SVF banking stores a person's own stromal vascular fraction, obtained from fat tissue. Cord blood banking stores blood collected from the umbilical cord at birth. For either service, storage does not guarantee that an approved, effective treatment will be available. Compare approved uses, viability after thawing, licensing and contract terms before signing.","detailed_answer":"<p>Both services rely on cryopreservation, which means cooling and storing cells at very low temperatures for future use<span class=\"ref\">[1]</span>. The comparison below is limited to what this entry's sources support.
