Aims: To investigate whether bone marrow derived mesenchymal stromal cells (BMSC) have ameliorated ischemia/reperfusion injury-induced acute kidney injury (IRI-AKI) via tumor necrosis factor-inducible gene 6 protein (TSG-6) and how TSG-6 exerted this effect.
Methods: We used lentiviral vectors of short hairpin RNA (shRNA) targeting TSG-6 gene to silence TSG-6 in BMSC. And TSG-6-silenced BMSC were administrated into IRI-AKI rats. Then we analyzed serum creatinine (Scr) and renal histology of IRI-AKI rats treated with BMSC after different pretreatments. Furthermore, we explored the effect of TSG-6 on renal tubular epithelial cells proliferation and assays.
Results: The Scr levels of IRI-AKI rats treated with BMSC (73.5±7.8 mol/L) significantly decreased compared to those of IRI-AKI rats treated without BMSC (392.5±24.8 mol/L, P<0.05) or with DMEM (314.0±19.8 mol/L, P<0.05). Meanwhile, the renal tissue injury in IRI-AKI rats treated with BMSC improved markedly. However, the Scr levels of IRI-AKI rats treated with TSG-6-silenced BMSC (265.1±21.2 mol/L) significantly increased compared to those with BMSC (74.0±8.5 mol/L, P<0.05). The proportion of Ki67-positive cells was reduced in IRI-AKI rats treated with TSG-6-silenced BMSC compared to that in IRI-AKI rats treated with BMSC (29.7±0.8% versus 43.4±3.0%, P<0.05). , the cell proliferation rate of TSG-6-stimulated NRK-52E cells under hypoxia (89.2±3.9%) increased significantly compared to that of NRK-52E cells alone under hypoxia (82.4±0.8%, P<0.05). Similarly, the proportion of Ki67-positive cells was significantly elevated in TSG-6-stimulated NRK-52E cells under hypoxia. Furthermore, TSG-6 could inhibit infiltration of neutrophils in kidney tissue of IRI-AKI.
Conclusions: TSG-6 plays a key role in the treatment of IRI-AKI with BMSC, which may be due to its effect on promoting renal tubular epithelial cells proliferation by modulating inflammation.
