Figure 1From: Smart biomaterials - regulating cell behavior through signaling moleculesExamples of signaling molecules modulating cell behavior in bioactive materials for tissue engineering. The ability of cells to respond to the biomaterial in a controllable manner is a decisive factor in successful disease treatments using engineered implant materials. Signaling molecules involve multifunctional proteins such as growth factors and cytokines, as well as small molecules like neurotransmitters.Back to article page
