Ovarian cancer cell line HO-8910 cells were investigated in
this study. They were presented by Junyan Xiang from the Institute
of Ultrasound and Medicine Engineering, Chongqing Medical
University, Chongqing. The cells were grown in Dulbecco’s modified
Eagle Medium (DMEM) supplemented with 10% fetal bovine
serum (FBS) and antibiotics (50 mg/mL penicillin and 50 mg/mL
