Cell viability is not affected by partial gravity. Cell viability was assessed by counting trypan blue treated cells manually, following 24 h of growth on the RPI or inside an incubator under normal culture conditions (1 g). The three different algorithms for partial gravity simulation (see Materials and Methods) were compared in the following order: Two Velocities, Flexible Static Intervals, and Fixed Static Intervals. Means ± standard deviations were obtained from three independent series of experiments.
