Figure 8. Expression tendency of Piezo on matrix with different stiffness. (A) The expression of Piezo1 on different matrix with stiffness in grade. (B) The expression of Piezo2 in the same condition. QPCR results showed that Piezo1 increased in stiffness-dependent mode, and Piezo2 showed no obvious trend with stiffness. *P<0.05, **P<0.01,***P<0.001. n=3.
