Abstract
Different types of stem cells are targeted by a number of cytokines that alter proliferation, differentiation, or other properties of stem cells. Stem cells are known to express various cytokine genes. As IL-12, IL-14, G-CSF, and GM-CSF expression is lost after the differentiation of MSCs, these factors might have major contribution to pluripotency. Several other cytokines that are produced by immune cells, frequently target stem cells. Modulation of stem cell functions by cytokines can be a cause of various diseases including cancer. Stem cells can show immunosuppressive properties by a number of mechanisms. MSC-induced immunosuppression is often mediated by IFN-γ, TNF-α, IL-1α, or IL-1β. In co-culture experiments, MSCs were able to control T cells IL-2 response, or, dendritic cells TNF-α and IL-10 secretion. MSCs are also known to cause decreased interferon γ (IFN-γ) and increased IL-4 production by immune cells. However, the outcome in most of the cases depends on the presence of various factors that might synergize or antagonize with each other.
