[The formation of some membrane systems in the thesocyte yolk platelets of a marine demosponge: Suberites domuncula (Olivi) Nardo].
Cellular fragments phagocyted by the thesocytes during the gemmule formation undergo a condensation and rearrangement of their constituent elements before forming a definitive platelet. The membrane excess following this volume reduction is not resorbed but wraps itself round the inclusion to form a membrane series whose function cannot be explained at this time.
