Astrocytomas originate in a particular kind of glial cells, star-shaped brain cells in the cerebrum called astrocytes.
What is a spindle cell tumor in the stomach?
The region of the viral genome (DNA in DNA tumor-viruses or RNA in RNA-tumor viruses) that can cause a tumor is called an oncogene. This foreign gene can be carried into a cell by the virus and cause the host cell to take on new properties such as immortalization and anchorage-independent growth.
The mass of cells that result from uncontrolled cell growth is called a tumor. Tumors can be benign (non-cancerous) or malignant (cancerous). Malignant tumors have the ability to invade surrounding tissues and spread to other parts of the body.
Centrioles are cylindrical structures found in animal cells that play a role in cell division by organizing the mitotic spindle. Astral rays are microtubules radiating from the centrioles that help position the spindle in the cell during division, ensuring proper chromosome segregation. Together, centrioles and astral rays work to organize and separate chromosomes during cell division.
Mitosis in animal cells is "amphi astral" because the spindle fibers, which help separate the chromosomes, are arranged in a star-like configuration at both poles of the cell. This configuration is essential for ensuring the accurate segregation of genetic material into two daughter cells during cell division.
What is a spindle cell tumor in the stomach?
Uncontrolled cell growth is usually called a tumor. When there is a condition that causes uncontrolled cell growth of abnormal cells, it is called cancer.

The region of the viral genome (DNA in DNA tumor-viruses or RNA in RNA-tumor viruses) that can cause a tumor is called an oncogene. This foreign gene can be carried into a cell by the virus and cause the host cell to take on new properties such as immortalization and anchorage-independent growth.
The two types of cell cycle genes that cause cancer cells to divide uncontrollably if mutated are called tumor suppressor genes and antioncogene
The mass of cells that result from uncontrolled cell growth is called a tumor. Tumors can be benign (non-cancerous) or malignant (cancerous). Malignant tumors have the ability to invade surrounding tissues and spread to other parts of the body.
It depends on what you mean by 'out of control', but if you mean the cell keeps can't stop dividing while carrying faulty information, it's called cancer.
Astral rays does occur in animal cells not in plant cell
Formation of Astral Rays during Cell division.
What is a spindle cell tumor in the stomach?
a mutation occurs in a cell then a tumor forms
Mitosis is not regulated in Tumor Cells -> Apexvs
