Extraglomerular mesangial cell thickening is a medical condition affecting the kidneys. This article breaks down what it is, its causes, symptoms, diagnosis, treatments, and more
Extraglomerular mesangial cells are specialized cells located in the kidneys. They are found outside the glomeruli, which are tiny filtering units in the kidneys responsible for removing waste from the blood. These cells help support the structure of the kidneys and maintain proper blood flow.
Mesangial cell thickening refers to the increase in the size or number of these mesangial cells. When these cells become thickened, it can disrupt normal kidney function, leading to various health issues. This condition is often associated with kidney diseases and can impact how well the kidneys filter blood.
Pathophysiology
Structure
Mesangial cells are part of the kidney’s support system. They provide structural stability to the glomeruli and help regulate blood flow. When these cells thicken, the structural integrity of the glomeruli can be compromised, affecting kidney function.
Blood Supply
The kidneys receive a rich blood supply to efficiently filter blood. Extraglomerular mesangial cells play a role in regulating this blood flow. Thickening of these cells can alter blood dynamics, potentially leading to hypertension (high blood pressure) and reduced kidney efficiency.
Nerve Supply
Nerve signals help regulate kidney functions, including blood flow and filtration rates. Thickened mesangial cells may interfere with nerve signaling, further impacting kidney performance and overall health.
Types of Mesangial Cell Thickening
- Focal Thickening: Affected areas are scattered throughout the kidneys.
- Diffuse Thickening: Thickening occurs uniformly across the kidneys.
- Segmental Thickening: Only specific segments of the kidney tissue are affected.

Mesangial cell thickening can result from various factors, including:
- Diabetes
