Three-dimensional chromatin structures undergo dynamic reorganization during mammalian spermatogenesis; however, their impacts on gene regulation remain unclear. Here, we focused on understanding the structure-function regulation of meiotic chromosomes by Hi-C and other omics techniques in mouse spermatogenesis across five stages.

The granulocyte immunofluorescence test based on flow cytometry is still the most commonly used method for detecting antineutrophil antibodies. We questioned whether neutrophil prefixation is necessary for this test. Three pretreatment methods using paraformaldehyde were compared: unfixed, short-fixed (3 minutes
