Human paraffin tissue arrays, commonly referred to as human formalin-fixed paraffin-embedded (FFPE) tissue microarrays (TMAs), are high-throughput research tools that enable the simultaneous analysis of multiple human tissue specimens under standardized experimental conditions. A tissue microarray consists of small cylindrical cores precisely transferred from donor FFPE tissue blocks into a single recipient paraffin block while preserving tissue architecture and histopathological characteristics. This standardized format minimizes technical variability, reduces tissue and reagent consumption, and supports high-throughput comparative analyses across normal tissues, benign lesions, and a wide range of human diseases. Because all specimens are analyzed on the same slide under identical experimental conditions, TMAs improve analytical reproducibility and facilitate direct comparison of molecular and histopathological features. Human FFPE tissue microarrays are extensively used in pathology, oncology, immunology, neuroscience, and translational biomedical research for biomarker discovery, validation, and molecular characterization.
