Overview
iPSC-derived oligodendrocytes are human myelinating glial cells generated through directed differentiation of induced pluripotent stem cells (iPSCs). These cells closely model human oligodendrocyte development and provide a physiologically relevant platform for studying myelination, white matter biology, axon-glia interactions, and demyelinating diseases.
Because myelin dysfunction contributes to numerous neurological disorders, iPSC-derived oligodendrocytes have become an essential model for investigating multiple sclerosis, leukodystrophies, ALS, Alzheimer's disease, schizophrenia, and other white matter disorders.
Biological Significance
Oligodendrocytes are the myelinating cells of the central nervous system.
Major functions include:
- Formation of myelin sheaths
- Saltatory conduction of action potentials
- Metabolic support of axons
- Maintenance of long-term neuronal integrity
- White matter development
- Neural circuit maturation
- Remyelination following injury
- Axon-glia communication
A single mature oligodendrocyte can myelinate multiple axons simultaneously, making these cells essential for efficient CNS function.
