Three-dimensional exploration of the chicken embryo, a comparative study of light sheet and histological visualisation.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ultramicroscopy has offered new avenues into the visualisation of tissues within animal models, providing three-dimensional visualisation through the use of light sheet fluorescence microscopy. This study aimed to develop and apply an optical tissue clearing method to investigate the application of light sheet fluorescence microscopy to image late-stage chicken embryos, and compare anatomical visualisation to traditional histological staining. Seventeen-day old specific pathogen free embryos were collected, fixed, and sectioned. Haematoxylin and eosin stained sections were prepared for histology, while light sheet imaging required the tissues to be optically clear. For this, an ethyl cinnamate-based method was utilised, allowing for acquisition of clear, unobstructed three-dimensional images of significant organ structures and systems using only autofluorescence. The use of established histological techniques provided anatomical mapping of structures between familiar histology images and the three-dimensional light sheet images. Rendering of organs using light sheet imaging provided contextual insights into the surrounding tissues and physiological architecture of major organ structures and systems. This was most apparent through the identification of the pulmonary vein and rendering of a volumetric projection of the vasculature branching within the lung and the subsequent merging of vasculature into the left side of the heart. Overall, the visualisation of the chicken embryo was enhanced by combining traditional histology with the information gained by three-dimensional light sheet fluorescence microscopy.
