    Area of Science:

    • Hematology
    • Histotechnology

    Background:

    • Accurate identification of bone marrow cells is crucial for hematological studies.
    • Existing methods for marrow section preparation may require optimization for quantitative analysis.

    Purpose of the Study:

    • To develop and systematically evaluate improved methods for preparing human bone marrow sections.
    • To facilitate accurate identification and quantitative assessment of bone marrow cellularity.

    Main Methods:

    • Two distinct methods involving methyl methacrylate embedding of marrow cores were developed.
    • Method 1: Acrolein fixation, deplasticization, and staining with eosin-Y and azure II.
    • Method 2: Neutral-buffered formalin fixation with esterase-specific staining for neutrophilic forms.

    Main Results:

    • Both developed methods enable the preparation of high-quality human bone marrow sections.
    • The preparations are suitable for detailed cellular identification and quantitative studies.
    • Specific staining protocols allow for clear visualization of different cell types.

    Conclusions:

    • The presented methods offer reliable techniques for human bone marrow section preparation.
    • These advancements support more accurate diagnostic and research applications in hematology.
    • The methods are validated for their utility in quantitative cellularity studies.
