Toluidine blue staining of murine mast cells and quantitation by a novel, automated image analysis method using whole slide skin images.
Mast cells are immune cells of myeloid lineage, characterized by the presence of cytoplasmic granules. These cells play a significant role in multiple pathologies, such as urticaria and type 1 hypersensitivity reactions. Mast cells in tissue sections can be demonstrated with metachromatic stains, such as toluidine blue. Metachromatic staining of mast cells is influenced by the type of mast cell, pH of the staining solution and fixative employed. The objective of this study is to identify a simple, consistent, and reproducible toluidine blue staining method to quantify the mast cells in whole slide skin images using automated image analysis. Skin sections from naive mice and atopic dermatitis mice were stained with toluidine blue methods by Churukian-Schenk and Luna. Luna's toluidine blue staining method without the eosin counterstaining provided optimal staining of mast cells with a greater contrast to the background. The Churukian-Schenk toluidine blue method resulted in slight background staining which confounded the accurate detection and quantification of mast cells in mouse skin sections using an automated image analysis algorithm. Using the Luna toluidine blue stain, a 5-fold increase in the total number of mast cells was observed in atopic dermatitis skin samples as compared to naive mice. In summary, a simple, conventional, and reproducible toluidine blue method was identified to quantify the mast cells in mouse skin sections using an automated image analysis algorithm.
期刊介绍:
The official journal of the National Society for Histotechnology, Journal of Histotechnology, aims to advance the understanding of complex biological systems and improve patient care by applying histotechniques to diagnose, prevent and treat diseases.
Journal of Histotechnology is concerned with educating practitioners and researchers from diverse disciplines about the methods used to prepare tissues and cell types, from all species, for microscopic examination. This is especially relevant to Histotechnicians.
Journal of Histotechnology welcomes research addressing new, improved, or traditional techniques for tissue and cell preparation. This includes review articles, original articles, technical notes, case studies, advances in technology, and letters to editors.
Topics may include, but are not limited to, discussion of clinical, veterinary, and research histopathology.
