Selective enhancement of multipotential hematopoietic progenitors in vitro and in vivo by IL-20.
2003
In a search for novel growth factors, we discovered that human interleukin-20 (IL-20) enhanced colony formation by CD34 + multipotential progenitors. IL-20 had no effect on erythroid, granulocyte-macrophage, or megakaryocyte progenitors. IL-20 transgenic mice increased the numbers and cell cycling of multipotential but not other progenitors. IL-20 administration to normal mice significantly increased only multipotential progenitor cells, demonstrating that IL-20 significantly influences hematopoiesis, with specificity toward multipotential progenitors. This is the first cytokine with such specificity identified.
