Novel Antioxidant Tripeptide “ACQ” Can Prevent UV-Induced Cell Death and Preserve the Number of Epidermal Stem Cells

Figure 3

Protective effects by ACQ against UV irradiation. Control mice and ACQ fed mice (2 and 4 weeks) were irradiated with 600 mJ/cm² of UVB. In control mice, epidermis became thinner and apoptotic cells were observed. But in ACQ fed mice, epidermis became thicker and severe damage was not observed. Experiment was repeated 2 times and representative data is shown (×200, scale bar is 50 μM).
