Perfusion fluid and thawing after cryopreservation increase ROS production and reduce metabolic activity in MSC. (A) ROS production in fresh and frozen-thawed pMSC suspended in culture medium or in perfusion fluid. (B) ROS production in fresh and in frozen-thawed hMSC suspended in culture medium or in perfusion fluid. (C) Metabolic activity measured by XTT reduction by NADH of fresh and frozen-thawed pMSC after 30 min and 2 h incubation in perfusion fluid. (D) Metabolic activity measured by XTT reduction by NADH of fresh and frozen-thawed hMSC after 30 min and 2 h incubation in perfusion fluid (n = 5). Results are shown as means ± SD. *p < 0.05; **p < 0.01.
