Expression of integrin subunits in IOSE 29 cells growing as a monolayer and as spheroids for 2 days

Integrin subunit	Monolayer (MIF)	Spheroid day 2 (MIF)
α2	830 ± 91	542 ± 142
α3	889 ± 69	335 ± 34*
αv	105 ± 84	95 ± 14
α6	1332 ± 171	176 ± 64*
β1	701 ± 84	294 ± 54*

Values are expressed as mean intensity of fluorescence (MIF)

± SEM of three different readings obtained from independent experiments.

*Significantly different from cells growing as a monolayer (p < 0.05).
