Bioactive materials to control cell cycle

Many of the present generation biomaterials are still based upon the early concept that implantable materials should be bioinert and therefore designed to evoke minimal tissue response, if none. However, a growing body of clinical data demonstrates that the long survivability of these materials is hampered by high rates of failure, which is primarily attributed to interfacial instability. It has therefore become understood that this approach is not optimal. Modern approaches implicate the use of biomaterials that can actively interact with tissues and induce their intrinsic repair and regenerative potential. This involves control over the cell cycle, the molecular framework that controls cell proliferation and differentiation. Class A bioactive glass-ceramic materials were the first materials shown to endorse these properties and, depending upon the rate of resorption and release of ions, can create chemical gradients with specific biological actions over cells and tissues. Optimising this bioactive regenerative capacity of Bioactive glass-ceramics offers great hope for producing biomaterials that can stimulate growth, repair, and regeneration of any human tissue.
