  1. Analysis of the differences among group means using Paired Two Sample t-Test for Means (alpha 0,05). Values are shown as a mean ± standard deviation (SD). P-value for the analysis of the differences between the sample means of control and ethanol (C/E), control and H2O2 (C/H), control and cryopreserved groups (C/Cryo).
