|Abstract:||The transformation of amoeboid microglial cells into ramified microglial cells in the brain of postnatal rats has been studied by labelling the cells with the isolectin Griffonia simplicifolia (GSA1-B4). The latter served as a specific membrane marker of the cell type. Thus, at the light-microscopic level, the amoeboid microglial cells in 1- to 5-day-old rats were intensely stained with GSA1-B4. All the stained cells appeared round. In 10-day-old rats, while most of the stained cells were round, some had assumed an oval appearance. In older rats, i.e. 15-22 days, all the stained cells became flattened or fusiform with long cytoplasmic processes. The present electron-microscopic study confirmed the above features but also added the fact that the reaction for GSA1-B4 was localized at the plasma membrane in the amoeboid microglial cells in all the age groups studied. The reaction for the isolectin was also detected in some vacuoles in the cytoplasm of the round cells. It was concluded from this study that the round amoeboid microglial cells differentiate to become the ramified microglia with age. In the course of this transformation, they retained specific membrane receptors for the isolectin which distinguished them from other glial cell types.|
