👉 The ISP fluid, or Interstitial Space Protein Fluid, is a complex mixture of proteins and other macromolecules that exist in the interstitial spaces between cells within tissues. Unlike the more familiar intracellular fluid, which is primarily composed of water and dissolved solutes, ISP fluid is characterized by its unique composition and physical properties, including a higher concentration of proteins and a more disordered state. This fluid plays a crucial role in maintaining tissue homeostasis, facilitating cell signaling, and supporting cellular processes such as migration and differentiation. Its dynamic nature allows it to adapt to various physiological conditions, making it essential for the proper functioning of multicellular organisms.
