👉 The autofluid, also known as the basal lamina fluid or interstitial fluid, is a critical component of the extracellular matrix that fills the spaces between cells in tissues. It plays a vital role in maintaining tissue structure and function by providing a medium for nutrient and waste exchange, supporting cell adhesion, and facilitating cellular signaling. Composed primarily of water, ions, and small molecules like glucose and amino acids, autofluid is constantly being produced and reabsorbed by surrounding cells, ensuring a dynamic balance that supports tissue homeostasis. This fluid is essential for the proper functioning of various tissues, including skin, bone, and muscle, as it helps maintain the microenvironment necessary for cellular activities.
