title: Protein kinase C in astrocytes: a determinant of cell morphology.
abstract: Protein kinase C-like activity was found to be present in astrocytes prepared from rat neocortex and maintained in culture. Exposure to phorbol 12-myristate 13-acetate (PMA) caused a redistribution of this kinase from the cytosol to the membrane fraction of these cells. Also PMA was found to cause a profound change in astrocyte morphology; cells were converted from flat, polygonal, undifferentiated cells to process-bearing cells.
