Kupffer Cells vs. Hepatocytes — What's the Difference?
By Tayyaba Rehman — Published on November 26, 2023
Kupffer Cells are liver macrophages that filter blood and remove debris, while Hepatocytes are liver cells that perform metabolic, synthetic, and storage functions. Both are crucial for liver functionality and health.

Key Differences
Kupffer Cells are specialized macrophages located in the liver, responsible for filtering and breaking down old red blood cells, pathogens, and other debris from the blood. Hepatocytes, on the other hand, are the main functional cells of the liver and play a pivotal role in various metabolic processes, including detoxification, protein synthesis, and the production of bile.
While Kupffer Cells are part of the immune system and act as the liver's primary defense mechanism, Hepatocytes are not directly involved in immune responses. Instead, Hepatocytes are essential for maintaining the body's metabolic balance, breaking down and storing nutrients, and producing vital proteins.
In terms of abundance, Hepatocytes make up about 80% of the liver's volume. These cells have a unique ability to regenerate, ensuring the liver can recover from damage. Kupffer Cells, although fewer in number compared to Hepatocytes, are strategically positioned along the liver's sinusoids, allowing them to efficiently filter the blood coming from the digestive tract.
Kupffer Cells primarily engage in phagocytosis, a process where they engulf and digest cellular debris, bacteria, and other foreign substances. This function is crucial for detoxifying the blood. Hepatocytes, conversely, are more versatile in their functions, handling tasks from glucose storage as glycogen to the synthesis of cholesterol and certain proteins.
To encapsulate, both Kupffer Cells and Hepatocytes are indispensable to liver function, but they serve very different roles. While Kupffer Cells focus on defense and cleaning the blood, Hepatocytes are multitaskers, handling a broad spectrum of the liver's metabolic and synthetic activities.
