Spinal cord injury research different types of cells. The hope is that stem cells transplanted into an injured area of the spinal cord will allow neuroregeneration. Types of cells being researched for use in SCI include embryonic stem cells, neural stem cells, mesenchymal stem cells, olfactory ensheathing cells, Schwann cells, activated macrophages, and induced pluripotent stem cells. When stem cells are injected in the area of damage in the spinal cord, they secrete neurotrophic factors, and these factors help neurons and blood vessels to grow, thus helping repair the damage. It is also necessary to recreate an environment in which stem cells will grow.
Fred Gage that the human brain produces new nerve cells in adulthood. Until then, it had been assumed that humans are born with all the brain cells they will ever have. Gage’s lab showed that, contrary to years of dogma, human beings are capable of growing new nerve cells throughout life. Small populations of immature nerve cells are found in the adult mammalian brain, and Gage is working to understand how these cells can be induced to become mature nerve cells. His team is investigating how such cells can be transplanted back to the brain and spinal cord. They have showed that
