Cytokine signaling to the cell cycle

Abstract

The proliferation of many myeloid and lymphoid cell populations is directly controlled by cytokine growth factors acting through a related family of cytokine receptors. This regulation implies that the signaling pathways activated by cytokine receptors must communicate with mechanisms that control mammalian cell cycle progression. Evidence for how these signaling pathways promote hematopoietic cell proliferation is considered along with their likely targets among the cell cycle regulators.
