Fig. 5. Cytotoxicity of fungal melanin derived from A. resinae in HaCaT human keratinocytes with an exposure time of (A) 24 h (B) 48 h (C) 72 h, and (D) 96 h. Data shown are mean ± standard deviation of five independent experiments. * indicates statistically significant differences (p < 0.05) in comparison with the group incubated with 0 mg mL−1 of melanin.
