Cell viability and apoptosis of the preserved ECSs. The optical density value showed that the ECS viabilities of the low-temperature storage groups were significantly lower than those of the control group, especially in the refrigerated-1 group. The ECS viabilities of the cryopreserved groups decreased slightly. The cell survival rate of each group calculated by trypan blue staining was consistent with CCK-8. In the apoptosis detection assay, compared with the control group, all preserving groups had an increased rate of apoptosis, and the ECSs in the frozen-2 group performed the best in reducing apoptosis. Scar bar: 50 μm
