Dermal fibroblast of the skin. Dermal fibroblasts are derived from mesenchymal stem cells within the body. Like corneal fibroblasts, dermal fibroblast proliferation can be stimulated by the presence of fibroblast growth factor (FGF). Fibroblasts do not appear to be fully differentiated or specialized. After examining the CD markers of the fibroblast cells, researchers at BioMed Central discovered that these cell lack "distinctive markers" confirming that these cells can be further differentiated. One example of further differentiation of dermal fibroblasts is that upon injury, dermal fibroblasts can give rise to myofibroblasts, fibroblast cells with smooth muscle characteristics. Dermal cells differentiate into myofibroblasts by
