Localization of Connexin (Cx)45 transcription in Cx45+/− mouse kidney sections by X-Gal staining. A: β-gal was detected in the renal cortex, predominantly in vasculature (arrow) and glomeruli (arrowhead). B and C: within the juxtaglomerular apparatus (JGA), β-gal staining was observed in the afferent (AA) and efferent arterioles (EA), as well as the extra- and intraglomerular mesangial cells (arrows). D: no β-gal staining was detected in sections from Cx45+/+ mouse kidneys; G, glomerulus. Bar = 50 μm.
