Stem cells repair the nervous system

Stem cells repair the nervous system.  The relationship between stem cells and the human body-stem cells are here to repair the nervous system!

As scientists’ research on stem cells gets deeper and deeper, it is possible for humans to use stem cells to treat Alzheimer’s disease.

The nervous system is the dominant function regulating system in the human body. Mainly composed of nerve tissue, it is divided into two parts: central nervous system and peripheral nervous system. The central nervous system includes the brain and spinal cord, and the peripheral nervous system includes the cranial nerves and spinal nerves.

The spinal cord is an important part of the nervous system, and its activities are controlled by the brain. Various sensory impulses from the limbs and trunk are transmitted to the brain through the conduction pathway of the spinal cord for advanced comprehensive analysis.

Spinal cord injury often leads to severe dysfunction of the limbs below the injured segment, and is also accompanied by spinal cord injury and other diseases, thereby affecting normal human life. The prevention, treatment and rehabilitation of spinal cord injury has become a major issue in the medical field today. The emergence of stem cell therapy may be able to change this situation.

Experiments have confirmed that transplanted stem cells into animal models of spinal cord injury can survive, migrate, reduce inflammation, release neurotrophic factors, reduce the formation of glial scars, and promote axon remyelination, thereby promoting the regeneration and recovery of injured spinal cord. Recovery of damaged functions.

Dr. Todd McDevitt, a scientist at the Gladstone Institute in the United States, and his team discovered a special type of stem cells. These cells are interneurons called V2a that send signals in the spinal cord to help control movement. When the researchers transplanted these cells into the spinal cord of mice, the interneurons could sprout and integrate with existing cells. This discovery provides new hope for the repair of spinal cord injuries.

Stem cells and degenerative diseases of the nervous system

Neurodegenerative diseases are caused by the loss of neurons or their myelin sheaths, which worsen over time, leading to dysfunction. Including Parkinson’s disease (PD), Alzheimer’s disease (AD), etc.

Japanese scientists used stem cell therapy to successfully restore the nerve function of a monkey model of Parkinson’s disease. This study shows that implanting human induced pluripotent stem cells (iPSC)-derived dopaminergic neurons can improve the exercise capacity of sick monkeys. The same method may be used to treat human patients with Parkinson’s disease.

This time, Kyoto University scientist Jun Takahashi and colleagues implanted these neurons into a monkey model of Parkinson’s disease to evaluate their safety and functional effects. The results showed that these human-derived cells can survive for a long time, play the role of midbrain dopaminergic neurons, and restore various motor functions of sick monkeys.

According to statistics from authoritative medical institutions, there are currently nearly 9 million Alzheimer’s patients in China. They have suffered a lot from forgetfulness for a long time. For example, forget the time, forget the way home, or even forget the relatives around you.

As scientists’ research on stem cells gets deeper and deeper, it is possible for humans to use stem cells to treat Alzheimer’s disease. Since stem cells are undifferentiated cells, they are the cells of origin of organisms. They have the ability of self-replication, proliferation, self-renewal, and multi-differentiation potential. They are primitive cells and adult tissue cells for the development of tissues and organs. Replacement, damage and repair of seed cells, this provides new ideas for the treatment of Alzheimer’s disease.
