Ischemia-reperfusion injury is an important contributor to acute kidney injury and a major factor affecting early functional recovery after kidney transplantation. We conducted this experiment to investigate the protective effect of induced multipotent stem cell transplantation on renal ischemia-reperfusion injury. Forty rabbits were divided into four groups of 10 rabbits each. Thirty rabbits were used to establish the renal ischemia-reperfusion injury model, and ten rabbits served as the model group and were not treated. Among the 30 rabbits with renal ischemia-reperfusion injury, 10 rabbits were treated with induced peripheral blood mononuclear cells (PBMCs), and 10 other rabbits were treated with noninduced PBMCs. After three weekly treatments, the serum creatinine levels, urea nitrogen levels and urine protein concentrations were quantified. The kidneys were stained with hematoxylin-eosin (HE), periodic acid-Schiff (PAS) and Masson's trichrome and then sent for commercial metabolomic testing. The kidneys of the rabbits in the model group showed different degrees of pathological changes, and the recovery of renal function was observed in the group treated with induced cells. The results indicate that PBMCs differentiate into multipotent stem cells after induction and exert a therapeutic effect on renal ischemia-reperfusion injury.
缺血再灌注损伤是急性肾损伤的重要原因,也是影响肾移植后早期功能恢复的主要因素。我们进行这项实验旨在研究诱导多能干细胞移植对肾缺血再灌注损伤的保护作用。将 40 只兔子分为 4 组,每组 10 只。其中 30 只用于建立肾缺血再灌注损伤模型,10 只作为模型组,不进行治疗。在 30 只肾缺血再灌注损伤的兔子中,10 只接受诱导外周血单个核细胞(PBMCs)治疗,另外 10 只接受非诱导 PBMCs 治疗。经过 3 次每周的治疗后,定量检测血清肌酐水平、尿素氮水平和尿蛋白浓度。用苏木精-伊红(HE)、过碘酸-Schiff(PAS)和 Masson 三色染色,然后进行商业代谢组学检测。模型组兔子的肾脏出现不同程度的病理变化,而接受诱导细胞治疗的组兔子肾功能得到恢复。结果表明,PBMCs 在诱导后分化为多能干细胞,并对肾缺血再灌注损伤发挥治疗作用。
