Modifications of ependymal cells membranes by galactocerebrosides in cell culture
In this paper we have demonstrated that treatment of ependymal cells in culture by galactocerebrosides induced a decrease in plasma membrane fluidity and an increase of EGF binding sites. We have shown in a previous work that galactocerebroside in vitro and in vivo caused an important morphological...

| description | In this paper we have demonstrated that treatment of ependymal cells in culture by galactocerebrosides induced a decrease in plasma membrane fluidity and an increase of EGF binding sites. We have shown in a previous work that galactocerebroside in vitro and in vivo caused an important morphological change in ependymal cells that grew into an astrocytic shape after a five day treatment. We discuss the hypothesis that the first event in morphological effect could be a modification of plasma membrane followed by important changes in molecules distribution. |
