tissuesuch

Tissuesuch is a term used to describe the set of processes, tools, and standards involved in locating and retrieving tissue samples and tissue-related data across biological repositories, clinical archives, and digital platforms. The word combines tissue with the German word Suche, meaning search, underscoring its focus on discovery and retrieval in both laboratory and informatics contexts. In practice, tissuesuch encompasses physical inventory management as well as computational search across heterogeneous data sources.

Its scope includes tracking of physical specimens through barcodes and RFID tagging, organizing tissue microarrays, and identifying corresponding slide images, reports, and associated metadata. On the digital side, tissuesuch relies on standardized metadata, ontologies, and indexing to enable fast and precise discovery. Methods may include ontology-based search using anatomical terms (for example, UBERON) and disease vocabularies, natural language processing of pathology notes, image-based region localization in digitized slides, and provenance tracking to document sample history.

Applications of tissuesuch appear in biobanking, retrospective research using tissue cohorts, and digital pathology workflows that require rapid retrieval of relevant specimens and data. It supports cross-institutional collaboration by enabling standardized search across repositories while maintaining data governance and access controls.

Challenges include achieving semantic interoperability across institutions, maintaining data quality and completeness of metadata, safeguarding patient privacy, and keeping up with evolving ontologies and standards. Because tissuesuch is not yet a single standardized term in the literature, its practical definition can vary between organizations.
