noun
- anatomy a glial cell involved in the formation of the myelin sheaths of nerve cell axons
Example Sentences
The researchers tried bathing oligodendrocyte precursor cells in dishes of morphine or dopamine and determined that neither chemical directly causes proliferation of these cells.
Additionally, researchers observed sex-specific differences in the aging process of certain brain cells, with the female cortex exhibiting a higher ratio of "old" oligodendrocytes to "old" neurons compared to the male cortex.
These useful cells in the brain, called oligodendrocytes, are responsible for producing myelin sheaths that wrap around cable-like parts of nerve cells called axons, much like the plastic insulation around a wire.
For oligodendrocytes -- the central nervous system cells critical for brain function -- age may not bring wisdom, but it does come with the power to cling to life for much, much longer than scientists knew.
The new study published today in the journal Nature Neuroscience, discovered that some common home chemicals specifically affect the brain's oligodendrocytes, a specialized cell type that generates the protective insulation around nerve cells.
