Exogenous mechanical forces are transmitted through the cell and to the nucleus,
initiating mechanotransductive signaling cascades with profound effects on
cellular function and stem cell fate. A growing body of evidence has shown that
the force sensing and force-responsive elements of the nucleus adapt to these
mechanotransductive events, tuning their response to future mechanical input. The
mechanisms underlying this "mechano-adaptation" are only just beginning to be
elucidated, and it remains poorly understood how these components act and adapt
in tandem to drive stem cell differentiation. Here, we review the evidence on how
the stem cell nucleus responds and adapts to physical forces, and provide a
perspective on how this mechano-adaptation may function to drive and enforce stem
cell differentiation.
