[Interaction radius of aggregating cells of freshwater sponge Ephydatia fluviatilis]. 1982

L A Badenko, and L D Dynkin

A concept of the interaction radius of cells and cell aggregates is presented. Quantitative results of experimental investigations of these characteristics are presented by analyzing the motion of dissociated sponge cells. It is shown that association takes place mainly with cell aggregates of nearly the same size and an essential positive correlation between the interaction radius and their average diameter exists.

UI	MeSH Term	Description	Entries
D011161	Porifera	The phylum of sponges which are sessile, suspension-feeding, multicellular animals that utilize flagellated cells called choanocytes to circulate water. Most are hermaphroditic. They are probably an early evolutionary side branch that gave rise to no other group of animals. Except for about 150 freshwater species, sponges are marine animals. They are a source of ALKALOIDS; STEROLS; and other complex molecules useful in medicine and biological research.	Demospongiae,Sponges (Zoology),Sponge (Zoology),Sponges,Poriferas,Sponge
D002449	Cell Aggregation	The phenomenon by which dissociated cells intermixed in vitro tend to group themselves with cells of their own type.	Aggregation, Cell,Aggregations, Cell,Cell Aggregations
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
