The process of generating myelin is called myelination or myelinogenesis. In the CNS, oligodendrocyte progenitor cells (OPCs) differentiate into mature oligodendrocytes, which form myelin. In humans, myelination begins early in the 3rd trimester, although only little myelin is present in either the CNS or the PNS at the time of birth. During infancy, myelination progresses rapidly, with increasing numbers of axons acquiring myelin sheaths. This corresponds with the d… WebMar 27, 2024 · For example, myelin protein zero, a protein only found in the peripheral nervous system (PNS) of mammals, is present in the CNS of zebrafish (Brösamle & Halpern, 2002). Besides, zebrafish myelin also expresses some proteins that are absent in mammals, such as claudin K ( Münzel et al., 2012 ), 36 K ( Morris et al., 2004 ), and …
