Figure 1: Puerarin protected the hOBs from serum-free-induced apoptosis. Cells were treated with 0–10−6 M puerarin, and cells exposed to 10 μM E2 served as the positive control. Apoptosis were measured by ELISA according to the kit specification. The bars represent the mean SD ( ), , as compared with the control cells.
