A cytokine derived from bone marrow cells that causes proliferation of B and T lymphocytes.

interleukin-7 (IL-7)

a cytokine produced by bone marrow stromal cells that causes lymphoid stem cells to differentiate into progenitor B and T cells and stimulates the killing of foreign cells by T cells and monocytes.

IL7

A gene on chromosome 8q12-q13 that encodes interleukin-7, a hematopoietic growth factor which stimulates the proliferation of lymphoid progenitors, including both B and T cells. It forms a heterodimer with hepatocyte growth factor to act as a pre-pro-B-cell growth-stimulating factor. It is also a cofactor for V(D)J rearrangement of the T-cell receptor beta during early T-cell development. IL7 is produced locally by intestinal mucosal cells, and may act as a regulatory factor for intestinal mucosal (GALT) lymphocytes.

in·ter·leu·kin-7

(in'tĕr-lū'kin)
A cytokine derived from bone marrow cells that causes proliferation of B and T lymphocytes.

interleukin-7

A CYTOKINE produced by the bone marrow stromal cells responsible for the proliferation of B cell precursors, helper and cytotoxic T cells and activated mature T cells.
