Schwann cell (SC) grafts promote axon regeneration in the injured spinal cord, but transplant efficacy is diminished by a high death rate in the first 2–3 days postimplantation. Both hypoxic preconditioning and pharmacological induction of the cellular hypoxic response can drive cellular adaptations and improve transplant survival in a number of disease/injury models. Hypoxia‐inducible factor 1 alpha...
The objective of this study was to examine the possible role of the cysteine protease cathepsin B (E.C. 3.4.22.1) in the delayed neuronal death in rats subjected to the two-vessel occlusion model of global ischemia. Immunohistochemistry of the hippocampus showed an alteration in the distribution of cathepsin B in CA1 neurons from a lysosomal pattern to a more intense label redistributed into the cytoplasm...
DNA extracted from regional brain samples of hypoxic/ischemic neonatal rats showed internucleosomal cleavage indicative of apoptosis. Cells containing cleaved DNA were identified by in situ labelling in the cortex, hippocampus, striatum and thalamus of the ipsilateral hemisphere. When the effects of increasing the length of the hypoxia were examined, increases were seen in the amount of internucleosomally...
