Endometrial regeneration and the role of the extracellular matrix: mechanisms, challenges, and future perspectives

Endometrial regeneration is a cornerstone of reproductive health, with the extracellular matrix (ECM) playing a pivotal role in tissue repair, regeneration, and fertility restoration. Dysregulated ECM remodeling is at the heart of many debilitating conditions, including infertility, endometriosis, Asherman's syndrome, and uterine fibroids, all of which disrupt the delicate balance necessary for effective endometrial regeneration. This review presents a cutting-edge analysis of ECM dynamics, emphasizing its central role in the endometrial regeneration process and highlighting novel ECM-targeted therapies that hold transformative potential for addressing these complex disorders. We focus on emerging strategies such as stem cell-based therapies, growth factor modulation, matrix metalloproteinase inhibition, and peptide-based interventions that precisely regulate ECM composition to promote healing and restore functionality to the endometrium. Revolutionary technological advancements, including 3D bioprinting, biocompatible ECM scaffolds, and organoid models, are providing new avenues for personalized therapeutic approaches aimed at optimizing ECM interaction and enhancing regenerative outcomes for individual patients. Despite these promising developments, significant challenges remain in evaluating the long-term safety and efficacy of ECM-targeted treatments. This review also identifies critical knowledge gaps, particularly in understanding the molecular mechanisms governing ECM remodeling in the endometrial context, urging further exploration to unlock the full therapeutic potential of ECM-based regeneration strategies. Through precise modulation of ECM dynamics, this research sets the stage for innovative treatments that could revolutionize the management of uterine dysfunction and significantly enhance fertility restoration.
