(2) Invaginating mesodermal cells of the lateral and ventral parts also form pseudopodia, and are in contact with the blastocoelic wall.
(3) Scanning and transmission electron microscopy revealed that promastigotes of the invasive species entered fibroblasts flagellum-end first through pseudopodia-like structures formed on the host cell surface, reminiscent of "induced phagocytosis."
(4) Upon contact with the interface, they project numerous lamellipodia and pseudopodia.
(5) When explants of neurofibroma tissue were cultured, macrophage-like cells with pseudopodia migrated out first, and later took on a slender fusiform shape.
(6) A new model for clot contraction is proposed, based on the rigidity of the long spiky pseudopodia and on the motile properties of platelets.
(7) In addition to moderate and severe vacuole, granule, and pseudopodia formation, all contractile activity was inhibited as early as 2 h after exposure to the intermediate concentration of 1 x 10(-4) M amitriptyline.
(8) Ultrastructurally the thyroid epithelial cells show pseudopodia protruding into the lumen at zero, two and six hours after birth.
(9) Other cytoplasmic elements of the myoastrocytes were deeply indented nuclei, endoplasmic reticulum and pseudopodia with large cytoplasm.
(10) They gradually displayed active membrane pseudopodia, thorn-like processes and petal-like ruffles after 2 h to 4 h of cultivation.
(11) This effect was directly related to the development of pseudopodia and may reflect alteration of surface features of the rod outer segment (ROS)-RPE interface related to phagocytosis.
(12) Electron microscopic analysis of livers at reflow revealed Kupffer cells with numerous pseudopodia and lamellapodia, reflecting an activated state.
(13) Whereas the intramembranous particle number in glial pseudopodia is only slightly lower than in their perikaryal plasmalemma, the number of particles in outgrowing axons increases about eightfold from the periphery towards the perikaryon.
(14) alpha-tocopherol-enriched platelets that adhered to adhesive surfaces failed to show the usual long thin pseudopodia but exhibited short, rounded, blunt projections.
(15) Under unfavorable conditions for growth, haploid myxoamoebae of Physarum polycephalum retracted their pseudopodia and changed their cell shape into disk-like form, after which they constructed the cell walls to form microcysts.
(16) This inhibition is accompanied by a cessation of the movement of ruffles and pseudopodia on the surface of the cells and the formation of blebs which arise from the cell's surface.
(17) Pseudopodia counts were made on electron micrographs, and calculated as a percentage of the NSG population.
(18) Calcium triggers the actin-myosin interaction and the developing force, possibly together with a local increase of the cation concentration, may cause the collapse of the microtubular ring and its reappearance in the forming long pseudopodia.
(19) The entire cell surface arrears to be capable of fusion since fusion occurs in regions where pseudopodia make contact with each other or with a neighbouring cell body and also in areas where cells are in contact along their entire periphery.
(20) Amoebae were seen in the process of detaching portions of cytoplasm from whole ME cells by means of distinctive ingesting pseudopodia, and fragments of mammalian-cell cytoplasm were identified within the food vacuoles of trophozoites.
Radiolarian
Definition:
(a.) Of or pertaining to the Radiolaria.
(n.) One of the Radiolaria.
Example Sentences:
(1) There are various types of photoproteins: the photoproteins of coelenterates, ctenophores and radiolarians require Ca2+ to trigger their luminescence; the photoproteins of the bivalve Pholas and of the scale worm appear to involve superoxide radicals and O2 in their light-emitting reactions; the photoprotein of euphausiid shrimps emits light only in the presence of a special fluorescent compound; the photoprotein of the millipede Luminodesmus, the only known example of terrestrial origin, requires ATP and Mg2+ to emit light.
(2) However, colonies maintained in the dark have a decline in number of zooxanthellae and light microscopic examination shows they are being drawn into the ectoplasm of the radiolarian cells.
(3) Collozoum inerme (Müller) is a colonial Radiolarian containing numerous cells bound in a common gelatinous matrix.
(4) T. nucleata is a skeletonless, single-celled radiolarian commonly found in ocean surface water.
