Abstract

The extracellular matrix (ECM) is a non-cellular three-dimensional structure present in all tissues that is essential for the intestinal maintenance, function and structure, as well as for providing physical support for tissue integrity and elasticity. ECM enables the regulation of various processes involved in tissue homeostasis, being vital for healing, growth, migration and cell differentiation. Structurally, ECM is composed of water, polysaccharides and proteins, such as collagen fibers and proteoglycans, which are specifically arranged for each tissue. In pathological scenarios, such as inflammatory bowel disease (IBD), the deposition and remodeling of the ECM can be altered in relation to the homeostatic composition. IBD, such as Ulcerative colitis and Crohn’s disease, can be differentiated according to ECM alterations, such as circulating levels of collagen, laminin and vimentin neoepitopes. In this context, ECM presents particularities in both physiological and pathological processes, however, exploring methods of tissue decellularization is emerging as a promising frontier for new therapeutic interventions and clinical protocols, promoting the development of new approaches to intestinal diseases.

Keywords: Extracellular matrix; Inflammatory bowel disease; Decellularization protocols; Regenerative medicine; Intestine

Core Tip: Regenerative medicine provides a promising perspective in the treatment of inflammatory bowel diseases (IBD) by targeting tissue repair. The development of decellularization techniques to produce scaffolds that mimic the native environment of the intestine is crucial to the advances in this field. This article addresses how research focused on the extracellular matrix in IBD tissues and studies ways to improve regenerative therapies that represent fundamental steps towards furthering the efficacy and safety of IBD treatments.
