Abstract/OtherAbstract:
Follicle cell morphogenesis during Rhodnius oogenesis involves extensive changes in lateral follicle cell shape, creating a patent epithelium. Cytoskeletal elements are involved in this cell shape change as assessed by investigating the relative abundance, orientation and dynamics of the follicle cell microtubule and microfilament cytoskeleton. Anti-tubulin immunofluorescence and transmission electron microscopy revealed the cytoskeletal organization from pre-follicular to post-vitellogenic follicle stages. A well-developed cylindrical arrangement of longitudinally orientated microtubules is present beneath the plasmalemma of the non-patent pre-vitellogenic and apical vitellogenic follicle cells. In contrast patent lateral vitellogenic follicle cells contain a dispersed distribution of microtubules in both longitudinal and cross-sectional planes. Prominent microfilament bands are not abundant in the pre-vitellogenic or apical vitellogenic follicle cells. The lateral vitellogenic follicle cells do however contain a prominent band of microfilaments in the subplasmalemmal area and in the projections connecting to adjacent cells and the apical microvilli. The changes in cytoskeletal arrangement in lateral follicle cells during vitellogenesis emphasize a third essential component, in addition to juvenile hormone stimulated [NA(+)K(+)] ATPase cell shrinkage, and cell junctional modulation, for the formation of a patent follicle cell epithelium in Rhodnius.
