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

Figure 4

Decreased TUNEL positive cells in ACQ fed mice. After UVB irradiation (600 mJ/cm²), sections were stained for apoptotic cells. Compared to numerous TUNEL positive cells in control mice, ACQ fed mice rarely showed TUNEL positive cells (dashed line means basement membrane, ×200; scale bar is 50 μM).
