FRTL-5 Metabolic Activity, ROS production, and Cell Number in Response to Treatment. (A). Oscillation significantly increased FRTL-5 cell metabolic activity compared to no oscillation both with and without TSH (* p=0.0244, ** p=0.0014, *** p=0.0002, **** p<0.0001). (B) Oscillation significantly increased ROS compared to no oscillation both with (** p=0.0026) and without (** p=0.0077) TSH (p****< 0.0001). (C) Cell number was not significantly affected by TSH or oscillation.
