上腺素 (AM) 与骨髓单核细胞 (MNC) 结合,显著改善了后肢缺血的血液流动. 这种组合疗法比单独的MNC更有效地增强血管生成和细胞存活.

科学领域:

  • 心血管研究研究心血管研究
  • 再生医学是一种再生医学.
  • 血管生物学 血管生物学

背景情况:

  • 众所周知,阿德里诺美杜林 (AM) 抑制内皮细胞的亡并促进血管生成.
  • 需要进一步研究AM增强由骨髓细胞诱导的血管生成的潜力.

研究的目的:

  • 在后肢缺血的老鼠模型中,研究上腺素 (AM) 是否增强由骨髓衍生单核细胞 (MNC) 诱导的血管生成.

主要方法:

  • 后肢缺血的老鼠接受了AM输液加MNC移植,单独AM输液,单独MNC移植或车辆控制.
  • 使用激光多普勒对血液输液进行了评估.
  • 毛细血管密度和体外/体内对多国企业的影响被评估.

主要成果:

  • 与对照组相比,AM和MNC组显示血液 perfusion 显著改善.
  • AM和MNC的组合 (AM+MNC组) 导致血液 perfusion 和最大的毛细血管密度的最显著改善.
  • 实验室研究表明,AM抑制了MNC细胞亡,并促进了粘附和分化到内皮原生细胞中.

结论:

  • 与单独的MNC移植相比,将AM输液与MNC移植相结合显著改善了后肢缺血的结果.
