FAQs - Growth Factors and Cytokines

Growth factors are signaling molecules that regulate cell proliferation, differentiation, and migration. "Cytokine" was first used to define a subset of growth factors influencing immune and hemopoietic cells. However, it is now clear that cytokines can act on many different cell types and have diverse effects on proliferation and differentiation. Therefore, "cytokine" is now used more broadly and interchangeably with "growth factor."

Cytokines are added to cell cultures to promote proliferation and to maintain cells in the desired state or lineage by regulating proliferation and differentiation.

Cytokines and growth factors ensure differentiation and proliferation of the cell(s) of interest. They are critical cell culture media components, particularly when serum-and animal-free conditions or defined media are required.

Growth factors bind to receptors on the surface of cells and initiate signaling cascades that ultimately up- or downregulate genes involved in cell proliferation and growth.
