1、中华保健医学杂志2010年10月第12卷第5期ChinJHealthCareMed,October2010,Vol12,No.5血管内皮祖细胞参与肺癌组织血管形成的实验研究谢晓,梅举,钟弘,丁芳宝,鲍春荣[摘要]目的利用血管内皮祖细胞(endothelialprogenitorcells,EPCs)在血管形成过程中的积极作用,研究其参与肺癌组织的血管形成的特点。方法采用外周血单个核细胞体外经定向分化、培养为EPCs,并用4,6一联脒一2一苯基吲哚(DAPI)荧光标记.将DAPI荧光标记的EPCs与人肺癌细
2、胞株SPC—A1同时给BALB/C裸鼠(B组)皮下注射,观测肿瘤生长情况,并与单纯接种SPC—At裸鼠(A组)比较。结果EPCs能从人外周血获得,可体外扩增约100倍。接种荷瘤后,A组裸鼠平均寿命为85+9d,B组为78+8d:A组肿瘤平均体积为1.44_+0.45cm,B组为1.83_+0.32cm。A组与B组相比,裸鼠平均寿命和肿瘤体积大小差异均有统计学意义(P<0.05,P<0.01)。结论EPCs能参与肺癌组织血管形成,促进肺癌生长,使裸鼠寿命缩短。[关键词]血管内皮祖细胞;肺肿瘤;血管新生;裸鼠
