Abstract
Introduction and hypothesis
Xenogeneic (porcine) extracellular matrix (ECM) scaffolds have been suggested as ideal biomaterials for regeneration medicine; however, ECM prepared from different tissue sources has shown distinctive biological properties. Therefore, a comprehensive understanding of biological characteristics of different tissue-derived ECM is essential in the design of scaffolds for pelvic reconstruction.
Methods
We compared the biological properties of ECM derived from different tissue sources of Bama miniature pigs as a pelvic biological patch in terms of histological structure, water absorption ability, biodegradation ability, mechanical properties, antimicrobial activity, and biocompatibility in vitro.
Results
Different ECM scaffolds have distinct structural differences, and all have good biocompatibility, and UBM exhibited better water uptake ability (above 500%), anti-biodegradation ability, mechanical properties, antimicrobial activity, and stem cell attachment properties than other tissue-derived ECM.
Conclusions
Porcine UBM might serve as an ideal pelvic biological patch.
