Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

Fluorescent probes are described as an expanding assay toolbox that can be combined with larval zebrafish for real-time in vivo monitoring of cell identity, cell fate, and physiology. In the cited review, this use context is framed for organ pathophysiology studies, including the pancreas and islets of Langerhans.

Usefulness & Problems

Why this is useful

This assay approach is useful because larval zebrafish support in vivo microscopy and are presented as well matched to fluorescent probes for dynamic observation of biological states in living animals. The cited evidence specifically supports applications to monitoring cell identity, fate, and physiology during organ pathophysiology studies.

Problem solved

This tool helps address the problem of monitoring cellular states and physiological changes in real time within intact living vertebrate tissue. The supplied evidence places this need in the context of pancreas and islet pathophysiology in zebrafish larvae.

Published Workflows

Objective: Bridge live-cell fluorescence microscopy with electron microscopy so that specific targets can be followed dynamically and then interpreted in higher-resolution ultrastructural context.

Why it works: The review describes complementary strengths: fluorescence microscopy can follow specific targets in living cells, while electron microscopy provides higher resolution and ultrastructural context. New probe development enables these modalities to be connected in a single correlative strategy.

Stages

  1. 1.
    Fluorescence microscopy of specific targets in living cells(functional_characterization)

    This stage captures target-specific and dynamic information that fluorescence microscopy is well suited to provide.

    Selection: Follow specific targets on or in living cells to reveal dynamic localization and/or function.

  2. 2.
    Electron microscopy for higher-resolution structural context(confirmatory_validation)

    This stage addresses the resolution limitation of fluorescence microscopy and places molecules of interest relative to other cellular structures.

    Selection: Use electron microscopy to achieve higher resolution and reveal organelles, membranes, and macromolecules.

Implementation is supported in larval zebrafish in conjunction with in vivo microscopy. The available evidence does not specify construct design, delivery method, expression system, cofactors, or imaging parameters for particular probes.

The supplied evidence is review-level and does not identify specific probe chemistries, fluorescent proteins, target analytes, wavelengths, or quantitative performance metrics. It also does not provide direct evidence for translation-specific readouts despite the provided target process label.
