Effects of Granulocyte-Macrophage Colony-Stimulating Factor on Neuronal Senescence in Ultraviolet Irradiated Skin.

Ultraviolet (UV) irradiation affects neuronal structures of the skin and accelerates skin aging. Cytokine cascades in keratinocytes after UV irradiation may result in a paracrine inhibitory effect on nerve cells. The purpose of the present study was to determine the direct effect of cytokines induced by UV radiation on nerve cells in terms of neuronal senescence.

Do IL-3/GM-CSF effect on the myofibroblastic differentiation of human adipose derived stromal cells?

Background: Capsular contracture is an incurable complication after silicone-based implant surgery. Myofibroblast is the predominant cell in the contracted capsule. We hypothesized that human adipose derive stromal cells (hASCs) together with fibroblast may show a similar phenotypic characteristics of myofibroblast after the treatment of inflammatory cytokines in vitro.
