Aged NHEKs undergo minimal cell volume changes post‐SSR and have lower TAUT mRNA and protein expression than young NHEKs. Primary NHEKs from (a) young and (b) aged donors were exposed to 80 mJ SSR in the absence and presence of organic osmolytes. Cells were imaged at 1 and 4 hr following exposure, and percentage cell volume changes were calculated for (c) young and (d) aged NHEKs relative to the no SSR control. Data expressed as mean ± SD (one‐way ANOVA), n = 30 cells from three young and n = 30 cells from three aged donors. NHEKs, normal human epidermal keratinocytes; SSR, solar simulated radiation; t, time (in hours)
