Research Abstract

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.
