- Cytokines, growth factors, and chemokines from PAN-Seratech.
- Cytokines are becoming increasingly important in cell biology. Sugar-containing proteins have regulating functions for the growth and differentiation of body cells. Many cytokines also play an important role in immunological reactions, and they are then generally referred to as mediators.
Cytokines, which primarily trigger and/or regulate the proliferation and differentiation of target cells, are known as growth factors. These proteins that are transferred as signals from one cell to another, and therefore relay information, play a role mainly in the development of multi-cellular organisms. Growth factors are either secreted i.e. released by the cells into the environment or they are membrane-bound.
