11. Its expression is lower in oligodendrocyte progenitor cells than in mature oligodendrocytes . 12. In the CNS, axons are myelinated by oligodendrocytes , thus lack neurolemma. 13. Hyperforin promotes mitochondrial function and the development of oligodendrocytes . 14. They are also present on both astrocytes and oligodendrocytes . 15. There is evidence of partial remyelinization and oligodendrocyte apoptosis. 16. Oligodendrocytes are responsible for the creation of myelin sheaths.17. Oligodendrocytes are a certain type of cell that functions to generate myelin sheath.18. Prolactin also stimulates proliferation of oligodendrocyte precursor cells. 19. Unlike astrocytes and microglia, oligodendrocytes undergo a much more limited reaction to injury. 20. Deficiency of RHEB in the forebrain of mice embryos is associated with decreased oligodendrocytes .
