Cell Lineage and Identity Should Be Treated as Controlled Data
Holding
Cell-based research requires a traceable identity chain from source material through passage, modification, assay, and disposition.
Issue
Cell identity can be compromised by labeling errors, cross-contamination, undocumented passage history, or unclear links between a parent culture and its derivatives. These are data failures with experimental consequences.
Analysis
The practical issue is loss of lineage context. A result may be technically measured but impossible to interpret because the exact material, passage state, or modification history is uncertain.
Resolution
The system should assign controlled identities, record parent-child relationships, capture passage and handling events, and connect assay outputs to the exact material used. Suspect identity should trigger quarantine and review.
Evidence Package
The evidence should show source records, authentication results, passage history, storage events, modification records, assay links, quarantine actions, and release decisions.
Conclusion
Cell-based results should not be considered interpretable until the identity and lineage of the tested material are documented.
