Interleukin 7 (IL-7) is a protein that in humans is encoded by the IL7 gene.

IL-7 is a hematopoietic growth factor secreted by stromal cells in the bone marrow and thymus. It is also produced by keratinocytes, follicular dendritic cells, hepatocytes, neurons, and epithelial cells, but is not produced by normal lymphocytes. A study also demonstrated how the autocrine production of the IL-7 cytokine mediated by T-cell acute lymphoblastic leukemia (T-ALL) can be involved in the oncogenic development of T-ALL and offer novel insights into T-ALL spreading.
