Sejtmátrix

Sejtmátrix, often translated as extracellular matrix or ECM, is a complex network of molecules that provides structural and biochemical support to surrounding cells. It is a non-cellular component present within all tissues and organs. The composition of the sejtmátrix varies significantly depending on the tissue type and its function. Key components include structural proteins like collagen and elastin, proteoglycans, glycoproteins, and various growth factors.

The primary functions of the sejtmátrix are diverse. It plays a crucial role in maintaining tissue architecture and providing mechanical strength, resisting tensile forces and compression. Furthermore, the sejtmátrix acts as a reservoir for signaling molecules, influencing cell behavior such as proliferation, migration, and differentiation. It also participates in cell adhesion, allowing cells to attach and interact with their environment.

Disruptions in sejtmátrix composition or organization are implicated in a wide range of diseases, including cancer, fibrosis, and inflammatory conditions. Research into the sejtmátrix is an active area, focusing on understanding its intricate roles in health and disease and exploring potential therapeutic interventions targeting its components.
