Tailoring the Interface of Biomaterials to Design Effective Scaffolds
2018
Tissue engineering (TE) is a multidisciplinary science, which including principles from material science, biology and medicine aims to develop biological substitutes to restore damaged tissues and organs. A major challenge in TE is the choice of suitable biomaterial to fabricate a scaffold that mimics native extracellular matrix guiding resident stem cells to regenerate the functional tissue. Ideally, the biomaterial should be tailored in order that the final scaffold would be (i) biodegradable to be gradually replaced by regenerating new tissue, (ii) mechanically similar to the tissue to regenerate, (iii) porous to allow cell growth as nutrient, oxygen and waste transport and (iv) bioactiv…
Porous biomaterials and scaffolds for tissue engineering
2019
In the present article, an overview of the definition of tissue engineering and scaffold requirements is reported. In particular, scaffold porosity and its relevance for several tissue target regeneration is highlighted. Different scaffold fabrication techniques are reported and explained in details, highlighting advantages and disadvantages for all of these techniques, regarding the specific final applications.
Solution-Based Processing for Scaffold Fabrication in Tissue Engineering Applications: A Brief Review
2021
The fabrication of 3D scaffolds is under wide investigation in tissue engineering (TE) because of its incessant development of new advanced technologies and the improvement of traditional processes. Currently, scientific and clinical research focuses on scaffold characterization to restore the function of missing or damaged tissues. A key for suitable scaffold production is the guarantee of an interconnected porous structure that allows the cells to grow as in native tissue. The fabrication techniques should meet the appropriate requirements, including feasible reproducibility and time- and cost-effective assets. This is necessary for easy processability, which is associated with the large …
