To determine whether extracellular surface marker movement and intracellular organelle transport in reticulopodial networks are governed by the same motile machinery.
Applied polystyrene microspheres to the reticulopodial networks of foraminiferans Allogromia sp. (strain NF) and A. laticollaris.
Used electron microscopy to characterize microsphere adhesion to the reticulopodial surface glycocalyx.
Tracked and analyzed microsphere motility relative to pseudopod extension, retraction, and underlying organelle motion using videomicroscopy.
Polystyrene microspheres adhered directly to the surface glycocalyx and exhibited bidirectional, saltatory movement at speeds up to 11 µm/s, independent of pseudopod extension or withdrawal.
Surface microspheres displayed motile characteristics identical to those of saltating intracellular organelles across varying marker sizes and surface properties.
Surface-bound microspheres were observed to be transiently linked in coordinated motion with underlying intracellular organelles.
