Differential Influence of Components Resulting from Atmospheric-Pressure Plasma on Integrin Expression of Human HaCaT Keratinocytes

Figure 2

Expression of 𝛼₂-integrin/CD49b (a) and 𝛽₁-integrin/CD29 (b) on HaCaT cells which were recovered by trypsin 24 h after treatment with surface DBD/air (red line; 𝑁=8) or DBD/argon (blue line; 𝑁=7) plasma. Cells were treated for 20 s to 300 s. Untreated cells served as controls (see time 0). Expression of surface molecules was determined by flow cytometry using monoclonal antibodies. Mean fluorescence intensity (MFI) in log 𝑈 of positive stained cells is presented (mean ± SEM). ^∗𝑃<0.05, ^∗∗𝑃<0.01, ^∗∗∗𝑃<0.001 (𝑡-test); ^##𝑃<0.01 (Mann-Whitney test) versus control cells; ^⋆𝑃<0.05, ^⋆⋆𝑃<0.01 (𝑡-test).
