2023
This video describes how to perform microinjections that deliver reagents into live Drosophila embryos. Researchers can use this method to introduce exogenous compounds like nucleic acids and proteins during the early stages of embryo development. The featured protocol demonstrates how to set up and perform the procedure for injection of any soluble reagent–here, a fluorescent protein for live imaging experiments.

Zebrafish (Danio rerio) are an important model organism that is particularly valuable for research in developmental biology. Zebrafish are extremely fertile and can produce hundreds of progeny per week, so it is relatively easy to collect a large number of embryos for high sample numbers. Furthermore, zebrafish undergo rapid development and embryos are transparent, allowing for easy visualization of developmental processes. This video covers the steps required for the collection of newly...

We describe the experimental method to deposit nanostructured oxide thin films by nanosecond Pulsed Laser Deposition (PLD) in the presence of a background gas. By using this method Al-doped ZnO (AZO) films, from compact to hierarchically structured as nano-tree forests, can be deposited.
FAQs
Optical barriers determine how easily microscopy can reveal structures inside an embryo. When pigmentation or other tissue properties obstruct light, internal events become harder to observe; reducing those barriers improves visibility across the specimen. This makes it possible to follow developmental changes in place rather than inferring them only from separated or disrupted samples.
Fluorescent labels make selected cells, tissues, or other structures visible against the surrounding embryo. As labeled features change position or appearance, microscopy can track their behavior through development. This selective visualization helps connect a specific cellular event with larger processes such as tissue organization and organ formation.
Live observation preserves the sequence of events that produces developing tissues and organs. Instead of examining only fixed stages, researchers can follow cell movement and changing structures over time, linking cellular mechanisms with whole-organism outcomes. This temporal perspective is especially useful when development involves coordinated changes that a single endpoint cannot show.
A basic workflow begins with a transparent embryo model, followed by microscopy of its internal development. Researchers may use fluorescent labels to make particular cells or tissues easier to follow, then compare their positions and changes over time. The resulting observations can be organized around cell movement, gene expression, tissue formation, or organ development.
These models support direct study of several developmental processes, including cell movement, gene expression, tissue organization, and organ formation. Because the internal features remain observable during development, researchers can examine how these processes unfold and relate to one another. The approach therefore links microscopic cellular behavior with visible changes across the developing organism.
Transparent embryos allow researchers to visualize developmental events associated with disease-related abnormalities while the specimen develops. Observing cells, tissues, and organs directly can help reveal where an abnormal change appears and how it relates to underlying developmental processes. This provides biological context that complements measurements made after development has been disrupted or completed.
