title: In vivo cultivation of Echinococcus multilocularis protoscoleces in micropore chambers.
abstract: Micropore chambers containing unevaginated protoscoleces of E. multilocularis were implanted into the peritoneal cavity of AKR mice. Transformation from protoscoleces to fertile multivesicular cysts was obtained after 210 days. Ultrastructural observations of these morphological transformations indicate that a phase of histogenesis follows a phase of dedifferentiation. This morphogenetic process raises the question of the origin of new cell populations. The results reveal the potential role of protoscoleces in secondary echinococcosis and the value of this experimental model for further studies on the larval development.
