  Objective: To gain a better understanding of the Epidermal Growth Factor (EGF) Receptor (EGFR) activation, trafficking and biological response in diabetic foot ulcers (DFU), exposed to recombinant human EGF via intra-ulcer infiltration as a healing alternative. Methods: We studied by immunoelectron microscopy the intracellular localization of the EGFR and Proliferating Cell Nuclear Antigen (PCNA) in fibroblast-like cells (FLC) from granulation tissue of DFU patients, collected before and at different time points after EGF treatment. Results: EGF therapy appears to increase EGFR immunolabeling. At early time-points, EGFR labeling is observed predominantly in the nucleus, suggesting a fast EGFR internalization and nuclear translocation. Interestingly EGFR is also detected in the mito..
