Abstract
The aim of the study was to test the hypothesis on the presence, in intact rat brain, of the cells located outside the ependymal layer, but possessing the structural organization and cytochemical characteristics similar to those of ependymocytes. The study was carried out on Wistar rats (n=10). Ependymocytes were identified using immunocytochemical reactions to ezrin and vimentin and were visualized with light and confocal microscopy. Cells, structurally and cytochemically similar to typical ependymocytes, were found outside the layer of ependymocytes in the nervous tissue of intact rat brain. It is suggested that extraependymal ependymocytes may have a function of reserve population of the neural stem cells in the brain.
