Scaffolds from biomaterials: advantages and limitations in bone and tissue engineering

Nowadays, there has been immense progress in developing materials to support transplanted cells. Nevertheless, the complexity of tissues is far beyond what is found in the most advanced scaffolds. This article reviews the types of biomaterials and their resulting scaffolds in the bio-engineering of bone and tissues by presenting an overview of the characteristics of ideal scaffold in tissue engineering along with types of scaffolds and examples of previous studies where these scaffolds have been applied. The advantages of scaffolds, and the three-dimensional culture system and its used commercially available scaffold is presented. Challenges encountered in the application of these scaffolds in bone and tissue engineering is also highlighted. Used method was by acquisition of materials through Google scholar, Science direct, PubMed and University library archives. Proper knowledge of the above highlighted facts will go a long way in re-addressing the production of scaffolds for bone and tissue engineering. With the proliferation of innovative applications in bioactive glasses and glass ceramics, the greater need for specific understanding of cell biology with emphasis on cellular differentiation, cell to cell interaction and extracellular matrix formation in engineering of bone and tissues becomes inevitable. This will enhance scaffold production, bone regeneration and transplantation outcome.
