Tools for efficient analysis of neurons in a 3D reference atlas of whole mouse spinal cord
Ontology highlight
ABSTRACT: SUMMARY To fill the prevailing gap in methodology for whole spinal cord (SC) analysis, we have (1) designed scaffolds (SpineRacks) that facilitate efficient and ordered cryo-sectioning of the entire SC in a single block, (2) constructed a 3D reference atlas of adult mouse SC, and (3) developed software (SpinalJ) to register images of sections and for standardized analysis of cells and projections in atlas space. We have verified mapping accuracies for known neurons and demonstrated the usefulness of this platform to reveal unknown neuronal distributions. Together, these tools provide high-throughput analyses of whole mouse SC and enable direct comparison of 3D spatial information between animals and studies. Graphical abstract In brief Fiederling et al. provide tools for efficient analysis of neurons and their processes within the entire mouse spinal cord. A 3D reference atlas puts images into anatomical context and allows integration of data from different studies. They demonstrate the usefulness of this methodology, analyzing known and previously unknown neuronal distributions.
