Nephrocytes in lobster (II): reconstruction images of foot processes and ridge-like prominences (RLPs). Reconstruction images of two adjacent nephrocytes (green and purple). All images show the basal surface of cells. (a) Numerous fine long foot processes (whitish-purple) protruded from a massive part via the RLP (yellowish-purple). (b–b″, c, c′) RLP was partially retracted (arrowheads in a, b″). Thus, foot processes were closely apposed across the retracted RLP (arrows in b, b′) or connected to form an autocellular junction (arrowheads in c, c′). Scale bars, 100 nm. The reconstructed nephrocyte (a) is also shown in Supplementary Movies S9 and S10
