Figure 9. The ((A) a–d) showed the results observed under the inverted microscope after being treated by different concentrations of formononetin for 48 h. Meanwhile, ((B) a′–d′) showed the results treated with DAPI for 48 h to assess cell apoptosis. (a, a′) The MG63 cells were treated with 0μg/mL Form for 48 h (the control group). (b, b′) The MG63 cells were treated with 5 μg/mL Form for 48 h. (c, c′) The MG63 cells were treated with 8 μg/mL Form for 48 h. (d, d′) The MG63 cells were treated with 10 μg/mL Form for 48 h.
