Psoriatic Dermal-derived Mesenchymal Stem Cells Reduce Keratinocyte Junctions, and Increase Glycolysis.

ABSTRACT: Although it is known that psoriatic dermal-derived mesenchymal stem cells (DMSCs) dysregulate keratinocyte proliferation, the biological activity profile of keratinocytes influenced by psoriatic DMSCs remain unknown. In the present study, we assessed the impact of psoriatic DMSCs on keratinocyte proliferation, differentiation, and glucose metabolism in normal human epidermal keratinocytes co-cultured with or without psoriatic DMSCs. Co-culture of normal human epidermal keratinocytes with psoriatic DMSCs downregulated expression levels of proteins associated with cell junction assembly (alpha-actinin-1, catenin beta-1, poliovirus receptor-related protein 4 and procollagen-lysine, 2-oxoglutarate 5-dioxygenase 2), while upregulating proteins associated with keratinocyte proliferation and diff
