ependymoma/carbohydrate

Recognitive interactions between the carbohydrate part of cellular glycoconjugates and endogenous receptors supposedly govern important biological processes. Consequently, their elucidation can be of considerable value in tumour diagnosis. The histochemical patterns of expression of endogenous sugar

Acid mucopolysaccharides (glycosaminoglycans) are identified by histochemical methods in biopsies of 107 human brain tumors. Isomorphous oligodendrogliomas and astrocytomas stained with alcian blue show marked, weblike, or diffuse distribution and concentration of acid mucopolysaccharides.

Antibodies against carbohydrates of three glycolipids were used to determine patterns of immunohistochemical reactivity of histologically identifiable cell subpopulations in 101 human primary brain tumors. For all tumor types fibrillary cells, polar cells, and gemistocytes (commonly seen in

The carbohydrate part of cellular glycoconjugates - glycoproteins, glycoproteins, glycolipids and proteoglycans - and specific endogenous sugar receptors, i.e. lectins, can establish a system of biological recognition based on protein-sugar interactions on the cellular and subcellular levels. To

A series of four medulloblastomas, seven neuroblastomas (Nb), two ependymomas, and three gliomas, human neuroectodermal tumors, were screened for their expression of adhesion molecules L1, carcinoembryonic antigen, neural cell adhesion molecule isoforms (N-CAM) and HNK1 epitope by Western blotting
