The zebrafish embryo is an excellent model for developmental biology research. During embryogenesis, zebrafish develop with a yolk mass, which presents three-dimensional challenges for sample observation and analysis. This protocol describes how to create two-dimensional flat mount preparations of whole mount in situ (WISH) stained zebrafish embryo specimens.

The interaction and sedimentation of the clay and bacterial cells within the marine realm, observed in natural environments, can be best investigated in a controlled lab environment. Here, we describe a detailed protocol, which outlines a novel method for measuring the sedimentation rate of clay and cyanobacterial floccules.

The branchial skeleton, including gill rakers, pharyngeal teeth, and branchial bones, serves as the primary site of food processing in most fish. Here we describe a protocol to dissect and flat-mount this internal skeleton in threespine sticklebacks. This method is also applicable to a variety of other fish species.

Whole-Mount In Situ Hybridization

Whole-mount in situ hybridization (WMISH) is a common technique used for visualizing the location of expressed RNAs in embryos. In this process, synthetically produced RNA probes are first complementarily bound, or "hybridized," to the transcripts of target genes. Immunohistochemistry or fluorescence is then used to detect these RNA hybrids, revealing spatial and temporal patterns of gene expression. Unlike traditional in situ hybridization techniques, which require thin tissue sections whose...
FAQs
Modeling clay mounting supports reproducibility by limiting unwanted movement while preserving a chosen specimen orientation. That stability helps the same anatomical or cellular region remain presented to the imaging system or manipulation tool, reducing positioning differences between observations. In cancer studies, this is especially useful when researchers compare tumor structure, cellular behavior, or treatment responses across samples or experimental conditions.
The clay’s pliability allows support to be formed around or beneath a specimen rather than forcing the sample into a fixed arrangement. This provides mechanical restraint while keeping the target surface exposed to microscopes, probes, or surgical tools. The balance matters because excessive obstruction could limit access, whereas insufficient shaping may fail to maintain the desired orientation during observation or manipulation.
Mounting quality depends on how the support is shaped relative to the specimen and the surface that must remain accessible. Researchers must preserve the intended orientation, stabilize the sample sufficiently for imaging or manipulation, and avoid covering the target area. These considerations influence whether observations consistently capture comparable regions and whether measurements can be reproduced across preparations.
A basic workflow begins by shaping pliable clay around or beneath the biological specimen, then positioning the sample in the intended orientation. The support is adjusted to maintain gentle mechanical restraint while leaving the target surface accessible. Before imaging or manipulation, the preparation should be checked for stable positioning and unobstructed access, because both conditions determine whether the planned observation can proceed consistently.
In cancer research, the technique can be applied to tumor samples, model organisms, and tissue preparations that must remain consistently positioned during microscopy or comparative experiments. It is relevant when investigators examine tumor structure, follow cellular behavior, or compare treatment responses. By standardizing presentation of the specimen, mounting helps distinguish biological differences from changes caused simply by sample orientation.
The immediate outcomes are more stable specimen presentation, improved image quality, and measurements that are easier to reproduce. These benefits do not themselves reveal a tumor mechanism or treatment effect; they strengthen the experimental basis for interpreting those findings. Consistent mounting therefore supports comparisons among preparations by making positional variation less likely to account for apparent differences.
