WitrynaThe normal process of myelination of the brain mainly occurs during the first year of life. This process as known from histology can be visualized by MRI. Because of the very long T1 and T2 of immature brain tissue it is necessary to use adjusted pulse sequences with a long TR in order to obtain sufficient tissue contrast. With long TR SE images five … Witryna9 lis 2024 · The oligodendrocyte (OL) lineage transcription factor Olig2 is expressed throughout oligodendroglial development and is essential for oligodendroglial progenitor specification and differentiation.

These new cells become immature oligodendrocytes, which have branches but do not yet myelinate axons. Eventually, immature oligodendrocytes become adult, myelinating oligodendrocytes that can wrap myelin around many different axons. how are video games addictive

"Witryna8 maj 2024 · The myelination of axons in peripheral nerves requires precisely coordinated proliferation and differentiation of Schwann cells (SCs).
