Tissue engineering constructs guide cell behavior for regeneration. Bottom-up and integrative approaches offer superior control for designing advanced biomimetic scaffolds.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Tissue Engineering
Background:
- Successful tissue regeneration requires balanced cell-matrix interactions within 3D constructs.
- Understanding normal and regenerative tissue processes informs the design of biomimetic scaffolds.
- Instructive cues are essential for guiding cellular behavior in engineered tissues.
Purpose of the Study:
- To review key events and players in tissue regeneration.
- To highlight the importance of multiscale features in biomimetic structures.
- To compare top-down, bottom-up, and integrative tissue engineering approaches.
Main Methods:
- Overview of cellular and matrix dynamics in normal and regenerative tissues.
- Analysis of instructive cues for biomimetic construct design.
- Comparative review of fabrication strategies: top-down, bottom-up, and integrative.
Main Results:
- Bottom-up and integrative approaches enable greater control over multiscale features.
