摘 要:目的:探讨乙酰胆碱(Ach)对人表皮细胞冷存活力的影响。方法:应用人表皮细胞的分离、培养技术,并进行MTT检测、病理切片以及电镜检测等手段进行观察。结果:不同浓度的Ach对冷存的表皮细胞均有一定的保存活力作用,其中以10-8~10-10mol/L的浓度为最佳。结论:认为Ach对冷存中的人表皮细胞有一定的保护作用,它可提高表皮细胞的保存活力。

Abstract:Objective: To investigate the effect of acetylcholine (Ach) on the preservation of human keratinocytes. Method: Use tissue engineering technology to separate and culture human keratinocyte in vitro and observe them using MTT method and histological and electron microscopic methods. Result: Different concentration of Ach can preserve more viability of human keratinocytes. The best concentration is 10-8 to 10-10 mol/L. Conclusion: Ach can preserve more viability of human kerationcytes during preservation.
Keywords:Acetylcholine; Human keratinocyte; Cell preservation
