Figure Lengend Snippet: Effect of UVB irradiation on the proliferation and survival of ASCs. (A) Proliferation was measured 72 h after UVB irradiation using MTT assay. A low-dose UVB exposure did not affect, while a high dose reduced the ASC proliferation. (B) H2O2 treatment (0.5 mM for 24 h) induced the cell death, but low-dose UVB preconditioning increased ASC survival. (C) H2O2 treatment enhanced the PI staining of ASC nuclei, which was attenuated by UVB irradiation. (D) Western blot analysis showed that the phosphorylation of survival-related signaling molecules was significantly increased by UVB treatment. **P<0.01.

Figure Lengend Snippet: Induced telogen-to-anagen transition by UVB preconditioning. After UVB irradiation, cells (A, B) or CM (C, D) were injected on the back of C3H/HeN mice. (A) Compared with untreated control ASCs, UVB treatment (ASCUVB) significantly accelerated the telogen-to-anagen transition at 14 days. (B) In addition, hair weight was significantly increased in the ASCUVB group at 18 days (n=5 for each group). (C) Compared with ASC-CM, subcutaneous injection of UVB-CM significantly induced the telogen-to-anagen transition at 14 days. (D) Hair weight was significantly increased in the UVB-CM injection group at 14 days (n=5 for each group). **P<0.01.
