Mesenchymal stem cell(MSC) is an attractive therapeutic cell source for treating renal diseases. MSC administration has been shown to improve renal function, although underlying mechanisms are incompletely understood. We recently showed that allogenic fetal membrane-derived MSC(FM-MSC), which is available non-invasively in large amounts, had renoprotective effect in an experimental glomerulonephritis model. Here, we investigated whether allogenic FM-MSC administration could protect kidneys from anti-Thy-1 glomerulonephritis or ischemia/ reperfusion(I/ R) injury. Histological examination revealed that FM-MSC administration significantly suppressed glomerular injury or I/ R injury. Administered FM-MSC were rarely observed in kidneys, but administration of FM-MSC increased serum IL-10 levels. In addition, renoprotective effects of FM-MSC were abolished by using anti-IL-10 neutralization antibody, suggesting that IL-10 would be one of the candidate factors to protect rat kidney from kidney injury. We concluded that allogenic FM-MSC transplantation is a potent therapeutic strategy for the treatment of kidney diseases.

间充质干细胞（MSC）是治疗肾脏疾病的有吸引力的治疗细胞来源。 MSC给药已被证明可以改善肾功能，尽管基本机制尚未完全理解。我们最近表明，在实验性肾小球肾炎模型中具有重大保护作用，可在无创量中获得同种异性胎儿衍生的MSC（FM-MSC）。在这里，我们研究了同种异体FM-MSC给药是否可以保护肾脏免受抗THY-1肾小球肾炎或缺血/再灌注（I/ R）损伤。组织学检查表明，FM-MSC给药可显着抑制肾小球损伤或I/ R损伤。在肾脏中很少观察到施用的FM-MSC，但是FM-MSC的给药增加了血清IL-10水平。此外，使用抗IL-10中和抗体消除了FM-MSC的肾脏保护作用，这表明IL-10将是保护大鼠肾脏免受肾脏损伤的候选因素之一。我们得出的结论是，同种异体FM-MSC移植是治疗肾脏疾病的有效治疗策略。
