Description

IL-7 is an important cytokine for the growth, survival, and differentiation of T, B, and NK cells. The heterodimer formed by IL-7 and hepatocyte growth factor (HGF) is a precursor B cell growth stimulating factor. Studies on gene knockout in mice have shown that IL-7 plays a crucial role in the survival of lymphocytes. IL-7 stimulates pluripotent stem cells to differentiate into lymphoid progenitor cells.
