Effect of cyclic mechanical stretch in TGF-β1 secretion: Three different human TM primary cultures were subjected to 12 h of cyclic mechanical strain (5% elongation, 1 cycle/sec). A: Concentration of total TGF-β1 released to the culture medium assayed by ELISA. B: Percentage of TGF-β1 increase in the culture medium from stretched cells compared to the non-stretched cultures. Data represent the mean values±SD. Statistical analysis was done using t-test. *Significantly different from control (P<0.05).
