Title: Induction of lobopodia and lamellipodia in a filopodial organism (Vampyrella lateritia)
Abstract: The normally filopodial motor system of Vampyrella lateritia was modified by chemical agents that promote cell adhesion and spreading and by mechanical stimuli. Large lobopodia arose by cell surface blebbing between the filopodia. The cortical cytoskeletal layers periodically detached from the plasma membrane at the growing tips of lobopodia and moved backwards. Combined chemical and mechanical stimuli sometimes resulted in the development of lamellipodia, which were either circular as characteristic of cell spreading, or intensely expanded in one direction as usual in locomotion. Lamellipodia arise from filopodia by their swelling and fusion. After retraction they leave behind a reconstructed filopodial system. In general, in Vampyrella as in some other motile cells, lobopodia arise and function independently of filopodia, whereas the lamellipodia and filopodia are related by their origin and may be transformed one into another.
