How do cells of neoplastic
tumors obtain oxygen and
nutrients and release wastes?
Introduction
Introduction
The cancerous cells are commonly called as neoplastic cells. As we know the cancerous cells continue to divide infinitely if it gets suitable environment and nutrition such as oxygen, glucose as the energy source. They are undifferentiated cells which arise by continuous proliferation and uncontrolled cell division.
Various studies show that cancer cells change their surrounding environment which is called as cellular micro-environment according to their need. By changing the micro-environment they get enough supply of oxygen and nutrients for their continuous proliferation. To get the enough supply of oxygen through blood cancer cells develops their own blood vessels through which it get their nutrients.
Angiogenesis: If we split the term angiogenesis we’ll get to know the real meaning of the term. “Angio” means the blood vessels and the “genesis” means the generation. So, the Angiogenesis means the formation of new blood vessels by cancerous cells. This process is very crucial in the metastasis of tumor cells. To restrict the various types of cancer, researchers usually hinder the angiogenesis process so that tumour cells cannot get enough oxygen supply and nutrients and ultimately die off.
