Sam Schmidt Paralysis Foundation a cell body, which houses the nucleus. Axons and dendrites form extensions from the cell body. Glial cells are "nerve-helper" cells that provide structural support, nourishment and protection for neurons. Astrocytes, a kind of glial cell, are the primary support cells of the brain and spinal cord. They make and secrete proteins called neurotrophic factors, which assist in the maintenance of nerve cells in the central nervous system. They also break down and remove proteins or chemicals that might be harmful to neurons (for example, glutamate, a neurotransmitter that in excess causes cells to become overexcited and die by a
Amniotic stem cells confirmed as mesenchymal stem cells were obtained. In addition, evidence indicated that embryonic stem cells are part of the fluid, although in very small quantities. At around the same time, it was determined that stem cells from the amniotic membrane also have multipotent potential. AS their differentiation into neural and glial cells as well as hepatocyte precursors was observed. The majority of stem cells present in the amniotic fluid share many characteristics, which suggests they may have a common origin. In 2007, it was confirmed that the amniotic fluid contains a heterogeneous mixture of multipotent cells after it was demonstrated
