Scientists release large-scale in situ cryo-ET resource for mouse sperm ultrastructure

The scale, quality and regional coverage of public cryo-electron tomography (cryo-ET) data resources have been insufficient, severely limiting data reuse, cross-regional comparisons and the development of automated analysis methods. A new resource aims to help fill that gap, providing 1,413 reconstructed tomograms and associated data from wild-type C57BL/6J mouse sperm.
