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 retina is a crystal-like lattice composed of a small number of cell types that are generated in a stereotyped manner 1. Its amenability to sophisticated genetic analysis allows the study of complex developmental programs. This protocol describes dissections and immunohistochemistry of retinas at three discrete developmental stages, with a focus on photoreceptor differentiation.
FAQs
Immobilization provides the stability needed to work under a stereomicroscope while using fine instruments to open the larval body wall. This controlled access helps the researcher expose internal structures while maintaining the anatomical organization needed for examination. The resulting preparation supports closer analysis of organ structure and development than an intact specimen viewed only from the outside.
Removing surrounding tissues selectively exposes the target organ or tissue while helping preserve its structure for subsequent examination. This balance is important because the preparation may be used for imaging, staining, or further analysis. Careful isolation therefore connects the physical anatomy revealed during dissection with cellular or tissue-level observations made afterward.
Larval dissection provides direct access to internal anatomy, allowing researchers to examine how organs form, grow, and become organized. It can reveal tissue-level differences associated with genetic or environmental changes that may not be evident from whole-organism observations alone. These findings complement broader phenotypic measurements with direct structural evidence.
A typical workflow begins by immobilizing the larva under a stereomicroscope. Fine instruments are then used to open the body wall, expose internal structures, and remove surrounding tissues from the target. After isolation, the structure can be prepared for imaging, staining, or further analysis. The sequence emphasizes access while preserving material for downstream examination.
The procedure specifically relies on a stereomicroscope for visual guidance and fine instruments for opening the body wall and removing surrounding tissues. The isolated structures may then be handled for imaging, staining, or additional analysis. These components support both precise anatomical exposure and the preservation of specimens for different forms of biological investigation.
Researchers apply the technique to developmental biology, anatomy, gene-expression studies, and investigations of neural or muscular organization. It can also help examine disease-related phenotypes by providing direct evidence from internal tissues. Because the method links visible structure with development and biological change, it complements observations made at the whole-organism level.
