In this study, we have investigated the proliferative response of human dermal fibroblasts isolated from normal and psoriatic individuals to different cytokines. We found that IL-1, TNF (α) and EGF are stimulatory whereas IFN « and 1 both showed inhibitory activity on fibroblast proliferation. IL-6 a more recently described cytokine, showed no detectable effects on cell proliferation. Inve...

Transforming growth factor alpha (TGF alpha) stimulates DNA synthesis in adult rat hepatocytes, and plays a physiological role after partial hepatectomy by an autocrine mechanism. Somatostatin (SS-14) is a potent inhibitor of gastrointestinal function and inhibits proliferation in various cell types. We examined the proliferative effect of TGF alpha and the inhibitory effect of SS-14 on hepatoc...

We previously demonstrated that cells isolated from the mesenchymal region of the human amniotic membrane (human amniotic mesenchymal tissue cells, hAMTC) possess immunoregulatory roles, such as inhibition of lymphocyte proliferation and cytokine production, and suppression of generation and maturation of monocyte-derived dendritic cells, as reported for MSC from other sources. The precise fact...
