The existence of orderly structures like tissues and organs is possible by cell adhesion, a process where cells attach to neighbouring cells and extracellular matrix. The extracellular matrix, composed of collagens, elastin, proteoglycans, and glycoproteins, serves as a storehouse for signaling factors. Tissue disruption may require the use of implants for reconstitution, detailing the host response and surface properties modifications.
The existence of orderly structures, such as tissues and organs is made possible by cell adhesion, i.e., the process by which cells attach to neighbouring cells and a supporting substance in the form of the extracellular matrix. The extracellular matrix is a three-dimensional structure composed of collagens, elastin, and various proteoglycans and glycoproteins. It is a storehouse for multiple signalling factors. Cells are informed of their correct connection to the matrix via receptors. Tissue disruption often prevents the natural reconstitution of the matrix. The use of appropriate implants is then required. This review is a compilation of crucial information on the structural and functional features of the extracellular matrix and the complex mechanisms of cell-cell connectivity. The possibilities of regenerating damaged tissues using an artificial matrix substitute are described, detailing the host response to the implant. An important issue is the surface properties of such an implant and the possibilities of their modification.
