Decellularized extracellular matrix as a drug delivery carrier

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Drug Delivery Systems

Background:

• Tissue engineering aims to mimic native tissues using biomaterials to promote cell growth and differentiation.
• Decellularized extracellular matrix (dECM) offers a complex, native-like environment but can be altered during decellularization.
• Recent research focuses on utilizing dECM as a scaffold for controlled release of therapeutic agents.

Purpose of the Study:

• To review current strategies for incorporating therapeutic agents into dECM for controlled release.
• To highlight the advantages of different incorporation methods for modulating drug release profiles.
• To discuss factors influencing the release kinetics of bioactive molecules from dECM carriers.

Main Methods:

• Review of literature on dECM-based drug delivery systems.
• Analysis of methods including hydrogel encapsulation, bulk absorption, and affinity-based conjugation.
• Examination of factors affecting drug release, such as crosslinking density and degradation rate.

Main Results:

• Multiple strategies exist for incorporating therapeutic agents into dECM.
• Methods vary in their ability to control release kinetics, from burst release to sustained delivery.
• Interactions between biomolecules and dECM components, like glycosaminoglycans, influence release.

Conclusions:

• dECM is a versatile platform for developing advanced drug delivery systems in regenerative medicine.
• Tailoring incorporation methods allows for precise control over therapeutic agent release.
• Further research can optimize dECM-based carriers for enhanced therapeutic efficacy.
