Fig. 1. Two series of pictures of the contractile vacuole complex-derived membrane
vesicles obtained from two different P. multimicronucleatum cells
(Ai, Bi). (Aii, Aiii, Bii) The IV relationships for different
membrane vesicles in Ai and Bi. Ai, Bi reveal the portion of the contractile
vacuole complex from which each vesicle is derived. n, a microneedle used for
incision of the cell or for preventing fusion of the membrane vesicles; p,
suction pipette for removing solution around the cell; e, patch-clamp
electrode. Scale bars, 50 µm. See the text for details.
