IGF-IR in dermal fibroblasts. A: Protein lysates from quiescent cells were analysed by Western blot using a specific antibody against IGF-IR. B: To ensure equal loading β-actin was also used. C: The graph represents the change in IGF-IR between MDF and FDF cell strains (n = 3 for each). Error bars = SEM. No statistical significant difference was demonstrated between the cell types.
