Objective: To investigate the chemosensitivity of ovarian cancer SK-OV-3ip1 multicellular aggregates (MCA) to cisplatin and taxol and to explore the possible mechanisms. Methods: Liquid overlay system was employed to obtain MCA. We detected the resistance using trypan blue exclusion testing, clonogenic assay, cell cycle profiles and apoptosis with flow cytometry (FCM). Results: After cisplatin exposure, MCA cells showed nearly equal cell viability with monolayer cells (P=0.05). After 40(M cisplatin exposure for 12 h, no clone ((50 cells) was formed, but more viable cells attached to the bottom of 24-well plate in MCA group than monolayer. Furthermore, apoptosis rate and cell cycle profiles with FCM had no significant change between MCA and monolayer cells. After taxol exposure, however, trypan blue exclusion testing demonstrated higher cell viability in MCA cells (P=0.003) and higher clone formation rate in 100-cell group than monolayer cells (0.01
