The Drosophila egg chamber is an excellent model for studying the mechanisms of mRNA localization. In order to capture the dynamic events that underpin the processes of localization, rapid high resolution imaging of live tissue is required. Here, we present a protocol for dissection and imaging of live samples with minimal disruption.

This protocol describes three Drosophila preparations: 1) adult brain dissection, 2) adult retina dissection and 3) developing eye disc- brain complexes dissection. Emphasis is laid on special preparation techniques and conditions for live imaging, although all preparations can be used for fixed tissue immunohistochemistry.

A method is described for the preparation of single living photoreceptor cells from different vertebrate species for fluorescence imaging. The method can be used to image the fluorescence of endogenous fluorophores, such as NADH or vitamin A, or that of exogenously added fluorescent dyes sensitive to Ca2+ or other factors.
FAQs
Specimen selection determines whether the sample can remain healthy and optically accessible throughout observation. Researchers must consider the type of living material, its culture requirements, and the biological activity they need to monitor. A suitable specimen supports normal behavior during imaging, making observations of processes such as division, migration, development, or intracellular transport more reliable.
These conditions help preserve the physiological state of the specimen while microscopy takes place. Temperature supports appropriate biological activity, gas exchange maintains the surrounding culture environment, and humidity helps prevent damaging changes during observation. If these factors are poorly controlled, imaging-related stress can alter normal behavior and weaken the accuracy of time-lapse conclusions.
Mounting must hold the specimen securely without preventing the biological activity being studied. It also establishes a clear optical path so the microscope can resolve relevant structures or events. Effective mounting reduces movement that would otherwise blur sequential images, while preserving access to the living sample for observations over time.
Light exposure can contribute to stress during microscopy, so preparation should limit it while still providing enough illumination for observation. This balance helps preserve normal biological activity across a time-lapse sequence. Managing exposure is especially important when the goal is to interpret dynamic behavior, because imaging conditions should not become the cause of the observed change.
A practical workflow begins by selecting a specimen suited to the biological question, then establishing appropriate culture conditions. The sample is mounted to provide optical access and limit movement, while temperature, gas exchange, humidity, and light exposure are controlled. These steps work together to maintain health and create consistent conditions for microscopy.
It is particularly valuable when researchers need to follow biological events as they unfold rather than examine only a fixed endpoint. Time-lapse observations can reveal cell division, migration, development, and intracellular transport. Maintaining the specimen during imaging allows these processes to be viewed in relation to their timing and changing spatial organization.
Consistent preparation improves image quality and experimental reproducibility by reducing avoidable variation in specimen condition, movement, and optical access. It also helps distinguish genuine biological behavior from changes caused by microscopy-related stress. As a result, researchers can draw more accurate conclusions about living systems and compare observations across imaging sessions with greater confidence.
