Chromosomes undergo dramatic compaction during mitosis, but accurately measuring their volume has been challenging. Employing serial block face scanning electron microscopy, Cisneros-Soberanis et al. (https://doi.org/10.1083/jcb.202403165) report that mitotic chromosomes compact to a nucleosome concentration of ∼760 µM.
期刊介绍：
The Journal of Cell Biology (JCB) is a comprehensive journal dedicated to publishing original discoveries across all realms of cell biology. We invite papers presenting novel cellular or molecular advancements in various domains of basic cell biology, along with applied cell biology research in diverse systems such as immunology, neurobiology, metabolism, virology, developmental biology, and plant biology. We enthusiastically welcome submissions showcasing significant findings of interest to cell biologists, irrespective of the experimental approach.
