Traceability in stem cell research: from participant sample to induced pluripotent stem cell and back

Area of Science:

• Biomedical Research
• Stem Cell Biology
• Drug Discovery and Toxicology

Background:

• Ensuring data integrity and ethical compliance is crucial in multi-site biological research.
• Stem cells are vital for developing novel drugs and predictive toxicology models.
• Current traceability methods may not adequately protect donor privacy across geographical and scientific processes.

Purpose of the Study:

• To describe a novel traceability system for biological materials within the Stem cells for Biological Assays of Novel drugs and prediCtive toxiCology consortium.
• To ensure ethical and legal compliance by protecting donor privacy while maintaining full sample traceability.
• To present a system adaptable for various projects and primary sample types.

Main Methods:

• Development of a combined record and labeling system for biological material.
• Implementation of a unique identification number (UIN) linking each sample aliquot to its original donor.
• Restricting donor identification linkage to authorized personnel at the clinical recruitment site.

Main Results:

• The system successfully links biological samples across geographical locations and scientific processes, from donation to induced pluripotent stem cell lines.
• Full traceability of biological material is achieved while safeguarding donor privacy.
• The system adheres to ethical and legal requirements for data protection.

Conclusions:

• The developed traceability system effectively balances the need for comprehensive sample tracking with stringent privacy protection.
• This innovative system enhances the reliability of stem cell-based drug discovery and toxicology studies.
• The system's adaptability makes it a valuable tool for future biomedical research initiatives.
