👉 The walking fluid, also known as the extracellular matrix (ECM), is a complex network of proteins and carbohydrates that surrounds and supports cells in tissues, particularly in the skin, joints, and muscles. It acts as a scaffold, providing structural integrity and facilitating cell-to-cell communication. Composed primarily of collagen, elastin, proteoglycans, and glycoproteins, the ECM plays a crucial role in maintaining tissue elasticity, strength, and hydration. It also influences cell behavior, including migration, proliferation, and differentiation, by interacting with cell surface receptors. This dynamic matrix is essential for various physiological processes, such as wound healing, tissue repair, and maintaining the overall health of connective tissues.
