Deviation patterns of non-typical viscoelastic creep response of hMSCs. After reaching equilibrium length, 34% of the hMSCs experienced a further increase of length with time (deviation 1) while 14% of the hMSCs reached a peak aspiration length before dropping to a lower equilibrium length (deviation 2). A small amount of hMSCs (7%) exhibited a step-wise deformation behavior (deviation 3). Lines connecting data point indicate data trend.
