Fig. 5From: Ultrasound enhances the therapeutic potential of mesenchymal stem cells wrapped in greater omentum for aristolochic acid nephropathyThe distributions of RFP-MSCs in left kidney tissues of AAN + saline and AAN + MSC mice. MSCs did not enter the renal parenchyma, as observed using two-photon fluorescence imaging (60× oil lens; scale bar = 25 μm). The autofluorescence (green) of the kidney was used as the background referenceBack to article page
