WJ-MSCs stored in AD CSF maintain viability. WJ-MSCs stored under hypothermic conditions (one MEMα 1x media group, four AD CSF samples, and three normal CSF samples) were stained with Annexin V/7-AAD and subsequently analyzed by fluorescence-activated cell-sorting (FACS). Images of the cells were taken, and CCK-8 assays were performed. (a) Apoptosis was evaluated after 72 hours. (b) Ratio of non-apoptotic/early apoptotic cells from FACS analysis. (c) Images of seeded cells were taken (scale bar = 40 μm). (d) CCK-8 assay results acquired every 24 hours up to 72 hours. *P < 0.05; ***P < 0.001.
