Overview
ISO/TS 22859:2022 - "Biotechnology - Biobanking - Requirements for human mesenchymal stromal cells derived from umbilical cord tissue" - provides technical specifications for the biobanking lifecycle of human umbilical cord‑derived mesenchymal stromal cells (hUC‑MSCs, from Wharton’s jelly). The document defines requirements for collection, isolation, expansion, characterization, quality control, cryopreservation, storage, thawing, disposal, distribution and transport specifically for research and development (R&D) and preclinical use. It does not apply to hUC‑MSCs intended for in vivo clinical or therapeutic applications.
Key topics and technical requirements
ISO/TS 22859:2022 addresses the full chain of custody and technical practices for hUC‑MSC biobanking. Core topics include:
- Donor and sample collection: requirements for collection of umbilical cord tissue and associated donor data to ensure traceability and informed handling.
- Transport and reception: procedures for transport of tissue or cell materials to the biobank and reception traceability.
- Isolation and expansion: standardized approaches for isolation, primary culture and limited expansion of hUC‑MSCs, including unique identification and testing for infectious agents.
- Characterization assays: mandatory and recommended analyses such as viability, morphology, population doubling time (PDT), purity, in vitro self‑renewal and multilineage differentiation (adipogenic, chondrogenic, osteogenic), immunophenotyping (flow cytometry), secretome/protein assays and immunoregulation testing.
- Quality control (QC): QC test procedures to monitor identity, sterility, potency‑related attributes and contamination.
- Cryopreservation & storage: requirements for freezing, controlled-rate processing, storage conditions and inventory management.
- Thawing, disposal, distribution & transport: validated thawing procedures, safe disposal of materials and packaging/transport rules for frozen or living cultures.
- Documentation & data management: information systems, record keeping and traceability consistent with biobanking best practice.
Informative annexes provide exemplary QC procedures, isolation methods and characterization methods to support implementation.
Applications and who should use it
ISO/TS 22859:2022 is intended for:
- Academic research centres and university biobanks
- Public and private R&D facilities managing hUC‑MSC collections
- Preclinical research groups requiring standardized cell materials
- Biobank managers implementing or improving hUC‑MSC workflows
Use of this technical specification helps improve reproducibility, sample comparability across institutions, and quality assurance for hUC‑MSC materials used in research.
