Figure 5

Antimicrobial diffusion assays with the supernatants of APEs-exposed keratinocytes. Tet, tetracycline, was included as a positive control (2.25 μM, 1 mg/mL). The negative control was supernatants of cells without elicitor (37°C, 24 h). Error bars represent SEM and significant values of Student’s tests are depicted as ; ; .
