Overview of Human Astrocytoma Cells
Astrocytoma cells are special kinds of star-shaped cells in the brain and spinal cord. They turn cancerous and grow and divide abnormally. These cells make up a big part of brain tumors in adults. They are sorted into different levels of cancer by the World Health Organization (WHO).
Definition and Characteristics
Astrocytoma cells are part of glioma cells. They are classified into four WHO grades. Grade I is the least cancerous and grows slowly. Grade IV is the most cancerous and grows very fast.
This classification helps us understand how aggressive the tumors are and what the future might hold.
Role in the Nervous System
Astrocytes are key to keeping the blood-brain barrier strong and helping neurons work right. But when they turn into astrocytoma cells, they mess up brain functions. This shows how important astrocytes are in keeping the brain healthy or fighting disease.
