FGF2 and psoriasis: In one of earlier studies, we found that dermal mesenchymal stem cells (DMSCs) derived from patients with psoriasis had an imbalance in cytokine secretion, including the increased levels of epidermal growth factor (EGF), stem cell factor (SCF), and interleukin-1 (IL-1) as well as the decreased levels of basic fibroblast growth factor (bFGF), IL-3, IL-6, IL-8, and hepatocyte growth factor (HGF) [8].
