To evaluate the effect of dermal fibroblast (DF)‐derived exosomes on the expression of biomarkers associated with skin barrier functions, FLG, IVL, LOR, and HAS1 expression in human skin keratinocytes (HaCaT) cells was assessed through immunoblotting. (A) Protein expression analysis of human keratinocytes (HaCaT cells) treated with fibroblast‐derived exosomes. (B) Protein expression associated with fibroblast‐derived exosome treatment of 1‐chloro‐2,4‐dinitrobenzene (DNCB)‐treated human keratinocytes.
