Different cell culture densities alter cellular GSH dynamics and oxidant resistance. A F510/F580 ratio according to cell density (n = 5 per group). B GSH level changes according to hES-MSCs culture density after diamide treatment (n = 5 per group). C mRNA expression of stem cell markers in hES-MSCs cultured at different cell densities measured by real-time PCR (n = 5 per group). D (above) Transwell migration assay in hES-MSCs cultured at different cell densities (n = 5 per group). (below) Colony-forming assay in hES-MSCs cultured at different cell densities (n = 5 per group). **p < 0.01, ****p < 0.0001
