umls-concept:C0021761 | skos:definition | MSH: A cytokine produced by bone marrow stromal cells that promotes the growth of B-LYMPHOCYTE precursors and is co-mitogenic with INTERLEUKIN-2 for mature T-LYMPHOCYTE activation.,CSP: produced by epithelial and mesangial stromal cells; serves as a differentiation factor for B cell early development; also supports growth of some thymocytes and T lymphocytes.,NCI: One of a group of related proteins made by leukocytes (white blood cells) and other cells in the body. IL-7 is made by cells that cover and support organs, glands, and other structures in the body. It causes the growth of T lymphocytes and B lymphocytes. IL-7 made in the laboratory is used as a biological response modifier to boost the immune system in cancer therapy. IL-7 is a type of cytokine.,NCI: Encoded by human IL7 Gene, Interleukin-7 is an important cytokine for B and T cell development. This cytokine and HGF form a heterodimer that functions as a pre-pro-B cell growth-stimulating factor. IL7 is a cofactor for V(D)J rearrangement of T cell re | lld:umls |
