What is the process by which a skin cell becomes a nerve cell

During cell differentiation, their DNA is more tightly encased, so genes that are no longer needed or should not be expressed are blocked.

DNA is tightly wrapped around a protein called a histone, and then the gene is tagged with a methyl group, preventing the mechanism of protein expression in the cell from approaching them. Several studies have shown that enzymes capable of removing methyl groups are critical to the success of nuclear transplantation. But they are not the only conditions needed for a successful nuclear transfer.

In order to truly harness the power of oocytes, scientists still need to learn how to direct the development of regenerative stem cells and guide them to form specific tissues. Stem cells, especially those derived from embryos, spontaneously form multiple cell types, but controlling development to produce a single type of cell has proven to be more difficult. While some research teams have been able to generate an almost pure population of nerve cells from embryonic stem cells, no one has been able to concoct a formula to guide the direction of cell differentiation, such as differentiation into a pure population of dopamine-secreting nerve cells to replace those missing in Parkinson's disease.

Scientists are only beginning to understand how signals interact to guide a cell to its ultimate fate. Decades of research in developmental biology have provided a beginning: biologists use mutated frogs, flies, mice, chicks, and fish to identify some of the major genes that regulate the development of a cell that determines whether to become a bone cell or a muscle cell.

But it's easier to see what errors occur when a gene is missing than it is to study finely coordinated differentiation in a petri dish. Understanding how some 25,000 human genes work together to form an organization, and figuring out the right genes that guide the development of immature cells, could keep scientists busy for decades. But if they succeed, those results will far outweigh their worth.

It should be cell metaplasia, after all, it is all differentiated.

The role of each cell is different.

It must be the cells that are multiplying and the cells are constantly differentiating.

**Cells differentiate into nerve cells.

The process of evolutionary selection of cells by division of labor.

**Turning nerves into nerve cells is not a normal procedure.

This won't be, it's already qualified, and it won't develop to others.

The diversity of cells has a clear division of labor.

Humans are multicellular organisms where the same cells cooperate with each other to come together to form a wide variety of organs. Together, we will sustain the life of the human body. The most important cells in our body are our ** cells, although they are not related in general, but in special cases** cells can differentiate to form nerve cells. This environment is the special environment given by scientific researchers. First of all, the first cells of the human body should be dedifferentiated to form a kind of undifferentiated cell.

These undifferentiated cells are induced to form nerve cells using chemically directed methods. And nurture it. This technology is still being studied.

If one day it is applied to medicine, then many incurable diseases will be solved.

There are countless ** cells in the human body, which actually become part of the nerve cells through the nerve chain, because ** cells are generally receptors of the human body.

After they stay in the human body for a long time, they will have some effects on some activities of the human body, and slowly turn into nerve cells.

The body's metabolic cycle is then gradually exchanged, so the nerve cells are transformed, which is a process of possession.

It's all because of the passage of time that they have grown like that, and the human body is a body that is constantly changing. Then it can be said that it has such a new change, which is also particularly normal.

What does a nerve cell make up of, and how do nerve cells work.

The basic structure of neurons can be divided into two parts: cell bodies and protrusions. The nervous system is made up of a large number of neurons.

These neurons are not structurally connected to each other by protoplasm, but only contact each other, and the site of contact is called synapses. There are two membranes at the synaptic site, called the presynaptic membrane and the postsynaptic membrane, and the synaptic cleft is between the two membranes. Therefore, a synapse is composed of three parts: the presynaptic membrane, the synaptic cleft, and the postsynaptic membrane.

The thickness of the front and back films is generally only about 7 nm, and the gap is about 20 nm. Within the axoplasm close to the anterior membrane contains mitochondria and synaptic vesicles, which have a diameter of 30 to 60 nm, which contain chemical transmitters. There is a vesicle fence formed by dense protrusions and grids on the medial side of the anterior membrane, and its void just accommodates a synaptic vesicle, which may have the effect of directing the synaptic vesicle to contact with the anterior membrane and promote the release of transmitters within the synaptic vesicle.

When the impulse from the presynaptic neuron reaches the synaptic body, the transmitters in the vesicle are released from the anterior membrane, enter the synaptic cleft, and act on the postsynaptic membrane. If this effect is large enough, it can cause an excitatory or inhibitory response in postsynaptic neurons.

The nervous system of the human body is made up of the brain, spinal cord, and nerves; The nerves emitted by the brain are called cranial nerves, and the nerves emitted by the spinal cord are called spinal nerves, so it can also be said that the nervous system is composed of the brain, the spinal cord, and the screaming nerves they emit; Or the nervous system is composed of the brain, spinal cord, cranial nerves, and spinal nerves The brain and spinal cord belong to the central nervous system, and the cranial nerves, spinal nerves belong to the peripheral nervous system, so the nervous system is composed of the central nervous system and the peripheral nervous system
