Pseudopod movement is more complex than most would expect. It relies on biomolecular reactions, cell deformation and the motion of both cytoplasm and extracellular fluid.

Current descriptions of eukaryotic chemotaxis focus on how extracellular signals (chemoattractants) cause new pseudopods to form. However, reinterpretation of recent data suggests a 'pseudopod ...

Membranes required for pseudopod extension are provided by insertion of recycling endosome membranes enriched in the SNARE VAMP3 (light blue) at the site of phagocytosis. Full size image.

Pseudopod movement is more complex than most would expect. It relies on biomolecular reactions, cell deformation and the motion of both cytoplasm and extracellular fluid.

It’s not clear how D. discoideum knows where it’s been. Amoebas move by extending protuberances known as pseudopods. One possibility, Li says, is that forming a pseudopod leaves a temporary ...
