Cell death in ovarian chambers of Drosophila melanogaster
F Giorgi et al. J Embryol Exp Morphol. 1976 Jun.
Abstract
An ultrastructural analysis has been made of certain ovarian chambers undergoing abnormal development. The earliest morphological change in these chambers consists of the alteration of the nuclear material which is then followed by engulfment of portions of the nurse cell cytoplasm, including the nuclear fragments, into the overlying follicle cells. The continuation of this process leads to the progressive disappearance of nurse cells with the concomitant formation of huge dense vacuoles in the follicle layer. The morphological features described in the present investigation are similar to those found in other tissues and interpreted as leading to cell death. It is suggested that certain ovarian chambers undergo cell death as a result of the incapability of furthering their development. The role played by cell death in oogenesis is also discussed on the basis of the current literature.
