Comparison of cell recovery and repopulation capability. Cell viability was analyzed immediately after thawing, using the trypan blue exclusion method (n = 12). The mean value with standard error of the mean (SEM) of each group is presented (a). Cell repopulation capability after cryopreservation was evaluated 48 h after thawing, using the MTT assay (n = 12). The absorbance (A570–A630) values were normalized to unfrozen (Live) sample values. The percentage ratio with SEM of each group is presented (b)
