Reduced growth of dermal fibroblasts from chronic venous ulcers can be stimulated with growth factors
Carotid Artery, Internal
Our data demonstrate that wound-fb proliferate at a slower rate and are morphologically distinct from normal-fb. These characteristics are typical of aged or senescent cells. This decreased growth can be stimulated by growth factors basic fibroblast growth factor, epidermal growth factor, and interleukin-1 beta. Slowed growth may be partially responsible for the defect in healing of venous stasis ulcers. Furthermore, we believe that in some patients ulcer healing may be improved by exogenous provision of specific growth factors.
