Expression of Angiotensin II Receptor-1 in Human Articular Chondrocytes
AT1R protein expression in chondrocytes. (a) Western Blotting. Chondrocytes with or without IL-1 stimulation were analyzed: AT1R: approximately 60 kD (see text), GAPDH: 36 kD. (b) Flow Cytometry. A representative result is shown, shaded area: control staining, solid line: nonstimulated chondrocytes, dotted line: IL-1-stimulated chondrocytes. Representative results of 2 OA samples are shown.
