Figure 1
Photomicrograph of the biosensor technique for assessing PGE2 release at the basolateral membrane of MD cells. The glomerulus (G) has been dissected away from the MD plaque. A single HEK/EP1 cell is loaded with fura-2 and held with a pipette (arrowhead) positioned at the MD basolateral membrane surface while perfusing the intact cTAL.
