169 Polymer Scaffolds
Polymer or polymeric scaffolds refer to the scaffolds that are constructed from polymer materials.
Scaffolds are used for tissue engineering, and their function is to direct the growth of cells migrating from surrounding tissue (tissue conduction) or the growth of cells seeded within the porous structure of the scaffold. Many natural and synthetic biodegradable polymers, such as collagen, poly(α-hydroxyesters), and poly(anhydrides), have been widely and successfully used as scaffold materials due to their versatility and ease of processing.
There are different forms of polymer scaffolds: porous matrices, with a solid foam-like structure (Figure 169.1a), fiber net matrices (Figure 169.1b ...
