Recent advancements in staining techniques are profoundly reshaping the fields of cytology and histology, leading to enhanced diagnostic accuracy and a deeper understanding of subtle cellular features. Innovations such as multiplex immunohistochemistry (IHC) allow for the simultaneous detection of multiple biomarkers, significantly improving workflow efficiency and providing a more comprehensive view of tissue architecture [1].
Multiplex immunohistochemistry (mIHC) is emerging as a transformative approach in cancer diagnostics, enabling the visualization of numerous protein targets within a single tissue section. This facilitates a more nuanced understanding of tumor heterogeneity and the tumor microenvironment than traditional singleplex IHC methods [2].
The development of novel fluorescent probes and labeling strategies has markedly improved the sensitivity and specificity of immunofluorescence (IF) techniques in histology. These advancements enable the detection of low-abundance targets and the multiplexing of a greater number of antibodies, offering deeper insights into cellular processes and disease mechanisms [3].
Digital pathology, driven by advanced imaging and artificial intelligence (AI), is revolutionizing histological analysis. High-resolution whole-slide imaging combined with deep learning algorithms facilitates automated detection and quantification of various cellular features, including mitotic figures, nuclear atypia, and tumor infiltration [4].
Standardization of staining protocols remains a critical factor in ensuring the reproducibility and comparability of results in both cytology and histology. Recent efforts are directed toward developing more robust and automated staining platforms that minimize manual variations and optimize reagent concentrations, incubation times, and washing steps [5].
The application of advanced staining techniques in liquid-based cytology (LBC) has substantially improved the detection of various cytological abnormalities, including precancerous lesions. Refined Papanicolaou (Pap) staining for LBC, coupled with the integration of immunocytochemistry (ICC), enhances diagnostic confidence and reduces the need for repeat sampling [6].
Novel chromogenic substrates and counterstains are being developed to provide sharper contrast and more stable staining in immunohistochemistry (IHC). These innovations address limitations of traditional reagents, such as background staining and fading, leading to clearer visualization of cellular morphology and precise antigen localization [7].
The integration of spatial transcriptomics and multiplexed imaging techniques enables the simultaneous analysis of gene expression and protein localization within their native tissue context. This offers an unprecedented understanding of cellular heterogeneity and intercellular communication in diverse biological states [8].
The development of AI-powered image analysis platforms for histology is accelerating the interpretation of complex stained slides. These platforms can accurately identify and quantify morphological features, detect subtle anomalies, and even predict treatment responses based on visual patterns [9].
In situ hybridization (ISH) techniques continue to evolve, offering precise localization of nucleic acids within cells and tissues. Recent advancements have focused on improving sensitivity and enabling multiplexing of RNA and DNA probes, often in conjunction with IHC for protein detection, leading to more comprehensive molecular profiling of tissues [10].
