Extrusomes of different categories in ciliates have been suggested to have different structures and functions. To investigate the characteristics of extrusomes in the hypotrichous ciliate, we examined Architricha indicausing scanning and transmission electron microscopy and electron microscopic enzymo-cytochemistry. Theresults showed that the mature extrusomes were ellipsoidal vesicles with structureless cavities on their anteriorparts and arranged in rows beneath the pellicle; the extruded structures of extrusomes were cyathiform and canremain outside of the cell surface after extrusion. These findings differ distinctly from that of previouslyreported extrusomes in other ciliates and thus suggest a new type of extrusomes. These organelles originatedfrom endoplasmic reticulum in the deeper part of the cytoplasm, underwent a serious of development,gradually migrated to the cortical cytoplasm and finally positioned in their functional areas. In contrast withlower forms of ciliates, density, arrangement, and localization of extrusomes in A. indica showed obviousdifferences between the ventral and dorsal surface of cells. This may be in some way related to thedifferentiation of the dorsoventral cortex, and functional ciliature happened to the hypotrichous ciliates. Inaddition, the extrusomes may perform protective or defensive function, which associates with the activity ofmitochondria and contributes to the pellicle retrieval or renewal.
