Abstract

Abstract : Stem cell‐based tissue engineering provides a prospective strategy to bone tissue repair. Bone tissue repair begins at the recruitment and directional movement of stem cells, and ultimately achieved on the directional differentiation of stem cells. The migration and differentiation of stem cells are regulated by nucleoskeletal stiffness. Mechanical properties of lamin A/C contribute to the nucleoskeletal stiffness and consequently to the regulation of cell migration and differentiation. Nuclear lamin A/C determines cell migration through the regulation of nucleoskeletal stiffness and rigidity and involve in nuclear‐cytoskeletal coupling. Moreover, lamin A/C is the essential core module regulating stem cell differentiation. The cells with higher migration ability tend to have enhanced differentiation potential, while the optimum amount of lamin A/C in migration and differentiation of MSCs is in conflict. This contrary phenomenon may be the result of mechanical microenvironment modulation. Abstract : The migration and differentiation of stem cells are regulated by nucleoskeletal stiffness. Mechanical properties of lamin A/C contribute to the nucleoskeletal stiffness and consequently to the regulation of cell migration and differentiation.
