Figure 6: Dynamic morphological response of hMSCs to mechanical stresses over time.

(a–d) Change in aspect ratio (AR) of hMSCs vs. time for four types of hMSCs (Type A–Type D). Each histogram was extracted from n > 30 cells. Phase contrast images of representative cells for the four types (Type A–D) at t = 20 d are presented as insets. The cell contour was highlighted in yellow.
