Nasal glial heterotopia Nasal glial heterotopia Nasal glial heterotopia refers to congenital malformations of displaced normal, mature glial tissue, which are no longer in continuity with an intracranial component. This is distinctly different from an encephalocele, which is a herniation of brain tissue and/or leptomeninges, that develops through a defect in the skull, where there is a continuity with the cranial cavity. While nasal glial heterotopia (NGH) is the preferred term, synonyms have included nasal glioma. However, this term is to be discouraged, as it implies a neoplasm or tumor, which it is not. By definition, nasal glial heterotopia is a specific type
Glial scar the spinal cord lesion and this decrease was associated with a reduction in glial scarring. Chondroitinase ABC has been shown to degrade glial scars. Degrading the glial scar with chondroitinase has been shown to promote recovery from spinal cord injury, especially when combined with other techniques such as nerve guidance conduits, schwann cell transplants, and peripheral nerve autografts. Glial scar Glial scar formation (gliosis) is a reactive cellular process involving astrogliosis that occurs after injury to the central nervous system. As with scarring in other organs and tissues, the glial scar is the body's mechanism to protect and begin the
