Summary
The influence of interstitial oedema on the survival of fetal raphe cells transplanted into serotonin (5-HT)-denervated rats and the fibre outgrowth from these cells was investigated. Fetal raphe cells were transplanted into the corpus callosum in which long-lasting interstitial oedema had been induced by intracisternal kaolin injection. The 5-HT and 5HIAA levels in the corpus callosum were restored to their maximum within 5–6 weeks post-transplantation regardless of whether interstitial oedema was induced or not. Furthermore, it was appeared that the presence of interstitial oedema even facilitated fibre growth as demonstrated by the 5-HT immunohistochemistry and the restoration of the 5-HT and 5-HIAA levels in brain areas distant from the transplantation sites. These results imply favourable effects of interstitial oedema on the survival of transplanted raphe cells and their fibre outgrowth.
