WebOne determinant of OPC density could be the necessity to generate OLs. Consistently, OPC density is low in CNS regions where unmyelinated axons predominate such as the molecular layer of the cerebellar cortex (Givogri et al., 2002; Sun et al., 2024). However, in other regions the distribution of OPCs does not match that of OLs. WebEnter the email address you signed up with and we'll email you a reset link. china ipad air 4 soft case dealer
