摘要:

背景:脐带间充质干细胞的临床应用面临移植前保存的问题,而临床保存介质对移植前细胞活性的影响直接关乎移植后疗效,目前却缺乏对临床介质保存效果的系统性研究。
目的:评价临床常用保存介质对脐带间充质干细胞活性的影响。
方法:在4 ℃与室温(25 ℃)条件下,将脐带间充质干细胞在临床常用保存液(0.9%氯化钠注射液,5%葡萄糖注射液和1%人血白蛋白溶液)中保存2,4,6 h,观察上述保存介质对脐带间充质干细胞活性、凋亡/死亡率、多向分化能力及DNA损伤的影响。
结果与结论:无论在4 ℃还是室温条件下,细胞在临床常用保存介质中的活性均在短期内呈时间依赖性下降。此外,不同保存介质引起细胞死亡而非凋亡,且死亡率呈时间依赖性增加;经不同介质保存后,细胞出现DNA损伤,但其增殖与多向分化能力未受明显影响,提示细胞核DNA损伤为细胞活性下降的关键因素。

Abstract:

BACKGROUND: Umbilical cord-mesenchymal stem cells (UC-MSCs) have been widely studied in clinics. Notably, UC-MSCs have to be properly preserved before clinical use and the effects of storage solution on viability of cells play critical roles in the effectiveness of cell-transplantation. However, there are few studies concerning this phenomenon.
OBJECTIVE: To evaluate the effects of various clinical common solutions on the activity of UC-MSCs.
METHODS: UC-MSCs were stored at 0.9% sodium chloride injection, 5% glucose injection and 1% human serum albumin respectively at 4 ℃ and room temperature (25 ℃) for 2, 4 or 6 hours. Viabilities, apoptosis/necrosis rate, multi-differentiation ability of preserved UC-MSCs and DNA damage were examined.
RESULTS AND CONCLUSION: The viabilities of UC-MSCs were rapidly decreased time-dependently in all of the storage solutions both at 4 ℃ and room temperature. Besides, the storage solutions resulted in cellular necrosis rather than apoptosis and the necrosis rate was greatly increased time-dependently. DNA damage was observed in cells after preserved in various storage solutions, but cell proliferation and differentiation were not affected, which demonstrated that DNA damage may be a key factor for the reduction of cell viabilities.
