title: Uptake of radiolabeled glucose analogues by organotypic cerebellar cultures.
abstract: Permeability of brain cells to radiolabeled glucose analogues with sucrose or inulin or L-glucose was studied in the living, intact state of the organotypic cerebellar cultures. In vitro uptake of 3H 3-O-methyl D-glucose and 3H 2-deoxy-D-glucose exhibited saturation  kinetics with increasing substrate concentrations. Each of the labeled sugars uptake could be self-inhibited in the presence of unlabeled (cold) substrate and cross-inhibited with cold glucose or xylose or phlorizin present in the incubating medium. The uptake was Na-independent and stereo-specific for D-form.
