tumorvasculatuur

Tumorvasculatuur refers to the network of blood vessels that supply a tumor. These vessels are crucial for tumor growth and survival, as they provide oxygen and nutrients and facilitate the removal of waste products. Unlike normal blood vessels, tumor vasculature is often disorganized, leaky, and inefficient. This abnormal structure can lead to areas of hypoxia (low oxygen) within the tumor, which can promote further tumor growth and metastasis.

The formation of new blood vessels in a tumor is known as angiogenesis. Tumors release signaling molecules that stimulate nearby blood vessels to grow and extend into the tumor mass. This process is essential for tumors to grow beyond a very small size. The characteristics of tumorvasculatuur, such as its density, permeability, and tortuosity, can significantly impact tumor behavior and response to therapy.

Understanding tumorvasculatuur is important in cancer research and treatment. Targeting these abnormal blood vessels, a strategy known as anti-angiogenic therapy, is one approach to slow or stop tumor growth. By disrupting the blood supply, these therapies aim to starve the tumor of its essential resources. However, the complex and adaptable nature of tumorvasculatuur presents challenges, and resistance to anti-angiogenic therapies can develop. Further research continues to explore the intricate details of tumorvasculatuur to develop more effective cancer treatments.
