Acta Histochemica et Cytochemica is the official online journal of the Japanese Society of Histochemistry and Cytochemistry, aimed at the rapid publication of original research articles in the fields of histochemistry and cytochemistry. We welcome manuscripts that address significant methodological advancements in these areas, and researchers from any country may submit manuscripts in English, regardless of their membership status with the Japanese Society of Histochemistry and Cytochemistry. All submitted manuscripts must be original works that have not been published elsewhere, excluding abstracts. Manuscripts that are substantially similar to papers that have been published, accepted, or are under consideration will not be considered. All submitted papers will undergo peer review by at least two reviewers selected by the appropriate associate editor, based on criteria including scientific significance, originality, and clarity. If revisions are necessary, authors must submit the revised manuscript within three months; otherwise, it will be treated as a new submission. The editor-in-chief will make all final decisions regarding acceptance.
