Cell banking and cryopreservation of SVF: what storage can and cannot promise

Cell banking stores a person's own cells frozen for possible future use. This article explains cryopreservation, what studies show about SVF viability after thawing, and the questions to ask before paying for storage.

Quick answer

Cell banking isolates cells such as adipose SVF and stores them in liquid nitrogen at about −196 °C. Freezing and thawing reduce the number of living cells, though surviving cells may keep their potency. Storage does not by itself guarantee that an approved, effective treatment using the cells will be available later.[1][2]

Cryopreservation

Cryopreservation is the cooling and storage of cells, tissues or organs at very low temperatures to save them for future use.[1] Cells are mixed with cryoprotectant, cooled in a controlled way and held in liquid nitrogen.

Evidence on SVF

A 2019 study found that cryopreservation reduced SVF cell counts but not the stem cell potency of surviving cells.[2] A 2026 systematic review examined the effects of cryopreservation on SVF viability across studies.[3] Thaw viability should be measured before any clinical use.

Questions to ask a cell bank

  • Is there an approved future use for the stored cells?
  • How is viability tested after thawing, and what are your results?
  • Is the facility licensed for cell processing and storage?
  • What are the contract terms, fees and what happens if the company closes?[4]

Provider claims

SC301 offers an SVF cell banking service and states that cells are stored at −196 °C and not culture-expanded; other statements on its cell banking page, such as efficiency multiples, are marketing claims without cited studies.[5]
