Aim To study the injury effect of lipoprotein (a) [Lp(a)] on biological function of mouse bone marrow-derived endothelial progenitor cells (EPC). Methods EPC were divided into control groups ａnd five treatment groups with different concentrations (1, 10, 100, 300 ａnd 600 mg/L) of Lp(a). EPC were isolated by adherence culture ａnd identified by binding of UEA-1, ａnd uptake of acetylated low density lipoprotein (ac-LDL). The abilities of survival, migration ａnd adherence were detected by the MTT, Transwell ａnd gelatin adherence assays respectively. The total length of the tube structures in each photograph was measured using Adobe Photoshop software 7.0. Results Lp(a) dose-dependently decreased the surival rate of EPC, 100 mg/L Lp(a) reduced it significantly ａnd the maximum injury concentration was 300 mg/L. A significantly reduced migratory rate of EPC could be seen after treatment with 1 mg/L Lp(a), the ｃount of the migratory cells was less than 1/6 of the control, so 1/9 for 10 mg/L Lp(a) ａnd 1/14 for 300 mg/L Lp(a). EPC treated with Lp(a) showed a dose-dependent decrease of adhesion to gelatin. 1 mg/L Lp(a) markedly decreased the number of adhesive cells (145.2±8.4/every field vs 115.2±12.6/ every field, P<0.05, n5). When EPC were exposed to 10 or 100 mg/L Lp(a), the capability of adhesion had further descended. When at 300 mg/L, it was remarkably descent to 1/16 of control. Treatment with 10 mg/L Lp(a) impaired the ability of EPC to form tube structures. EPC cultivanted with 100 mg/L had presented decreased tube formation ａnd was less than 1/4 of control (36.34±1.54 mm/field vs 8.76±0.62 mm/field, P<0.001, n5), ａnd when incubated at 300 mg/L of Lp(a), the integrity tube structure was severely disrupted.
样品的处理及保存方法
人血管内皮细胞生长因子抗体（VEGFAb）elisa试剂盒
1、 血清－－－－-操作过程中避免任何细胞刺激。使用不含热原和内毒素的试管。收集血液后，1000×g离心10分钟将血清和红细胞迅速小心地分离。
2、 血浆－－－－-EDTA、柠檬酸盐、肝素血浆可用于检测。1000×g离心30分钟去除颗粒。
3、 细胞上清液－－-1000×g离心10分钟除颗粒和聚合物。
4、 组织匀浆－－－－-将组织加入适量生理盐水捣碎。1000×g离心10分钟，取上清液
5、 保存－－－－－－如果样品不立即使用，应将其分成小部分-70 ℃保存，避免反复冷冻。尽可能的不要使用溶血或高血脂血。如果血清中大量颗粒，检测先离心或过滤。不要在37℃或更高的温度加热解冻。应在室温下解冻并确保样品均匀地充分解冻。
