Abstract: | The establishment and reorganization of intercellular bridges during larval-adult ovarian differentiation is the basis of the syncytial nature of the adult hemipteran telotrophic ovary. The formation, in the late differentiation phase, of groups of closely arranged nurse cell nuclei occupying a common cytoplasm results from membrane fusions. Oocyte-oocyte intercellular bridge systems later are modified to form the trophic cords. The trophic core, which undergoes a restructuring during the late differentiation phase, mediates nurse cell-oocyte interactions in this system. Material, transported to and accumulated by late differentiation phase pre-vitellogenic oocytes, originates from trophic core restructuring and zone III nurse cell production. |
