- Resumo: During oogenesis the germ cells of bees remain connected by intercellular bridges. The bridges connecting the germ cells are the result of incomplete cytokinesis during the proliferating phase of the cystoblast. The cystocytes that result from such proliferation remain linked together and constitute a cyst. The bridges that interconnect these cells provide a way for the distribution of the substances that determine which one of the cells would become the oocyte and, latter, for the transport of the products synthesized by the remaining cells, known in meroistic ovaries as nurse cells, into the oocyte. Elements of the cytoskeleton sustain the bridges and orientate the flux of substances through them. In the present work, a study of the distribution of these elements in the ovary germarium of Scaptotrigona postica and Apis mellifera was conducted using the techniques of transmission electron microscopy and confocal microscopy. It was possible to observe that the cystocytes are linked by short and wide bridges, reinforced by actin rings and which present two bundles of thick filaments of unknown nature that extend throughout the width of the bridge. A large amount of tubulin with irregular distribution can be observed in the cytoplasm. Our results show not only the distribution but also the dynamics of the cytoskeleton during the proliferation of the cystocytes
