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

Figure 5

Decreased DCF staining and increased p63 positive cells in ACQ fed mice. (a) After UVB irradiation, control mice showed strong DCF staining but ACQ fed mice showed weak DCF staining (dashed line means basement membrane; scale bar is 50 μM). (b) Confocal microscopic examination showed that there is strong signal of p63 and integrin α6 in ACQ fed mice compared to control mice. There was nonspecific staining of integrin α6 at the upper dermis (green; p63 staining, red; integrin α6 staining, ×200, scale bar is 50 μM).
