Antistrophic pseudopodia of the collective amoeba Polysphondylium violaceum

Experimental Cell Research, 1965
Abstract In a sufficiently shallow water layer, branch pseudopods, or “pseudodigits”, may have little or no contact with the substratum, while the main cell masses are flattened on it; and each cell in a chain of aggregating cells may have one or more hooked pseudodigits applied to the side of the cell ahead.

A new family of amoebae with fine pseudopodia

Zoological Journal of the Linnean Society, 1975
A new family, the Echinamoebidae, is proposed within the order Amoebida (Protozoa, Sarcodina) for amoebae producing finely-pointed, non-anastomosing pseudopodia. Within this family two new genera, Echinamoeba and Stachyamoeba, are defined and two new species of edaphic origin described.

Pseudopodia and Adhesion Structures

2011
Pseudopodia, the cytoplasmic outgrowths of lamellar shape (lamellipodia, ruffles), filamentous shape (filopodia), or spherical shape (blebs), are the “driving organs” formed by cells to spread and migrate, and also can have sensory or metabolic ­functions.

Exocytosis and nerve terminal pseudopodia.

Federation proceedings, 1982
When exocytosis of synaptic vesicles is accompanied by the accumulation of vesicle membrane in the nerve terminal membrane, the geometric shape of the terminal must alter. The details of these rearrangements vary with the anatomical site; this laboratory has reported on the responses of abutted nerve terminals in the electric ray electric organ.

Phagocytic funnel-like pseudopodia in lectin-treated gastropod hemocytes

Journal of Invertebrate Pathology, 1980
L. R. Renwrantz, T. Yoshino, T. Cheng, and K. Auld (Zoo/. Jb. Physiol. 83, l12, 1979) have described a phagocytic mechanism of Crassostrea virginica (Mollusca: Pelecypoda) hemocytes by which rat erythrocytes could be internalized through a single funnel-shaped pseudopodium. These structures were similar to those seen in vertebrate leukocytes (J.

Pseudopodia and intracytoplasmic displacements of the collective amoebae dictyosteliidae

Experimental Cell Research, 1965
Abstract The contractile vacuoles tend to occupy a fixed position in the cell, but noncontractile vacuoles make extensive saltatory excursions throughout the granuloplasm essentially unrelated to and much more rapid than the cell's locomotion. Other components of the granuloplasm are also in continual turmoil.

Revisiting secretory granule fusion at vesicular pseudopodia

Journal of Cell Science
ABSTRACT Secretory granules are specialized vesicles that package large amounts of cargo, such as hormones, enzymes and mucous. They are typically stored intracellularly until an extracellular signal initiates exocytosis, characterized by fusion between the secretory vesicles and the plasma membrane, resulting in cargo release to the ...

Unequal distribution of membrane components between pseudopodia and cell bodies of platelets

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1990
Platelet pseudopodia were compared to platelet cell bodies with respect to their lipid composition, fatty acid distribution and protein composition. The methodology for producing pseudopodial preparations of platelets stimulated with thrombin, ADP or calcium ionophore was established.

Movement of surface markers along the pinocytotic pseudopodia ofAmoeba proteus

Protoplasma, 1994
The movement of latex beads over pinocytotic pseudopodia produced byAmoeba proteus was recorded in the presence of 117.65 mM EGTA as an inducer of pinocytosis. The results show that all particles flow in the direction of pseudopodial growth, with a slightly higher velocity than the advancing frontal edge.

Pseudopodia of capillary endothelium in ocular tissues.

Japanese journal of ophthalmology, 1990
The frequencies of pseudopodia projecting from capillaries of various parts of the eye were observed in 16 human eyes with a transmission electron microscope. The pseudopodia were found mainly projecting from the choriocapillaris and rarely seen in the retina, iris or ciliary body.
