Seeing a cell commit suicide to protect the body from cancer

The new images show the exact speed at which a cell commits suicide to protect the body from disease.

The video shows death spreads through a cell at a speed of 0.03 mm per minute.

The cells, which can be up to 0.1 mm in diameter, are often killed for the common good, such as to prevent the development of cancer or the spread of viruses. This process is known as apoptosis.

Such deaths are triggered by a signal that is activated inside a cell that then spreads like a "wave" with the self-destruction of a part of the cell that causes the same death in another place, like a forest fire, according to a US study. .

Experts previously thought that cell death was spread by diffusion, which is the movement of substances from an area where they are in a high concentration to a region where their concentration is low.

However, the study's researchers argue that a cell death rate of 0.03 mm is too fast to be reduced to diffusion and, instead, must be caused by a chemical trigger.

WHAT IS APOPTOSIS?

Programmed cell death, known as apoptosis, occurs when a cell commits suicide.

The proteins in the cell break down the components that are essential for survival, as well as the enzymes that activate and destroy the genetic material of the cell.

Then, the cell contracts and sends signals for the components of the immune system to clean them.

In the uterus, the fingers of the fetus' hands and feet are webbed, with apoptosis occurring to separate them into 10 digits.

When excess cells are produced in the brain during a person's development, apoptosis occurs, so the remaining cells can function well.

Anti-cancer medication and radiation therapy trigger apoptosis in diseased cells.

How the investigation was carried out

The researchers, from Stanford University, analyzed the fluid cells in frog eggs.

This fluid contained a bright green protein that appeared as bright spots.

The fluid was placed in a tube, which was then placed in an extract of a cell that had already undergone programmed death. The deceased cell had an added red dye.

As the components of the fluid self-destructed, the green dots disappeared, demonstrating the speed of death as it spread through the cell.

Then, the investigators filmed this wave of death & # 39; that spread through an egg.

The images suggest that as death spread, the cell would turn red.

The findings were published in the journal Science.
