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.

FAQs
Separating the outer cortex from the inner medulla helps investigators organize what they see within the specimen. This distinction provides a structural framework for relating visible ovarian regions to follicle development and reproductive function. It is therefore useful when interpreting anatomy during biological study, rather than treating each feature as an isolated observation.
Follicles and oocytes provide visible points of connection between ovarian structure and reproductive biology. Examining them can support study of follicle development and help relate cellular reproductive components to the larger anatomy of the organ. Their appearance is especially informative when the goal is to connect gross observations with ovarian function or developmental changes.
By exposing internal regions and reproductive structures, Ovary Dissection allows specimens from different life stages or experimental conditions to be examined using comparable anatomical features. Investigators can then document differences in visible ovarian organization, follicles, or other structures. This approach supports developmental studies and investigations of how ovarian anatomy changes over time or under defined conditions.
The specimen must first be positioned so its internal structures can be accessed, after which fine instruments are used to make controlled cuts. This sequence exposes the cortex, medulla, follicles, oocytes, and other visible features for examination. Careful positioning and cutting are important because the quality of the exposed anatomy determines what can be observed.
Preserved tissues are prepared for microscopy when the investigation requires examination beyond the features visible during direct dissection. Microscopic preparation complements the exposed gross anatomy by making preserved tissue available for closer study. Together, these approaches help link the organ's overall structure with reproductive features and support biological teaching or research.
This technique supports comparative anatomy, developmental studies, and investigations of reproductive cycles. Comparing specimens can reveal differences in ovarian organization, while developmental work can track structural changes across life stages. In experimental research, examination of visible regions and reproductive structures can help evaluate how ovarian anatomy changes under particular conditions.
