From: Bone Morphogenetic Protein (BMP)-7 expression is decreased in human hypertensive nephrosclerosis
Immunofluorescence of BMP-7 and Aquaporin 1 and Aquaporin 2 in nephrosclerotic kidneys showing decreased expression of BMP-7. Double immunofluorescence of BMP-7 with aquaporin-1 (AQ-1) and aquaporin-2 (AQ-2): BMP-7 staining is red (rhodamine red, A, B), double-labeling of BMP-7 and AQ-1 (C) or AQ-2 (D) is stained organge. Expression of BMP-7 was lower than in the control kidneys demonstrated by the lower staining intensity of BMP-7 despite a longer exposure time and therewith a stronger intensity of AQ-1 and AQ-2.
