glial tissue

glial tissue

Binding or connective tissue, especially in the nervous system. The glial cells of the brain, long believed to have only a supporting, nutritional and antipathogenic role, are now known to communicate with neurons and with one another, to have a function in the formation of synapses, and can determine which neural connections become stronger or weaker over time. It thus appears that glial cells are as important in thinking, learning and in the emotions as are neurons. Almost all intrinsic brain tumours are neoplasms of glial cells.

Another case was of immature cystic teratoma in a 5-year-old baby, which showed vascular proliferation with endothelial cells within the glial tissue (Figure 6).
Glial heterotopy is a midline, congenital mass located in the nose, which contains mature glial tissue. Although the incidence is not fully known, taking reported cases into consideration, it has been reported as 1:20.000-40.000 (1,2).
The clinical differential diagnosis of lateral nasal wall mass includes nasal dermoid, encephalocele, neoplasm, vascular malformation, and other various reported entities such as foreign body inclusion cyst and heterotopic glial tissue [8, 9].
These tumors, which are composed of a combination of neuronal and glial tissue, have been reported to account for 0.4% of all CNS tumors and 1-1.5% of all brain tumors [2-4].
Disc anomalies have common histopathologic characteristics: defects of the lamina cribrosa and the sclera, invagination of the retinal tissue into the excavation of the optic disc, attachment of the vitreous cortex and glial tissue to the invaginated retinal tissues, and presence of the subarachnoid space directly under the excavation site of the disc [1-3].
In 29 cases, a definite opinion could not be given on FS as the samples examined were nondiagnostic and included only necrotic, calcified, fibrous or glial tissue. This is due to heterogeneity of CNS neoplasms and sampling error.
(2) Because imaging of our patient was concerning for ectopic neural tissue within the defect, excision was recommended with histologic examination for neural or glial tissue.
Histopathological investigations of the mass showed a cystic neoplasm composed of various mature tissue components including skin, pilosebaceous glands, well-developed respiratory and gastric epithelium, and glial tissue with numerous psammoma bodies.
Malakar was referring to engineering students from the Indian Institute of Technology (IIT), located in the southern city of Chennai, who have developed algorithms using artificial intelligence that will help to improve diagnosis and treatment of glioma, a malignant tumour of the glial tissue of the nervous system -- but also MS.
Adult stem cells have the potential for regenerating the neurons and the support layer called glial tissue.
GBM and other high-grade gliomas are particularly aggressive cancers that arise from glial tissue and account for approximately 14,000 new cases of brain cancer diagnosed in the United States each year.
