NC nuclear elimination in stage 10B egg chambers. Summary diagram illustrating the principal features of nuclear elimination. Subsequent to the anterodorsal localization of the GV (purple) in close proximity to the border cells (yellow; a), RCs (green) migrate into the oocyte and a pore forms that directly connects the oocyte with adjacent NCs (b), NCN translocate into the oocyte (c), and the GV migrates posteriorly (d). The NCN are absent from egg chambers in which the RCs have returned to the interface of the oocyte with enucleated NCs.
