Effects of AP on cell morphology and expansion of UCB- CD34⁺ cells. (A) Chemical structure of AP, (B) Purity of isolated CD34⁺ cells, (C) Cell morphology before and after culturing with AP at two different concentrations (2.5 and 5 µM), photos were captured on day 7 (10× objective, scale bar; 100 μm). The control was composed of cytokines and methanol, (D) Viability of UCB-CD34⁺ cells after treatment with AP at different concentrations for 3, 5, and 7 days. Data are shown as mean ± SEM, *p < 0.05, **p < 0.01 compared to control.
