Figure 2
Schematic showing the structural and functional relationships within the JGA. The MD cells are shown in brown, the extraglomerular mesangium in blue, the VSMCs in magenta, the renin-producing cells in green, the fibroblasts of the adjacent interstitium in yellow, and the blood vessels in red. Note that both signaling pathways from the MD pass the extraglomerular mesangium, either to reach the VSMCs (I) to regulate filtration or the renin-producing cells (II) to mediate renin secretion.
