| Actinnarrow (also termed n-actin in Figure 2) corresponds to values obtained from actin movies measured as done for p16 expressers. The average width of measured areas in p16 expressors was approximately 1 μm, whereas the tip measurements were done on regions with a dimension of approximately 0.5 μm. The average width analysed in lamellipodia of actin expressers was 2.8 μm. | ||
