Abstract: Epidermal growth factor (EGF), which promotes epidermal regeneration and wound closure, is important for the proliferation and differentiation of epidermal and epithelial tissues in animals. Exogenous EGF is a promising therapeutic agent for wound healing, but its general use is restricted by the limited availability of this protein. in this work, we show that the transfection of mouse BALB/MK keratinocytes, which are totally dependent on EGF for growth and migration, with mature cDNA for human EGF via a retroviral vector abolished the cells requirement for exogenous EGF. the transformed cells had normal morphology and a growth rate that varied according to the source of the retroviral vector used. Keratinocyte transfection with EGF cDNA provides a time- and cost-efficient means of culturing keratinocytes and yields cells that may be useful for skin grafting.
