IL-7 is a hematopoietic growth factor that stimulates T-lymphocyte differentiation and maintains homeostasis of naive T-cells and memory T-cells. It is possible that human IL-7 is involved in the regulation of postnatal development of B-lymphocytes. IL-7 plays an important role in the development of secondary lymphoid organs.
