Abstract

Extracellular matrix is rich in biomolecules including structural proteins, glycosaminoglycans, and small molecules that are important for the maintenance and repair of tissue. Decellularized extracellular matrix (dECM) is expected to retain these key biomolecules and makes it a promising biomaterial candidate for regenerative medicine applications. To date, dECM-particle based biomaterials have been developed to engineer over 15 tissue types or organs, with the ultimate goal of mimicking specific biological and physical properties of the native tissue. The most common scaffold types are injectable hydrogels, electrospun scaffolds and bioprinted scaffolds. The purpose of this review paper is to highlight key challenges, fabrication methods and progress made for each tissue type, along with the discussion of other elements that are integral to push dECM biomaterials towards effective and specialized tissue repair.

Keywords: Bioprinted scaffolds; Decellularized extracellular matrix; Electrospun scaffolds; Injectable hydrogels; Tissue engineering.
