From: Combined nanometric and phylogenetic analysis of unique endocytic compartments in Giardia lamblia sheds light on the evolution of endocytosis in Metamonada

Time course on fluorescent dextran uptake in selected metamonada and discoba specimens: G. lamblia, S. vortens, S. salmonicida and T. foetus after 30 min. A PV/PECs in G. lamblia start acquiring external material right after 5 min of incubation with dextran. Over 30 min of dextran incubation, the endocytic marker does not leave PV/PECs. In B S. vortens, C S. salmonicida and D T. foetus, dextran is up taken in the small vesicles. In S. vortens, these small vesicles tend to agglomerate at the centre of the cell while in S. salmonicida, these vesicles seem to stay peripheral. In T. foetus, vesicles bearing dextran from the periphery of the cell also migrate to the interior of the cell. All scale bars: 5 μm
