renal papilla

Strong evidence suggests that renal stem cells are located in the renal papilla.

Adhering to cells on the surface of a renal papilla, a seed crystal can grow and aggregate into an organized mass.

Each renal papilla is surrounded by a branch of the renal pelvis called a calyx.

The renal papilla is the location where the medullary pyramids empty urine into the minor calyx in the kidney.

The terminal portions of the medullary collecting ducts are the "papillary ducts", which end at the renal papilla and empty into a minor calyx.

Medullipin is a hormone created by the interstitial cells of renal papilla, which is converted to medullipin II in the liver.

Renal papillary necrosis is a form of nephropathy involving the necrosis of the renal papilla, which is supplied by the vasa recta.

The pathogenesis of papillary necrosis has been investigated in mice, and mononuclear inflammatory infiltration in the renal papilla resulting from ketamine dependence has been sugested as a possible mechanism.

Urine formed in the kidney passes through a renal papilla at the apex into a minor calyx then into a major calyx before passing through the renal pelvis into the ureter.
