Fig. 2From: Periodic mild heat stimuli diminish extracellular matrix synthesis in pellet cultured human chondrocytesImmediate and accumulative effects of heat stimulus on mRNA expression. a Relative mRNA expression of HSPA1A, ACAN, COL2A1, and COL1A1 at 0, 1, 6, 24 h after heat stimulation. b Relative mRNA expression of COL2A1, COL1A1, and ACAN on day 7 is shown. Values represent the means and standard deviations. Asterisk indicates P < 0.05Back to article page
