Table 1.

Degree of anisotropy (D.A.) measured for different cell populations based on the surface displacement profiles.

		D.A.
NIH-3T3	w/o actin stain	1.6 ± 0.4 (n = 18)
	SiR-actin	1.8 ± 0.6 (n = 25)	cap: 2.1 ± 0.5 (n = 15) sparse cap: 1.4 ± 0.2 (n = 4) no cap: 1.2 ± 0.2 (n = 6)
	Actin-GFP	1.7 ± 0.5 (n = 25)	cap: 2.1 ± 0.5 (n = 13) sparse cap: 1.5 ± 0.2 (n = 9) no cap: 1.1 ± 0.1 (n = 3)
	After LatA treatment	1.1 ± 0.1 (n = 15)
MDA-MB-231	w/o actin stain	1.2 ± 0.2 (n = 13)
	SiR-actin	1.1 ± 0.1 (n = 12)
	Actin-GFP	1.1 ± 0.1 (n = 15)

In the case when cells were stained for actin, the D.A. for subgroups (cap, sparse cap, no cap) is also presented. Mean ± s.d.
