The epidermal growth factor receptor (EGFR) differentially influences the PRGF-induced expression of ECM-related proteins in human keratinocytes. Human primary keratinocytes were stimulated for 20 h with PRGF in the presence or absence of the EGFR blocking antibody cetuximab. Relative gene expression was analyzed by real-time PCR. Shown are means ±s.e.m of three stimulations (* p < 0.05, ** p < 0.01, *** p < 0.001; Student’s t-test).
