Kinetics of chondrocyte marker expression after mechanical stimulation with a square pressure signal. Micropellets of 21 days were stimulated by a square-wave pressure with an amplitude of 3.5 kPa and a frequency of 1 Hz for 30 min. Expression of SOX9, AGG and COL IIB was evaluated 0, 3, 6, 15 and 24 h after mechanical stimulations and compared to non-stimulated control (NS) (n = 7–9 groups of 6 micropellets). Statistical analysis used Wilcoxson signed rank test, and results are expressed as *: p < 0.05
