44和CD90共同标记,可将大细胞肺癌细胞分为4亚群,分别是CD44+CD90+、CD44+CD90-、CD44++CD90+和CD44++CD90-细胞,其中CD44++CD90+细胞比例为0.4%。相比于其他细胞亚群,有较多的CD44++CD90+细胞为间质细胞样形态,它们形成细胞球的能力最强,对X射线照射的抵抗力也最强。TGF-β1能抑制肺癌细胞的增殖,并促使它们向间质细胞样形态转化。TGF-β1可抑制各亚群肺癌细胞的增殖,但对CD44++CD90+细胞的抑制能力最弱,而对CD44+CD90-细胞的抑制能力最强;培养体系中加入TGF-β1后CD44++CD90+细胞的比例逐步升高,去除TGF-β1后CD44++CD90+细胞的比例又逐渐降低。结论:CD44++CD90+细胞可能是大细胞肺癌的干细胞,TGF-β1能显著抑制肺癌非干细胞的增殖,从而相应地富集了肺癌干细胞。 | 高全立 汪萍 Gunnar Kvalheim Gustav Gaudernack | 2010 | 中国肿瘤生物治疗杂志2010,17,4: | 5 |
| 2 | Electrochemical Behavior of Dissolved Fe_2O_3 in Molten CaCl_2-KF显示文摘The electrochemical behavior of dissolved Fe2O3 in 82.5CaCl2-17.5KF(mole percent,%)was studied using cyclic voltammetry,chronoamperometry,and galvanostatic electrolysis at 827 ℃,and the deposits were characterized by XRD and SEM.Pure iron was deposited on a rotating cylinder(210 r/min)with a cell voltage less than-1.0 V.Deposition rate was controlled by diffusion on a molybdenum electrode.The diffusion coefficient of iron species Fe(Ⅲ)in the melt at 827 ℃ was found to be 9.7×10-5 cm2/s. | WANG Shu-lan Geir Martin Haarberg Eirin Kvalheim | 2008 | Journal of Iron and Steel Research(International)2008,15,6: | 4 |
| 3 | 大细胞肺癌干细胞样细胞的分离及鉴定显示文摘目的:从大细胞肺癌组织中分离、鉴定肺癌干细胞样细胞,为进一步研究靶向肺癌干细胞的免疫治疗奠定基础。方法:利用无血清培养基从大细胞肺癌组织中分离、培养肿瘤细胞并建立大细胞肺癌细胞系。流式细胞仪分选表达CIM4和(或)CD90的不同肺癌细胞亚群,通过单细胞克隆形成实验、平板集落形成实验、细胞球形成实验及X射线敏感实验研究不同肺癌细胞亚群的生物学特性。结果:应用原代细胞培养技术成功地从大细胞肺癌组织中培养出高纯度的原代肿瘤细胞,命名为LC006细胞,其传代次数可达30代以上。流式细胞仪分析显示,LC006细胞中有1.0%的细胞CD44呈强阳性表达(CD44^++)。相比于主群的CD44弱阳性(CD44^+)细胞,CD44^++LC006细胞具有较强的平板集落形成能力,可形成holoelone克隆和细胞球;而CD44^+LC006细胞不能形成holoclone克隆和细胞球。应用CD44和CD90抗体可将LC006细胞分为4个亚群,分别是CD44^+CD90^+(12.8%)、CD44^+CD90^-(86.3%)、CD44^++CD90^+(0.4%)和CD44^++CD90^-(0.5%)细胞;相比于其他细胞亚群,CD44^++CD90^+LC006细胞形成细胞球的能力最强,对X射线的抵抗力也最强。结论:成功分离和鉴定的CD44^++CD90^+LC006细胞是大细胞肺癌的肿瘤干细胞样细胞。 | 高全立 汪萍 Gunnar Kvalheim Gustav Gaudernack | 2010 | 中国肿瘤生物治疗杂志2010,17,3: | 3 |
