To explore the biological role of carbohydrate chains in the process of nerve cell differentiation, we carried out a characterization of the carbohydrate structure of glycoproteins by comparing conventional PC12 cells with variant cells (PC12D). In vitro metabolic labeling of cells with either [(3)H] glucosamine or [(3)H] threonine, together with tomato lectin staining, revealed that nerve grow...
This study investigates the effect on: (1) the bulk surface and (2) the three-dimensional non-woven microfabric scaffolds of poly(N-isopropylacrylamide)-CNT-polyaniline on growth and viability of cells. The poly(N-isopropylacrylamide)-CNT-polyaniline was prepared using coupling chemistry and electrospinning was then used for the fabrication of responsive, non-woven microfabric scaffolds. The el...
The importance of glycans in biological systems is highlighted by their various functions in physiological and pathological processes. Many glycan epitopes on glycoproteins and glycolipids are based on N-acetyllactosamine units (LacNAc; Galβ1,4GlcNAc) and often present on extended poly-LacNAc glycans ([Galβ1,4GlcNAc](n)). Poly-LacNAc itself has been identified as a binding motif of galectins, a...
Four carbohydrate derivatives of poly-D-lysine have been synthesized and assayed as substrates for the tissue culture of embryonic mouse cerebellar cells. On poly-beta-(D-glucopyranosyl)-poly-D-lysine and on poly-beta-(N-acetyl-D-glucosaminyl)-poly-D-lysine, dissociated cerebellar cells formed a monolayer. On poly-beta-(D-galactopyranosyl)-poly-D-lysine, cellular aggregates were formed and cabl...
