Abstract
Objective: To culture astrocytes of optic nerve and to establish the cell lines for further study of healing process after optic nerve trauma.Methods: Optic nerve astrocytes of infantile and adults with sudden death were cultured by tissue inoculation or tissue digestion with 0. 25% Trypsin and 0. 06% EDTA. The second and fourth passage cells were stained with HE and anti- GFAP, S-100 protein, Vimentin, and CD34 antibodies.Results: The trypsinized astrocytes of infantile optic nerve reached confluence in 7 days,but the astrocytes of adults weren't successfully cultured. The cultured cells were in polygonal shape with processes; the cytoplasm was abundant and pink; the cells had light-blue nuclei. These cells were positive in GFAP, S-100 protein and vimentin staining, and negative in CD34 staining.Conclusions: The results showed that astrocytes of infantile optic nerve can be successfully cultured and trypsinization is a better method than tissue inoculation. The culture of infantile astrocytes is easier than that of adult astrocytes. Immunohistochemistry were used to determine the source and type of those cultured cells.关键词
