"Mastering Tissue Microarray: From Project Design to AI-Powered Analysis"

Mastering Tissue Microarray: From Project Design to AI-Powered Analysis offers an in-depth exploration of the tissue microarray (TMA) methodology, guiding readers through each stage of the process—from initial project design and tissue selection to array construction, staining, and high-resolution imaging. The book emphasizes best practices, quality control measures, and standardized protocols to ensure robust and reproducible results. A key feature of the text is its focus on the integration of artificial intelligence and machine learning techniques for advanced image analysis and biomarker quantification. This comprehensive resource bridges traditional histopathology with modern computational tools, enabling high-throughput analysis and accelerating translational research. Designed for biomedical researchers, pathologists, and data scientists, this volume serves as both a practical manual and a conceptual guide for leveraging TMA technology in diagnostics, biomarker discovery, and personalized medicine.
