ATPR induces differentiation in human NB4 and THP-1 cells. a NB4 cells were treated with ATPR (10⁻⁶ M) for different durations (0–72 h). CD11b and CD14 expression was analyzed by flow cytometry. b THP-1 cells were treated with ATPR (10⁻⁶ M) for different durations (0–72 h). CD11b and CD1 expression was analyzed by flow cytometry. c NB4 and THP-1 cells were treated with ATPR (10⁻⁶ M) for different durations (0–72 h). Then, the protein expression of CD11b was assessed by western blot. d NB4 and THP-1 cells were treated with ATPR (10⁻⁶ M) for 72 h, and the NBT reduction assay detected cell differentiation. *p < 0.05, **p < 0.01 versus control group
