Mechanical stimulation of cyclic tensile strain induces reduction of pluripotent related gene expressions via activation of Rho/ROCK and subsequent decreasing of AKT phosphorylation in human induced pluripotent stem cells

► Mechanical stimulation is an important factor for regulation of stem cell fate. ► Cyclic stretch to human induced pluripotent stem cells activated small GTPase Rho. ► Rho-kinase activation attenuated pluripotency via inhibition of AKT activation. ► This reaction could be reproduced only by transfection of dominant active Rho. ► Rho/ROCK are important molecules in mechanotransduction and control of stemness.
