Fig. 5From: Anti-aging effect of β-carotene through regulating the KAT7-P15 signaling axis, inflammation and oxidative stress processEffect of β-carotene on replicative senescence of Ad-MSCs. A Relative cell proliferation detection upon β-carotene treatment by using the IncuCyte S3 live-cell imaging system. n = 5 biological replicates. B The percentage of Ki67-positive cells was increased by β-carotene treatment. At least 50 cells were statistically analyzed. C, D Effect of β-carotene on the properties of MSCsBack to article page
