We present a protocol for capturing the dynamics of zebrafish larval tail fin regeneration on a whole-tissue scale using brightfield-based stereomicroscopy. This technique enables capturing the regeneration dynamics with single cell resolution. This methodology can be adapted to any stereomicroscope equipped with a CCD camera and time-lapse software.

Keeping the microscope optics clean is important for high-quality imaging. Dust, fingerprints, excess immersion oil, or mounting medium on or in a microscope causes reduction in contrast and resolution. DIC is especially sensitive to contamination and scratches on the lens surfaces. This protocol details the procedure for keeping the microscope clean.

The light microscope is a basic tool for the cell biologist, who should have a thorough understanding of how it works, how it should be aligned for different applications, and how it should be maintained as required to obtain maximum image-forming capacity and resolution. The components of the microscope are described in detail here.
FAQs
Image contrast depends on how differently structures absorb or scatter transmitted visible light compared with the surrounding medium. Regions with greater light interaction appear distinct from nearby areas, allowing boundaries and internal organization to be observed. In neural specimens, this contrast supports visual separation of cells, tissue layers, and other anatomical features.
Stains increase contrast by making selected structures more visually distinct from their surroundings. In neuroscience samples, they can reveal nuclei, neuronal cell bodies, axons, or broader tissue organization that may otherwise be difficult to distinguish. This targeted visibility helps connect image features with cellular morphology and the arrangement of neural tissue.
The appearance and arrangement of neuronal cell bodies, axons, nuclei, and tissue layers provide complementary information. Cell shape can indicate morphology, while the distribution of structures shows how tissue is organized. Examining these features together helps researchers assess cellular architecture rather than treating individual stained elements as isolated observations.
Useful specimens include brain sections, cultured neural cells, and stained histological samples. Brain sections support evaluation of tissue architecture, whereas cultured cells allow direct observation of neural-cell morphology. Stained histological preparations provide enhanced visibility of selected structures, making the instrument suitable for varied sample types encountered in neuroscience research and teaching.
Its straightforward operation and broad compatibility make it valuable for routine analysis and instructional settings. Researchers can use it to inspect stained tissue or neural-cell preparations, while students can relate visible cellular features to tissue organization. It is therefore useful when the goal is accessible, repeatable observation of morphology and architecture.
Researchers can compare cellular morphology, tissue architecture, and the visibility or arrangement of stained structures across samples. Differences in neuronal cell bodies, axons, nuclei, or tissue layers may indicate changes associated with an experiment. The resulting observations provide structural evidence for evaluating how neural cells or tissues differ between conditions.
