The effect of glycerol as a cryoprotective agent in the cryopreservation of adipose tissue.

ABSTRACT:

Background

Long-term preservation of adipose tissue is crucial for clinical applications. Researchers should consider both efficiency and biosafety when choosing a cryoprotective agent (CPA) for adipose tissue preservation. Glycerol has been applied as a nontoxic CPA for multiple tissues but not adipose tissue. We aimed to evaluate the efficacy of glycerol as a CPA for adipose tissue cryopreservation.

Methods

Fresh human adipose tissues were obtained from patients who underwent liposuction and divided into 1 mL samples. Each sample was randomly mixed with 1 mL of CPA: 60-100% glycerol, 0.25 mol/L trehalose or DMSO + FBS and cryopreserved in - 196 °C liquid nitrogen for one month. After thawing and elution, the tissues were immediately evaluated for activity and structural in
