Transforming Growth Factors Definition
Cytokines in the blood circulation that attach to the surfaces of cell membranes. Transforming growth factor alpha (TGF-alpha) stimulates the cells to grow, divide, and differentiate (cell proliferation).
Lymphocytes and macrophages produce TGF-alpha. TGF-beta stimulates interleukin 1 (IL-1) production and blocks the response of lymphocytes in the inflammatory process. Lymphocytes, macrophages, and platelets secrete TGFs.
