Autophagy is a ubiquitous process that enables cells to degrade and recycle proteins and organelles. We apply advanced fluorescence microscopy to visualize and quantify the small, but essential, physical changes associated with the induction of autophagy, including the formation and distribution of autophagosomes and lysosomes, and their fusion into autolysosomes.

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.

Accurate analysis of multidimensional microscopy data requires complex workflows. This article demonstrates how to use the software Cell-ACDC. It leverages state-of-the-art AI-driven models for segmentation, tracking, cell pedigree analysis, and quantification of microscopy data. Crucially, it complements these models with an innovative framework for semi-automated correction of the models' output.
FAQs
Contrast arises when different parts of a specimen absorb or scatter transmitted white light to different degrees. These variations make cellular, tissue, or microbial features appear distinct against their surroundings. Interpreting the resulting light differences helps researchers evaluate structural organization and recognize morphological variation in biological samples.
Staining increases the visibility of cells, tissues, and microorganisms that may otherwise provide little contrast in transmitted light. By enhancing differences within the specimen, it makes structural features easier to distinguish during visual examination. This is particularly useful when analyzing histological sections or other samples whose natural appearance is difficult to resolve.
The method can reveal differences in biological structure and organization that become visible through light absorption, scattering, or staining. Researchers can examine cell and tissue morphology, inspect microorganisms, and evaluate the appearance of prepared histological sections. These observations support sample characterization by linking visible features with the organization of the specimen.
A basic workflow uses transmitted white-light illumination, places the biological specimen in the microscope’s optical path, and focuses the microscope to form a clear image. The sample can then be visually examined for morphology or organization. When natural contrast is insufficient, staining may be used before evaluating the image.
Brightfield Microscopy Analysis is useful when researchers need a direct visual assessment of cells, tissues, or microorganisms. It supports routine examination, sample characterization, and teaching, while also serving laboratory diagnostic work. Its accessible instrumentation makes it practical for repeated observations and for evaluating stained histological material.
Brightfield images can provide a visual basis for estimating cell abundance and documenting morphological features. Researchers may examine the image output to compare samples, assess organization, or record differences in visible structure. When paired with quantitative image analysis, the method extends beyond description by supporting measurement-based characterization of biological specimens.
In studies of microbial growth, researchers can use brightfield images to observe microorganisms and estimate their abundance. The transmitted-light image provides direct visual information about the sample, while staining may improve visibility when organisms are difficult to distinguish. These observations help characterize changes in microbial samples during biological analysis.
