The extracellular matrix (ECM) is a complex network of macromolecules that provides structural and biochemical support to surrounding cells. Various ECM components such as collagen, proteoglycans, elastin, fibronectin, glycosaminoglycans, and integrins are involved in facilitating cell adhesion, signaling, and tissue organization.
Understanding the composition, structural organization, and dynamics of the ECM is essential for unraveling its impact on cellular behavior, tissue function, and disease pathogenesis. Significant progress in high-resolution CryoEM and computational modeling techniques, such as AlphaFold, has opened new avenues for investigating previously inaccessible aspects of the ECM. Furthermore, recent advances in ECM research uncovered the intricate interplay between ECM components and cellular processes, shedding light on their involvement in cancer progression, tissue fibrosis, and regenerative medicine. Moreover, research has highlighted the potential of ECM-based biomaterials for tissue engineering and therapeutic applications.
Looking ahead, continued research in this area holds the potential for uncovering novel ECM-targeted therapies for various diseases, including cancer, cardiovascular disorders, and musculoskeletal conditions. Furthermore, ongoing investigations may lead to the development of innovative strategies for modulating ECM remodeling and promoting tissue regeneration, offering new avenues for clinical interventions.
With recent advances in CryoEM and structure prediction technologies, structural studies are poised to play a pivotal role in advancing our understanding of ECM mechanisms at an atomic level. These techniques enable detailed visualization and modeling of ECM components and their interactions, providing valuable insights into their functional roles in health and disease. This Collection welcomes submissions leveraging these state-of-the-art approaches to further explore the structural aspects of the ECM and their implications for therapeutic innovation.
