How niches and stem cells form during development is an important question with practical implications. In the Drosophila ovary, germ line stem cells and their somatic niches form during larval development. This video demonstrates how to dissect, stain and mount female gonads from late third instar (LL3) Drosophila larvae.

The Drosophila ovary is an excellent model system for studying stem cell niche development. Though methods for dissecting larval and adult ovaries have been published, pupal ovary dissections require different techniques that have not been published in detail. Here we outline a protocol for dissecting, staining, and mounting pupal ovaries.

Drosophila oogenesis continues to be exceptionally useful in the study of mitochondrial proliferation and inheritance. This manuscript describes a detailed protocol used to label the replicating mitochondrial DNA (mtDNA) in Drosophila adult ovaries with 5-ethynyl-2´-deoxyuridine (EdU), which facilitates uncovering mechanisms associated with mitochondrial inheritance that were previously debatable.
FAQs
Keeping the egg chambers connected maintains the ovary’s ordered tissue context rather than reducing the sample to isolated cells. That organization lets investigators examine developmental progression, cell differentiation, and tissue structure across successive stages. Preserving this arrangement is especially useful when microscopy is intended to relate local organization to oogenesis or stem cell maintenance.
The preparation supports analysis at several biological levels. Microscopy can reveal tissue organization and developmental features, while fixation and staining make the isolated ovaries suitable for visual examination. Molecular analysis can then investigate gene function and developmental signaling. Together, these readouts connect visible changes in egg chambers with underlying reproductive and cellular processes.
Physiological saline provides the medium in which the abdomen is opened and the ovaries are removed, while the stereomicroscope supplies the magnification needed to locate and manipulate the tissue. Gentle handling matters because the preparation is intended to retain paired ovaries and their developing egg chambers. These conditions support a usable sample for later analysis.
An overview workflow begins by immobilizing an adult female fly, placing it under a stereomicroscope, opening the abdomen in physiological saline, and gently extracting the paired ovaries. The key procedural objective is not simply removal, but recovery of intact tissue with its chain of developing egg chambers. The isolated material can then proceed to downstream preparation.
After isolation, the ovaries may be fixed, stained, or cultured, depending on the intended analysis. Fixation and staining support microscopy, whereas culture provides a way to examine the dissected tissue under experimental conditions. Molecular analysis is another downstream option. Selecting among these treatments determines whether the study emphasizes structure, organization, or gene-related processes.
Biologists use this preparation to connect ovarian structure with developmental and genetic questions. It can support studies of oogenesis, stem cell maintenance, cell differentiation, and tissue organization, as well as investigations of gene function and developmental signaling. Because Drosophila melanogaster serves as a model organism, the dissection also contributes to research on reproductive biology and disease-related cellular processes.
