The extracellular matrix (ECM) is a dynamic component of the tumor microenvironment that plays a crucial role in cancer progression. The ECM, a complex network of macromolecules, influences cancer development by promoting cellular transformation, metastasis, and the generation of a tumorigenic microenvironment. It regulates various cellular behaviors through its physical, biochemical, and biomechanical properties, including cell migration, signaling, and tissue architecture. Abnormal ECM dynamics, often seen in cancer, lead to disorganization and altered ECM properties, which can promote cancer progression by deregulating stromal cell behavior, facilitating angiogenesis, and enhancing tumor growth. The ECM is essential for maintaining tissue polarity and architecture, and its disruption can lead to cancer cell invasion. Abnormal ECM also contributes to the formation of a tumor microenvironment by influencing stromal cells, including immune cells and fibroblasts. The ECM's role in tumor angiogenesis and lymphangiogenesis is significant, as it supports the growth and spread of cancer cells. Additionally, the ECM plays a key role in tumor-associated inflammation by influencing immune cell behavior, including infiltration, differentiation, and activation. The ECM is also crucial for the development of premetastatic and metastatic niches, where cancer cells can survive and proliferate. Abnormal ECM dynamics can promote the formation of these niches by altering the ECM composition and stiffness, which in turn facilitates cancer cell colonization and metastasis. Understanding the regulation of ECM dynamics and its impact on cancer progression is essential for developing new therapeutic strategies targeting the tumor niche. The ECM's dynamic nature and its ability to influence various cellular processes make it a critical target in cancer research and treatment.The extracellular matrix (ECM) is a dynamic component of the tumor microenvironment that plays a crucial role in cancer progression.
