Tukikalvot

Tukikalvot, often translated as "support membranes" or "basement membranes," are thin layers of extracellular matrix found in a variety of biological tissues. They play a crucial role in the structure and function of many organs and tissues. These membranes are primarily composed of proteins, such as collagen and laminin, along with proteoglycans and glycoproteins.

One of the main functions of tukikalvot is to provide structural support, anchoring cells and separating different tissue types. They act as a physical barrier, regulating the passage of molecules and cells between tissues. Tukikalvot are also involved in cell adhesion, helping cells to attach to their surroundings and maintain their position. Furthermore, they are important in cell signaling, influencing cell behavior and differentiation.

In the kidneys, tukikalvot form part of the filtration barrier in the glomeruli, essential for the removal of waste products from the blood. In the nervous system, they surround nerve fibers, contributing to the insulation and protection of neurons. Muscle cells and epithelial cells are also enveloped by tukikalvot, which are vital for their proper function and regeneration. Disruptions to tukikalvot can be associated with various diseases, highlighting their fundamental importance in maintaining tissue integrity and health.
