title: Early events in lymphopoiesis: the role of interleukins 1 and 7.
abstract: This article summarizes evidence that interleukins 1 and 7 play a critical role in the early stages of lymphopoiesis. IL-1 has been demonstrated to be identical to the growth factor previously termed haemopoietin-1 and appears to cause the growth of haemapoietic stem cells. Interleukin-7, originally described as a pre-B-cell growth factor, also has proliferative activity on T cells. It is proposed that IL-7 acts on lymphoid stem cells.
