Electron microscopical characterization of sponge aggregation factors.
Aggregation factors, purified from 14 sponges which belong to the classes Tetraxonida and Cornacuspongia, Were visualized electron microscopically. Two types of basic structural forms were detected; first, circular structures from the species Ancorina cerebrum, Mycale massa, Hemimycale columella, Crella rosea, Clathria coralloides, Axinella cannabina, Pellina semitubulosa, Ircinia muscarum, Hippospongia communis, Verongia aerophoba and second, rod-like structures from Tethya lyncurium, Tedania anhelans, Hymeniacidon sanguinea, Dysidea tupha. In most of the cases the structures carry side chains.
