Abstract

Drosophila variable nurse cells (vnc) egg chamber with a binucleate oocyte resulting from an extra nuclear division after oocyte specification. Nuclear lamin staining (green) allows visualization of oocyte nuclei that have a much lower DNA content than polyploid nurse cell nuclei (blue). F-actin (red) reveals cell outlines and ring canals that link nurse cell and oocyte cytoplasm. From Warrior et al., Developmental Dynamics 239:2813–2827, 2010.
