Figure 3: Expression of a panel of α- and β-integrins on HaCaT cells 24 h after treatment with surface DBD/air plasma (mean ± SEM, ) for 60 s and 300 s. Expression of integrins determined by flow cytometry using monoclonal antibodies was measured as mean fluorescence intensity (MFI) of positive stained cells. The results of plasma treated cells are expressed as percentage of that of untreated control cells. , (t-test); (Mann-Whitney test) versus control cells.
