Effects of keratinocyte stem/progenitor cells conditioned medium (KSC-CM) on the proliferation of hair follicle dermal papilla cells (HFDPCs). (A) Cell proliferation was measured 48 h after concentrated KSC-CM treatment; (B) Western blot analysis against phospho-AKT and phospho-ERK1/2 showed that these pathways are activated by KSC-CM; (C,D) Cell cycle analysis of HFDPCs was performed by flow cytometry, and we found that the fraction of S phase cells was increased following 24 h (C) and 48 h (D) of concentrated KSC-CM treatment. ** p < 0.01.
