Inhibition of angiogenin by ribonuclease/angiogenin inhibitor 1 (RNH1) results in a reduction in the ability of SDF-1mig cell-conditioned medium to stimulate the formation of stress granules. Images show the eIF3 granules in cardiomyocytes exposed to the SDF-1mig BM-MNC-conditioned medium in the absence (i) or presence (ii) of RNH1 (OriGene TP308360). Myocyte cytoplasm was labeled with alpha sarcomeric actinin (iii). DAPI stained the nuclei. Figure cited from Stem Cell Res Ther, PMID: 25889213
