Although insulin is a much weaker mitogen [2] than insulin-like growth factors (IGFs), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF), insulin has a very specific mitogenic action that in fact modulates cellular responsiveness to all other growth .
