Nematodes
Nematodes are unsegmented, multicellular invertebrates. Most are worm-like and thread-shaped. Among them, Caenorhabditis elegans (C. elegans) plays a vital role in biological research. It was the first animal to have its genome fully sequenced. About 40% of its approximately 20,000 genes are homologous to human genes. In addition, C. elegans has a short life cycle, high reproductive capacity, complete developmental and anatomical characteristics, as well as complex genetic traits. Therefore, it is an important model organism for biological research.
Applications of Microimaging in Nematodes
Nematodes are fully transparent and small in size, so they can only be observed with the help of microimaging technology. Brightfield or oblique illumination can be used for the culture and selection of nematodes. Hoffmann modulation contrast enables microinjection operations on nematodes. Finally, fluorescence labeling and fluorescence observation techniques allow for research and observation at a finer level of detail.
Challenges of Microimaging in Nematodes
Nematode culture and selection require sufficient working space and three-dimensional perception, which can be met using a stereomicroscope. Although conventional stereomicroscopes allow overview of the overall morphology, details of internal structures rely on high-power biological microscopes (upright or inverted), which imposes high requirements on the optical performance and operational precision of the microscope. In addition, characteristics such as variable transparency and high mobility of nematodes increase imaging difficulty, requiring specific techniques such as fluorescent labeling and fixation for assisted observation.
