# Exosome Preservation **Entity class:** Biological-preservation practice **Domain:** Cell biology / Biobanking **Maturity:** Developed ## Definition Exosome preservation stores extracellular vesicles carrying proteins, lipids, and nucleic acids for research, diagnostic, or possible therapeutic use. ## Mechanism and significance Because exosome composition changes with cell state and handling, provenance and preservation protocols are part of the biological meaning of the sample. ## Relationships - **Research dossier:** [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] - **Ontology route:** [[ASI and RSI Timeline Ontology#Generative Humans, Continuity, and Presence|Generative Humans, Continuity, and Presence]] - **Primary fields:** [[Digital Human Twin]] · [[Machine Succession]] · [[Posthumous Avatar]] - **Adjacent concepts:** [[Natural Killer Cell Preservation]] · [[T-Cell Preservation]] · [[Biological Cloning from Preserved Cells]] ## Sources and provenance - [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] — immediate source for this node's role in the broadcast research map. ## Evidence boundary The research dossier establishes why this entity or concept belongs in the Moonshots ontology. Time-sensitive organizational, product, policy, and performance claims should be checked against the linked primary source or a current authoritative source before reuse as settled fact.
