Fig. 1From: Heat-mediated reduction of apoptosis in UVB-damaged keratinocytes in vitro and in human skin ex vivoEffects of UVB and/or heat stress on DNA damage and apoptosis in keratinocytes in vitro and in an ex vivo skin model. Bar graphs of mean ± SD percent keratinocytes that (a and d) harboured DNA damage (CPD), (b and e) were apoptotic, or (c and f) harboured DNA damage and expressed p53 in (a–c) NHEK or (d–f) skin per field of view. Statistically significant differences are indicated with *, ** or *** for p-values <0.05, <0.01 or ≤0.001 respectivelyBack to article page
