Dissociated sensory neurons were cultured on epitaxial gallium phosphide (GaP) nanowires grown vertically from a gallium phosphide surface. Substrates covered by 2.5 microm long, 50 nm wide nanowires supported cell adhesion and axonal outgrowth. Cell survival was better on nanowire substrates than on planar control substrates. The cells interacted closely(More)
Activation of extracellular-signal-regulated kinase-1/2 (Erk1/2) by phosphorylation to p-Erk1/2, and proliferation of Schwann cells were investigated in the rat sciatic nerve by immunohistochemistry. Axotomy in vivo and culturing of nerve segments in vitro resulted in a rapid (30 min) increase of p-Erk1/2 in Schwann cells with peaks at 2 and 24 h.(More)
The production of galectin-3, a carbohydrate-binding mammalian lectin, is upregulated in Schwann cells after peripheral nerve injury in areas where Schwann cells proliferate. Here we tested if galectin-3 affected proliferation of Schwann cells in cultured sciatic nerve segments. Galectin-3 significantly decreased the number of bromodeoxyuridine-labelled(More)
The first milk, colostrum, is an important source of nutrients and an exclusive source of immunoglobulins (Ig), essential for the growth and protection from infection of newborn pigs. Colostrum intake has also been shown to affect the vitality and behaviour of neonatal pigs. The objective of this study was to evaluate the effects of feeding colostrum and(More)
In this study, we developed a microdispenser technique in order to create protein patterns for guidance of neurites from cultured adult mouse dorsal root ganglia (DRG). The microdispenser is a micromachined silicon device that ejects 100 picolitre droplets and has the ability to position the droplets with a precision of 6-8 microm. Laminin and bovine serum(More)
A new type of agarose bead, superporous agarose, was used as a gel support for immobilization of human red blood cells (RBCs) mediated by wheat germ lectin. The number of immobilized cells was similar to that obtained with commercial wheat germ lectin-agarose but the cell stability appeared to be superior. This allowed improved frontal affinity(More)
