Figure 2From: Mesenchymal stem cells ameliorate rhabdomyolysis-induced acute kidney injury via the activation of M2 macrophagesInfused MSCs persist in the lung and muscle and suppress tissue damage. (a) MSCs persisted in the lung and injured muscle 24 hours after rhabdomyolysis. RFP-labelled MSCs (red) were detected in vivo using two-photon fluorescence confocal microscopy. Nuclei were stained with DAPI (blue). Original magnification, ×600, n = 3. (b) Representative H & E-stained paraffin-embedded sections of kidney, gastrocnemius muscle and lung with or without administration of MSCs (n = 10). Mice were sacrificed 24 hours after rhabdomyolysis. (c) ELISA showed that MSC treatment significantly decreased the levels of both of the pro-inflammatory cytokines TNF-α and IL-6 and increased the anti-inflammatory cytokine IL-10. *P <0.05 versus RM + NS, n = 5. DAPI, 4,6-diamidino-2-phenylindole; MSCs, mesenchymal stem cells; NS, normal saline; RM, rhabdomyolysis.Back to article page
