Oligodendrocyte
Oligodendrocytes (from Greek, meaning cells with a few branches), or oligodendroglia (Greek, few tree glue), are a type of brain cell. They are a variety of neuroglia. Their main function is the insulation of axons (the long projection of nerve cells) in the central nervous system (the brain and spinal cord) of some vertebrates. (The same function is performed by Schwann cells in the peripheral nervous system). A single oligodendrocyte can extend its processes to 50 axons, wrapping around approximately 1 μm of myelin sheath around each axon; Schwann cells, on the other hand, can wrap around only 1 axon.

MS research: Myelin influences how brain cells send signals
The development of a new cell-culture system that mimics how specific nerve cell fibers in the brain become coated with protective myelin opens up new avenues of research about multiple sclerosis. Initial findings suggest ...

Researchers turn skin cells into neural precusors, bypassing stem-cell stage
Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers at the Stanford University School of Medicine. The finding is an extension of a previous ...

Neural stem cell differentiation factor discovered
Neural stem cells represent the cellular backup of our brain. These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. Astrocytes have supportive functions ...
