Cytokines, Chemokines, & Growth Factors

Cytokines, chemokines, and growth factors are produced in the body to direct functions such as cell growth, differentiation, and proliferation. These molecules are typically produced in low abundance but pack a powerful punch in terms of their effects on cell signaling pathways, such as triggering inflammatory or immune responses. In laboratory research, cytokines, chemokines, and growth factors can be used as reagents in cell culture growth. They are also often the focus of in vitro or in vivo assays aimed toward delving into their mechanisms of action. There are hundreds of types of cytokines, chemokines, and growth factors, and they are available for many species types. Considerations in selecting a product include purity and the quantity needed for the intended experimental use.
