👉 The shepherd fluid, also known as the tenocyte fluid, is a specialized extracellular fluid found within the myofibroblasts of connective tissues, particularly in the skin and other organs. These myofibroblasts, which are key players in wound healing and tissue remodeling, secrete this fluid to maintain the structural integrity of the extracellular matrix (ECM). The shepherd fluid provides essential nutrients, growth factors, and signaling molecules that facilitate the migration, proliferation, and differentiation of myofibroblasts, ensuring proper tissue repair and regeneration. By regulating ECM composition and organization, the shepherd fluid plays a crucial role in balancing tissue contraction and remodeling, preventing excessive fibrosis or scarring.
