extraglomerular mesangial cell

It contains three components: the macula densa, juxtaglomerular cells, and extraglomerular mesangial cells.

Adenosine may then bind to adenosine A receptors on extraglomerular mesangial cells, triggering a rise in intracellular calcium levels.

Extraglomerular mesangial cells (also known as Lacis cells, Goormaghtigh cells, or Polkissen cells) are light-staining cells in the kidney found outside the glomerulus, near the vascular pole and macula densa.
