Spatial separation of muscarinic and purinergic signalling in arterial  endothelium.

 

The video shows a field of native endothelial cells (mesenteric artery) loaded with a fluorescence calcium indicator. In separate imaging sessions, endothelial calcium activity was stimulated by acetylcholine (ACh) or adenosine triphosphate (ATP). The calcium response to each is highlighted in colour (green for ACh, red for ATP).
