Animals, Coelomocyte Counting, and Bacterial Challenge
neumayeri has been approached in this study by measuring an increase in coelomocyte expression 24 h after bacterial stimulation (not only a constitutive expression).
Coelomocytes scarce, flat, oval, 14-20 um long and 9 [micro]m wide, granulate, with nucleus.
Coelomocytes usually not observed, but numerous in some specimens (Fig.
The red color is due to the presence of hemoglobin containing coelomocytes
(RBCs) present in the water vascular system (Christensen 1999).
Plasminogen plays an important role in early regeneration and wound repair in vertebrates, and there are similarities between echinoderm coelomocytes
and the immune systems of vertebrates.
Evolution of the acute phase response: iron release by echinoderm (Asterias forbesi) coelomocytes
, and cloning of an echinoderm ferritin molecule.
Postmortem dissections of these urchins revealed large numbers of red coelomocytes
in the coelomic fluid.
1994) demonstrated the amplification of 3'-UTRs from sea urchin (Strongylocentrotus purpuratus) coelomocytes
and human endothelial cell RNA using a primer containing the "ATTTA" motif and an oligo d(T) primer.
Autogeneic but not allogeneic earthworm effector coelomocytes
kill the mammalian tumor cell target K562.
Bivalve amebocytes, also called coelomocytes
, hemocytes, leukocytes, phagocytes, and blood-cells, are considered key to internal defense because of their ability to phagocytose, encapsulate, and degrade foreign material, including parasites and pathogens (Takatsuki 1934, Wagge 1955, Bang 1973, Narain 1973, Cheng 1975, 1981, 1984, Fisher 1986, Feng 1988, Chu 1988, Chu 2000).
