Chidamide intensified IDA-induced cell cycle arrest in CD34⁺CD38⁻ KG1α cells. (a) CD34⁺CD38⁻ KG1α cells were exposed to 5 or 10 nM IDA with or without 0.5 or 0.75 μM chidamide for 72 h, after which flow cytometric analysis was performed to determine the cell cycle. Horizontal lines represented the mean ± S.D. from three independent experiments. (b) Representative data for flow cytometric analysis of PI staining in CD34⁺CD38⁻ KG1α cells after exposed (72 h) to 5 or 10 nM IDA with or without 0.5 or 0.75 μM chidamide
