Hepatozyten

Hepatozyten are the primary functional cells of the liver, making up approximately 80% of the liver's mass. These highly specialized cells are polygonal in shape and possess one or two nuclei. They are arranged in plates or cords radiating from a central vein within the hepatic lobule. Each hepatozyten is in close contact with blood sinusoids, which are small blood vessels, allowing for efficient exchange of substances.

The functions of hepatozyten are incredibly diverse and essential for maintaining homeostasis. They play a central role in metabolism, synthesizing bile, cholesterol, plasma proteins like albumin and clotting factors, and various enzymes. Hepatozyten are also responsible for detoxification, breaking down harmful substances such as drugs and alcohol, and metabolizing carbohydrates, fats, and proteins. Furthermore, they store glycogen, vitamins, and minerals.

These cells exhibit remarkable regenerative capacity, meaning they can regrow after injury. However, chronic damage can lead to their replacement by fibrous tissue, a process known as fibrosis, which can impair liver function and lead to conditions like cirrhosis. The maintenance of hepatozyten health is therefore critical for overall well-being.
