Fig. 4From: Urinary nephrospheres indicate recovery from acute kidney injury in renal allograft recipients – a pilot studyDual color confocal microscopy of cytospin preparations of freshly isolated nephrospheres. Depicted are nephrospheres from a patient with the phenotype AQP1−/CASR+ (upper panel) and a patient with the phenotype AQP1+/CASR+ (lower panel). A mitotic structure is indicated by an arrow. AQP1 expression is indicated as green, CASR expression as red, DAPI is blueBack to article page
