DROSHA and acute kidney injury: Evaluation of whether miRNAs deregulation constrains the regenerative competencies of MSCs- exosomes in a model of glycerol-induced acute kidney injury (AKI) in severe combined immunodeficient mice showed that kidney genes deregulated following damage were alleviated via MSCs- exosomes treatment but not via Drosha-knockdown vesicles, thus signifying a crucial role of miRNAs in recovery after AKI [104].
