Fabricating tissue engineering scaffolds for simultaneous cell growth and drug delivery

Area of Science:

• Biomaterials Science
• Tissue Engineering
• Drug Delivery Systems

Background:

• Tissue engineered constructs serve as temporary substitutes for damaged or lost tissues.
• Scaffolds mimic the extracellular matrix (ECM), incorporating biomolecular cues essential for cell growth and function.
• Integrating drug delivery within scaffolds protects therapeutic agents and enables sustained release for effective therapy.

Purpose of the Study:

• To review formulation and fabrication methods for tissue engineering scaffolds with drug delivery capabilities.
• To describe the tissue engineering features of various scaffold types, including films, hydrogels, fibers, and microspheres/nanospheres.
• To examine fabrication techniques and drug encapsulation methods for these advanced scaffolds.

Main Methods:

• Review of literature on scaffold formulation and fabrication.
• Analysis of drug encapsulation strategies for sustained release.
• Description of tissue engineering applications for films, hydrogels, fibers, and microspheres/nanospheres.

Main Results:

• Various scaffold types (films, hydrogels, fibers, microspheres/nanospheres) can be engineered for drug delivery.
• Fabrication techniques and drug encapsulation methods are crucial for scaffold performance.
• Successful integration of drug delivery enhances the biomimetic and therapeutic potential of tissue engineering scaffolds.

Conclusions:

• Tissue engineering scaffolds with drug delivery are vital for mimicking the ECM and providing controlled release of biomolecules.
