Fluorescent Dye Prelabelled Microglial Cells Migrate into Organotypic Hippocampal Slice Cultures and Ramify
Tóm tắt
Microglial cells with their characteristic ramified morphology are exclusively found in healthy CNS tissue, whereas various pathologies are associated with the occurrence of amoeboid, macrophage‐like cells. It is still a matter of discussion whether amoeboid cells are blood‐derived macrophages, or whether a characteristic change in morphology, reflecting activation of previously ramified microglia, takes place. Cells in dissociated microglia culture obtained from healthy rat brains, inevitably developing this amoeboid morphology, were labelled with a fluorescent dye and transferred onto organotypic hippocampal slice cultures. Prelabelled cells with amoeboid morphology invaded these slice cultures and had, after 9 days
