title = "Micromechanical elastomeric devices for investigations of mechanobiology in human embryonic stem cells",
abstract = "Human embryonic stem cells (hESCs) provided a cell source for biotechnological and clinical applications. Yet, there is limited understanding of how mechanical signals in the microenvironment of hESCs regulate their fate decisions. Here, we applied a microfabricated micromechanical platform to investigate mechanoresponsive behaviors of hESCs. We demonstrated that hESCs are mechanosensitive, and they could increase their cytoskeleton contractility with matrix rigidity. Furthermore, rigid substrates supported maintenance of pluripotency of hESCs. Matrix mechanics-mediated cytoskeleton contractility of hESCs might be functionally correlated with E-cadherin expressions in cell-cell contacts and thus involved in fate decisions of hESCs. Our results provided a novel approach to characterize and understand mechanotransduction in hESC function regulation.",
