Enhancing diaphragmatic defect repair and regeneration: How biomaterials leading the way to progress?

Abstract

Physicians encounter significant challenges in dealing with large diaphragmatic defects in both pediatric and adult populations. Diaphragmatic hernias, such as Morgagni, Bochdalek, and Hiatus hernias, can result in congenital lesions that are often undiagnosed until the appearance of symptoms (bleeding, anemia, and acid reflux). Therefore, substantial potential exists for developing tissue‐engineered constructs as novel therapeutic options in clinics. Recent research indicates promising mid‐term performance for both natural and synthetic materials. However, studies exploring their application in diaphragm regeneration are limited and remain in the early research stages. Additionally, further investigation is required to address the constraints in human tissue supply for clinical implementation. This article comprehensively reviews the role of biomaterials in diaphragmatic tissue repair and regeneration. It emphasizes biomaterials, including biomimetic polymers used in technological solutions. This summary will enable researchers to critically assess the capability of existing natural biomaterials as essential tissue‐engineered patches for clinical use.
