Apoptosis of nurse cells at the late stages of oogenesis of Drosophila melanogaster.

Abstract excerpt

In Drosophila a remarkable feature of oogenesis is the regression of the nurse cells after dumping their cytoplasmic contents into the oocyte. We have studied the nature of this process at the late stages of egg chamber development. In egg chambers DAPI staining shows highly condensed chromatin from stage 12 and TUNEL labelling shows DNA fragmentation up to stage 14. Gel electrophoresis of the end-labelled DNA,...
