Caenorhabditis elegans is a model organism widely used for studying biological processes. Its transparency and small size make it ideal for imaging tissues, cells, and subcellular structures. Traditional flat agar pads for imaging C. elegans limit control over the animal's orientation, restricting views primarily to lateral perspectives. This limitation complicates the visualization of dorsal-ventral structures and reduces image clarity, especially in older animals with increased pigmentation and larger diameters. To overcome these challenges, we developed channeled agarose pads that allow precise control of animal orientation. These channels enable researchers to rotate and fix C. elegans in specified positions, facilitating the simultaneous imaging of multiple structures and improving image resolution by bringing target cells closer to the microscope objective. This is particularly useful for imaging regenerated neuronal fibers after surgery, which may grow in directions difficult to capture with traditional flat agar pads. This method is accessible, as fabricating channeled agar pads requires the same time and materials as flat pads, making it a practical option for most laboratories.
