Localization of juxtacrine factor ephrin-B2 in pituitary stem/progenitor cell niches throughout life.

abstract：:The juxtaglomerular apparatus (JGA) in the rabbit kidney was examined by transmission electron microscopy and by freeze fracturing. It was found, that the Goormaghtigh cells of the JGA are extensively coupled with the mesangial cells within the glomerular tuft by gap junctions. A broad band of gap junctions starting w...
