Is it possible to grow a cell that never dies?

No, cells die, and there is no such thing as eternal death in the true sense, but cancer cells are so-called cells that never die, and because they multiply quickly, the glycoproteins on the cell membrane are reduced, so there is no contact inhibition, and they can multiply wirelessly, but they are not immortal.

I think that you can only prolong the survival time of cells indefinitely, but you can't achieve eternal death. A cell that "never dies" cannot be called a living cell, and a living cell is "alive" because it has a metabolism. From Lao Ma's philosophy, there is no static thing that always exists, just like a person who lives forever cannot be called a person, closer to a "monster" or a "god".

Of course, we can also design in our minds a never-apoptotic cell that can update the structure at any time through technical means, but can the cell after each update and structure replacement be called a cell?

No, there is a limit to the replication and multiplication of cells.

One is impossible, you can culture a dish of cancer cells, so that it is still feasible to pass it continuously, do not contaminate it

The nucleus depends on the cytoplasm for nutrients, and without the cytoplasm, the nucleus dies. The expression of cell function depends on the genetic material in the nucleus, and the genetic material (DNA) in the nucleus of an individual of the same species is the same, so if the nucleus of another cell is transplanted, the expression function can be the same as the original.

There are many theories about the origin of mankind that have been controversial. However, it is still the theory of evolution, and at the same time, there are many inferences in the theory of evolution, and most people's perception is that human beings are like other animals from low to high from aquatic to terrestrial. The birthplace of the first human ancestors is yet to be verified.

The cause of cell growth, senescence and death has not yet been fully understood (otherwise rejuvenation would be easy to achieve). There are also many theories about this. Cell growth is accompanied by countless biochemical reactions, all of which have the potential to affect him, which is also the wonder of life.

Putting aside those theories, there is always a loss of what has been used, and quantitative changes cause qualitative changes. Cells are repaired while they are lost, and they die if they can't be replaced.

You're in the philosophical category...... aren't you?When cells die, they die, and it seems impossible for apoptotic cells to regenerate!

Genna Green should only stain living cells.

This is the principle of early mitochondrial staining of Gennagreen staining:

Janus Green B, also known as Jannus Green B, is a live-cell dye that specifically stains mitochondria, and the cytochrome oxidase in the mitochondria keeps the dye in an oxidized state (i.e., the colored state) blue-green, and the dye is reduced in the surrounding cytoplasm to become colorless. Thus, the mitochondria in living cells can be made to appear blue-green while the cytoplasm is close to colorless. Mitochondria can remain active for several hours in Gennagreen Yusong dyeing solution, and through staining, the morphology and distribution of living mitochondria can be observed under a high-powered microscope.

No. Jianna Green Jianna Green, that is, Janus Green B dye, was originally also translated as Jenna Cons Pez Green B.

Chinese alias] Kenna Green ; Jenners Green; Diazine green.

Synonyms: janus green; diazine green；diazine green s 。

Molecular Formula: C30H31ClN6 Molecular Weight.

It is often used as a mitochondrial specific in vivo stain.

The cytochrome oxidase enzyme in the mitochondria keeps the dye in an old oxidized state (i.e., the colored state) and is blue-green and colorless, while the dye is reduced in the surrounding cytoplasm and becomes colorless.

Antibiotics are a class of secondary metabolites with anti-pathogen or other activities produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants in the course of life, and can interfere with the development and function of other living cells. As for whether it will kill the cells you culture, it depends on the type of antibiotic you use and the cells you culture, which has no effect on animal and plant cells.

It depends on what cells you raise. However, generally speaking, rearing cells refer to animal and plant cells, and in order to prevent contamination, adding antibiotics is a routine operation, and there is generally no problem in following the standard operation. Of course, if you want to make microorganisms, you have to do it according to your needs, and you need to choose according to the actual situation.

Dead cells are cells that have no ability to live and cannot convert substances and metabolize their abilities, while living cells have the ability to live and can convert materials and abilities. There are many types of cell products, which can be things that are not used by themselves but can be used by other cells (such as lactic acid), or they can be substances that are toxic to both themselves and other cells (such as urea).

Dead cells are cells that can no longer metabolize normally, and living cells are vice versa. There are many cell products, such as breast cells can secrete milk, liver cells can make liver glycogen, etc.

Judgment is made based on the vital signs of the cells. For most cells, trypan blue can be identified by staining, which cannot penetrate the plasma membrane of living cells, so all cells that are colored in the microscopic examination after staining are dead cells, and vice versa. The blue stain can also be used for the identification of dead and live cells, using the characteristics of continuous oxidative metabolism of living cells, living cells can oxidize the blue to a colorless oxidation state, in the microscopic examination, the dark blue is the dead cells, and the light or colorless cells are the living cells.

The staining method is suitable for the identification of dead and alive most cells. For plant cells, live-dead identification can be performed by plasma-wall isolation assays. Only the plasma membrane of surviving plant cells has the ability to selectively permeabilize, and the phenomenon of plasma wall separation can occur.

Normal cells can replicate themselves when they are well nourished. From this, the physiological state of most cells can be determined. Some of the mutated cells will only increase in size when the nutrients are sufficient, and will not replicate themselves.

It also dies, the nucleus is the center that controls the cell, and many functions, such as the most important respiration, are also related to the nucleus (respiratory enzymes and the like can only be synthesized through the nucleus), so they also die.
